Keystone also carries slip-type elevator parts, including rings, hinge pins, latch pins, cotter pins, latch locks, and slip bolts.

Safety Concerns with Rig Floor Equipment

When drilling operations call for the use of slip-type elevators (as opposed to, for example, a bottleneck type elevator), the following precautions should be taken:

  • Slip-type elevators must close completely, and the latch must engage properly. Double-check the elevator body, latch mechanism, links, and dies and setting plate. Keep hands away from any pinch point or undesignated areas; use only the provided handles for operating the elevator.
  • Elevators should be cleaned frequently to reduce the risk of slippage, and to ensure that they are working properly. If slips are used, make sure the dies are clean and sharp, and all of the same size. Do not mix old or resharpened dies with new dies in either the elevator slips.
  • If a tubing spider is used, make sure it does not crimp the tubing when is closed. Make sure it releases completely to avoid gouging the tubing when lowering.
  • Check the condition of the slip bushing to ensure that the slips will fit properly and engage the tubing evenly. Properly fitting and well-maintained equipment can reduce the risk of damaging the tubing.
  • Check the size and rating of the power tongs. The size should not be more than one size larger than the tubing being run and the tongs must be able to attain the expected maximum torque. Check the rig-in of the power tongs, making sure that the tong back-up line is at right angles to the tongs. Check that the tongs are level and free to move and are at the correct height above the floor. Make sure the power tongs are equipped with an accurate and reliable torque gauge.
  • Make sure the back-up tongs are sized properly, have clean and sharp die segments, and won’t damage the tubing. Don’t use pipe wrenches as back-ups!
  • Blocks should be completely stopped prior to latching the elevators on the pipe. The blocks must be raised slowly to allow the elevators to slide up to the pipe upset area. Check that the blocks are centered over the rotary table. Any misalignment can result in difficulty when stabbing and spinning up connections.
  • Pipe should be stood back in the derrick no further than necessary, eliminating as much “bowing” as possible. Personnel responsible for “tailing” the pipe should keep the pipe at arm’s length at all times.
  • Workers should never position themselves directly under stands or joints of the drilling string. Use a tail rope that allows employees to stand well away from the pipe at initial pick-up.

Life on an oil rig can be tough enough without footwear that lacks the comfort, protection and durability to handle the rigorous demands placed on the wearer day-in and day-out. Just like other forms of personal protective equipment (PPE) — hard hats, eye protection, gloves and aprons — picking the right footwear for the job is essential.

What should you look for in selecting a boot that’s sturdy, safe and comfortable — one you can wear throughout long shifts without taxing your feet or rubbing them raw?

Consider these six characteristics when picking out your next pair:

Type of Toe Cap

Boots reinforced with hard toe caps are required for use on oil rigs due to the risk of heavy machinery or sharp metal objects striking the foot resulting in injury.

The three most common types of work boot toe caps are steel, composite and aluminum. All three are OSHA-approved and protect against impact.

Steel toes provide the best puncture protection but can be heavy. Composite toe boots, made from materials such as plastic, carbon fiber and rubber, are lightweight yet durable. Aluminum toes offer another choice for lightweight protection while still meeting ANSI/ASTM safety standards.

Slip Resistance

Slips and falls are responsible for some of the most common oil right injuries, so it makes sense to find a boot that has soles with a tread pattern and outsole material designed to reduce the chance of slipping.

Of the three kinds of soles on the market — rubber, TPU and EVA — rubber is the most well-suited for use in the oilfield. Its natural gripping property provides resistance to abrasion, oil, sediment and chemicals. TPU also provides resistance to abrasion, oil and chemicals as well, however, and may be a good alternative. EVA soles, while comfortable, are soft and flexible but can compact over time and with wear.

Boot Construction

The way the boot is made, how it attaches to the sole and how resistant it is to wear and tear are all important considerations when it comes to making a work boot purchase decision.

Boots construction comes in one of two forms: cement and welt.

Cement construction

Cement construction (also known as direct-attach) involves fastening the upper part of the boot to the sole using molten rubber. Cementing utilizes a durable and flexible adhesive to bond the outsole to the rest of the boot. Boots made this way are also affordable, lightweight and mold to your feet for comfort.

The only problem with this form of construction is that once the sole becomes damaged or starts to separate from the boot, it’s not easy to repair, which means you may have to replace the entire boot.

Welt construction

Boots constructed using welting, where a sturdy strip of leather, rubber or plastic is stitched to the upper part of the boot and sole, make for a better-made, albeit more expensive boot. For the oilfield, it is likely the better option that direct-attach construction due to its ability to withstand wear and tear.

There are two welting versions: Blake and Goodyear.

Blake welting wraps the upper around the insole and attaches it to the outsole by a single stitch. Goodyear welting or double-stitched is the oldest method and uses two-level stitching, which results in the most durable (though also most costly) boots.

Welting construction allows boots to be re-soled or repaired, thus extending the life of the footwear.

Comfortable Fit

While you must factor in the choice of the toe cap, type of sole and construction into consideration, if, at the end of the workday, your feet are sore or blistered due to an ill-fitting boot, you haven’t helped yourself.

So, add to the list of characteristics the need for a comfortable boot that conforms (as much as possible) to the shape of your foot. The good news is that boots come in a broad range of sizes, include regular and wide widths and have extra padding. When trying on the boot for the time, you want it to feel snug but not too tight.

Designed for Safety

To be on the safe side, only purchase boots that are OSHA-approved. That ensures they comply with standards set by the American Society for Testing and Materials (ASTM) and by the American National Standards Institute (ANSI).

Tips for Boot Buying

Keep these tips from BeThePro.com, a construction industry resource site, in mind when shopping for your next pair of work boots:

  • Do your research first. Find out what PPE your job requires before making a purchase. Also, talk with industry peers to learn what they recommend.
  • Shop for boots in the afternoon or early evening. Feet tend to swell throughout the day, so try on footwear in the afternoon or evening to ensure your work boots will feel comfortable all day.
  • Bring your socks. Bring a typical pair of socks that you might wear to understand better how your boots might fit.

Conclusion

Of all the reasons to buy a work boot — comfort, affordability, durability  — when it comes to working on an oil rig, always make safety the top priority.

Look for a boot that is OSHA-approved and ASTM-rated, and one that protects your foot against damage from heavy machinery or falling objects, resists slippage and is well-insulated against extreme heat or cold. Don’t let lack of proper footwear be the reason for a fall or other injury even if it means spending a little more. Your feet will thank you for it!

In case you haven’t heard, natural gas production in the United States has shot up in recent years and is expected to keep climbing.

New drilling techniques such as hydraulic fracturing (fracking) have made us the world’s top producer of natural gas. Additionally, new processes for shipping liquefied natural gas (LNG) could make the U.S. a bigger player in international natural-gas markets in the years to come.

This “shale revolution” (and the possibility of it expanding into new markets) is, in many ways, starting here in Keystone Energy Tools’ backyard. That’s because, at present, only one U.S. LNG export facility is fully operational — Cheniere Energy’s Sabine Pass terminal in Louisiana. In this article, we’ll talk about how other the construction of facilities should help the domestic energy market spread to China (and other trade partners) in the years to come.

The LNG Market Oversupply

2018 got off to a cold start in much of the country, so naturally, the demand for natural gas for heating went up. According to the U.S. Energy Information Administration, in the first week of January, America shattered its previous record for natural gas consumption, pulling 359 billion cubic feet of natural gas from storage to meet demand.

Overall, however, domestic gas production is outpacing domestic demand, and we have too much unsold gas in storage. At the Sabine Pass LNG terminal, located on over 1,000 acres along the Sabine Pass River in Cameron Parish, some 3 billion cubic feet of natural gas is liquefied and exported daily. Such exports are helping us turn our oversupply into profit, but it’s not enough now, and it won’t be enough in the days to come.

Domestic LNG processing is set to explode in the next few years, but the facilities needed to export them aren’t there yet – except for the one in Louisiana. LNG plants like Sabine Pass are made up of trains, which are liquefaction facilities used to “supercool” natural gas for transport on ships (LNG is natural gas cooled to liquid form). In October, Sabine Pass added a fourth train, boosting output by a third.

Another terminal is scheduled to open soon on Maryland’s Chesapeake Bay, and at least three other terminals in Georgia, Texas and Louisiana are expected to be online by 2019. By then, the U.S. LNG capacity will be the third largest in the world.

Still, unless Congress passes legislation to expedite the process, the United States will find itself at a competitive disadvantage with other LNG exporters (including Australia, Malaysia, Qatar and Russia). Regulatory roadblocks have hampered the construction of more LNG facilities – facilities that could answer the growing demand for America’s natural gas supply.

New Opportunity in China

In 2017, China became the world’s second-biggest importer of liquefied natural gas (behind Japan and just ahead of Korea). The demand was fueled by China’s growing interest in switching from coal to cleaner natural gas for its domestic energy need. Just as the shift from coal to natural gas has done in the U.S., China’s gasification program is intended to improve environmental conditions there.

China’s demand for natural gas is expected to reach 330 billion cubic meters in 2020, up from 206 billion last year, and the United States is well-positioned to capture a significant share of that rising demand. Assuming we can build out the infrastructure that is needed.

What Will It Take?

The U.S. is now a net exporter of natural gas (meaning we export more than we use) for the first time in 60years. U.S. LNG exports would help diversify world energy supplies and enhance global energy security. Clearing the path to the world’s fastest-growing LNG markets (in China and elsewhere) would show that the United States is committed to its role as a global energy leader.

What is needed to turn America’s massive shale-gas supply into a commodity exported to China and other markets? Aside from more export facilities, we need to help countries build the regasification and distribution facilities they need to import our LNG. One encouraging trend gaining traction is regasification facilities on ships. These ships can go to wherever the purchasing country has constructed its pipeline network and make it easier for U.S. producers to make inroads into new international markets.

LNG Frequently Asked Questions (courtesy of Cheniere Energy)

What is LNG?

LNG is liquefied natural gas (methane) that has been cooled to an extremely cold temperature (-260° F/ -162.2° C). At standard atmospheric conditions, methane is a vapor, not to be confused with gasoline, which is a liquid.

How is LNG shipped?

Specially designed ships are used to transport LNG to U.S. terminals. They have double hulls and are constructed of specialized materials that are capable of safely storing LNG at temperatures of -260° F/ -162.2° C.

Where do ships unload LNG?

Ships unload LNG at specially designed terminals where the LNG is pumped from the ship to insulated storage tanks at the terminal. LNG is also converted back to gas at the terminal, which is connected to natural gas pipelines that transport the gas to where it is needed. Specially designed trucks may also be used to deliver LNG to other storage facilities in different locations.

How is LNG stored?

LNG is stored in double-walled, insulated tanks that are designed to prevent any gas from escaping. There is also a dike or impounding wall around the tank that is capable of containing the entire volume of the tank, in the unlikely event of a spill. This would prevent any LNG from flowing off the site.

Is LNG explosive?

In its liquid state, LNG is not explosive. When LNG is heated and becomes a gas, the gas is not explosive if it is unconfined. Natural gas is only flammable within a narrow range of concentrations in the air (5% to 15%). Less air does not contain enough oxygen to sustain a flame, while more air dilutes the gas too much for it to ignite.

How is public safety addressed?

In the event of a spill, LNG vapors will disperse with the prevailing wind. Cold LNG vapor will appear as a white cloud. To keep the public safe, flammable vapor (gas) dispersion exclusion zones are established for LNG facilities.

If LNG is spilled in the presence of a flame, a localized fire will result. Since this fire would burn with intense heat, thermal exclusion zones are also established.  Flammable vapor and thermal exclusion zones are determined to keep the public at a safe distance from LNG facilities.

How are LNG tankers and facilities being kept secure?

Security measures for land-based LNG facilities and onshore portions of marine terminals are required by U.S. Department of Transportation regulations. Examples of these requirements include security patrols, protective enclosures, lighting, monitoring equipment, and alternative power sources. Interstate natural gas companies receive security updates and alerts on a regular basis from federal agencies, including the FBI.

Hydraulic and pneumatic power tongs include drill pipe tongs, casing tongs and tubing tongs. With all types, your crew needs safe, efficient, reliable performance with a good torque-to-weight ratio.

Here’s a little more info about different rig tongs:

Drill Pipe Tongs: Used to screw industrial tubular together to form a drill string and its components, which make the drill bit turn at the bottom of the wellbore.

The drill string includes the drill pipe, bottom hole assembly, a kelly or top drive motor and any other in-hole equipment used during drilling operations. These tongs should be effective at lowering drill time and reducing costs. They typically come in sizes 2.36 to 10 inches.

Casing Tongs: Used to make or break casing tubulars placed in the drill hole to maintain the well opening.  They can handle lightweight casing and have torques ranging from 15,000 to 200,000 foot-pounds. Typical sizes are from 5.5 to 36 feet.

Tubing Tongs: Holds and rotates tubulars used for oil and gas extraction. They are ruggedly designed to perform at higher torques required to break premium connections. Like casing tongs, they also come in a variety of torque specifications.

Quality Tongs

Quality tongs improve the efficiency and safety of drill floor operations. These large-capacity, self-locking wrenches apply torque where needed when making up or breaking out tubing. Just like a plumber using opposing pipe wrenches, rig tongs are always used in opposing pairs. One set of tongs is tied off with a cable or chain to the derrick, and the other is pulled with mechanical catheads.

Tongs used during makeup (tightening) operations are called makeup tongs; the ones used during breakout (the process of unscrewing drill string components) are called breakout tongs. Depending on the specific application, there are also riser tongs, chisel tongs, rotary tongs and manual tongs.

During makeup operations, the “lead tongs” (pronounced “leed”) are the pipe tongs suspended in the derrick or mast and operated by a chain or a wire rope connected to the makeup cathead or the breakout cathead.

The tong pull line is a length of wire rope with one end connected to the end of the tongs and the other to the cathead on the drawworks. When the driller actuates the cathead, it takes in the tong line and exerts force on the tong to either make up or break out drill pipe.

The lead-tong hand is the crew member operating the lead tongs when drill pipe and drill collars are being handled and pipe is going into the hole. For breakout operations, breakout tongs are used to start unscrew sections of pipe from one another, primarily drill pipe coming out of the hole.

Tong dies play a key part in helping power tongs or manual tongs grip tool joints. Running in or pulling out tubular at oil rigs, the tool joints are adjusted with power tongs or manual tongs.

Dies are pieces of serrated steel installed in the tongs that grip the tool joint of drill pipe when the tongs are latched onto the pipe. Tong dies are made of alloy steel, and their hardened surfaces resist wear. The inner ductile core minimizes the shock of impact and torque.

Calculating Torque

During makeup, how much force should be applied to the tongs to get the torque needed? The formula to determine torque value when you use the rig tong to make-up the connection is this:

Torque=Force x the Length of the tong

Where:

  • Torque is measured in feet/pounds
  • Force is measured in pounds
  • Length of the tong is measured in feet
  • Force is perpendicular to the length of the tong

Keystone Tubing Tongs

Keystone’s K-Series tubing tongs are pull-tested and complete documentation is available with each purchase. Designed for heavy-duty service of tubing 1.050 to 3.875-inch OD, they offer a wraparound design with approximately a 300-degree die contact to prevent crushing of thin wall tubing.

Keystone Tubing Tongs

The KET K-25 tubing tong has a wide range (1.050 to 2.875-inch) and can be used by hand or with a rope block and cat line during makeup and breakout operations. They are made of high alloy steel, heat-treated for strength and wear, and then tested. The KET K-25 tubing tong also has a 2,000 foot/lb maximum torque rating.  The K-30 tong has a 5,000 foot/lb maximum torque rating and a 1.660 to 3.875-inch range.

We also carry tong die drivers and tong safety handles.

Working on an offshore oil rig is a hazardous job even under the best conditions. That’s why smart companies put such a strong emphasis on safety. Thanks to a growing “safety first, job second” culture, offshore oil rig fatality rates have decreased steadily over time, according to the CDC.

Still, whether it’s the result of exposure to hazardous chemicals, falls, fires, explosions or contact with equipment, oil rig injuries and fatalities continue to occur. Here are ten ways to prevent them.

1. Instill a Safety-first Mindset

Ensuring workplace safety, particularly on oil rigs, must be a top priority that embodies the mindset, attitude and behavior of workers, supervisors and managers alike.

As such, it’s in your best interest to consistently remind everyone on the rig — both employees and subcontractors — of the importance of maintaining a safe work environment, which includes following all safety rules and regulations and keeping alert to possible hazards.

Leadership who “walks the talk” is always helpful in setting a standard for safety. If management commits to safety, workers will follow suit. Workers won’t buy-in, however, if they don’t see policies and procedures being followed by their superiors.

2. Require Orientation

All new and transferred rig workers should undergo a mandatory orientation, like SafeGulf or IADC RigPass, before being allowed on the rig floor. Such orientation helps employees and contractors become familiar with company and rig operational policies, expectations and worksite rules, thus producing a safer work environment.

3. Train Workers Consistently


Following orientation comes training, and that’s not a one-time event but an ongoing proposition. It includes instruction on the machinery and equipment in use as well as on safety procedures. Providing consistent training for employees demonstrates your commitment to safety and is yet another way to instill a safety-first mindset.

4. Wear Required Personal Protective Equipment


All sites require mandatory personal protective equipment (PPE), including safety glasses, hard hats, gloves, steel-toed boots, respirators and fire resistant clothing. That doesn’t mean, however, that all rig workers wear them.

A good rule of thumb: If you do not wear the right PPE, you are not allowed on site.

Quality protective gear is essential to avoiding injury. It’s better to wear the equipment and not need it than not to wear it and wish you had.

5. Implement a Positive Reporting Process


Building a safety-first culture is easier when employees feel the freedom to report concerns and believe management will take them seriously. Instead of responding negatively (or even acting punitively) to employees who report potential hazards, reward them for their efforts.

The reporting process should also include the right to stop work when a possible safety hazard is detected. While it’s not popular to stop the job, a safety-first mindset means that protecting someone from a potentially life-threatening situation trumps production every time.

6. Build a Community of Trust and Respect


Safety training should always involve a human element. That means facilitating ways for workers to get to know one another. Doing so will build a sense of camaraderie, trust and mutual respect. As workers form personal relationships, it stands to reason they will look out for each other’s best interest and be more willing to ask for help, obey rules and seek advice in making decisions — all of which leads to overall safety enhancement.

7. Communicate Safety Regularly


Holding weekly or monthly safety talks is an excellent way to instill a safety mindset among workers. Rather than just lecture, however, use interactive small group discussions to involve everyone, and allow time for questions. Other ways to communicate safety is to make safety policies available online and on paper and use your intranet to share best practices, updates and news.

8. Educate Subcontractors


Safety must be the chief concern of everyone on the rig, and that include subcontractors. Select only those whose safety record exemplifies that priority and refuse to bring anyone on the rig which doesn’t. Take them through the same orientation and training that you would expect from your employees.

9. Conduct Routine Housekeeping


Keep floors, pathways and work areas clear of unnecessary items to prevent trips, falls and struck-by hazards. Also, clean up drilling fluids that may collect on the rig floor during pipe handling operations, and display signage that directs workers to emergency and safety equipment, to combat hazards quickly.

10. Keep Machinery Well-maintained


Conduct regular maintenance checks of machinery to prevent premature failure, which could present potential hazards, and then repair or replace damaged or inoperable parts and equipment quickly.

Putting workers at risk due to a worn out part that could break at any moment is irresponsible and unnecessary. Maintain the integrity of the equipment, and you ensure a safer work environment.

(Implementing a mechanical integrity program that includes inspection, testing and quality assurance in keeping with BSEE SEMS II (30 CFR 250.1916) is another to promote a safety-first culture.)

Conclusion


Every industry has some risk involved but none more than the oil and gas industry. Taking safety seriously, particularly on oil rigs often located hundreds of miles offshore, is no small matter.

Don’t wait for an injury or fatality to occur before you take action to prevent accidents; be pro-active instead. Implement these ten guidelines and make “safety first, job second” a rallying cry that all your employees and subcontractors will gladly echo.

Oil and gas is growing in the Gulf South, but low prices and an increasing supply mean the operations we service are still watching every penny. Let’s take a look at the changing production landscape, then review how Keystone meets the industry’s need for high-quality parts at competitive prices.

Rig Count Continues Its Rise

There are nearly twice as many active rigs in North America as there were this time last year. The higher rig count means there are fewer underutilized assets, which puts oilfield services companies in a stronger position. The giant rig suppliers like Halliburton and Schlumberger are raising prices on oil producers in response.

This gives smaller suppliers (like Keystone Energy Tools) an opportunity to provide value and personal service where the big guys can’t. For us, more rigs mean more orders for consumable products (like float valves) and capital products (like elevators) for drilling rigs. Since float valves are replaced 10-15 times per well, and since elevators need to be replaced whenever they wear out, those of us in oilfield supply are working hard to meet the demand.

On top of everything else, oil prices remain low. After trading above $50 per barrel for much of the first and second quarter, West Texas Intermediate (WTI) prices fell sharply over the summer and are now back to where they were earlier in the year. Even though prices have been creeping up, they remain low enough to compel drilling operations to pinch pennies wherever possible.

Keystone has made a niche for itself servicing these drilling operations, particularly the ones who need to cut costs with (often) smaller orders of high-quality oilfield tools, including drill pipe float valves, stabbing guides, baffle plates/valves, valve pullers, rotating mouseholes and tong blocks. The larger suppliers often can’t be bothered with these smaller orders of specialty products, and they certainly can’t match our personal service and expertise.

The Boom Close to Home

Although Keystone services oil and gas operations around the globe, we don’t have to look far to see opportunities for partnership. Here in Louisiana, for example, an old fracking “hotspot” is popular again.

The Haynesville Shale, a giant natural-gas field in the northwest part of the state, was all but abandoned when prices fell a few years ago. But in 2017, companies like Chesapeake and QEP Resources Inc., as well as a few newcomers, are back in the Haynesville, where gas production is currently over 7 billion cubic feet per day.

There are 44 active rigs active in the Louisiana parishes and Texas counties that make up the massive dry natural gas formation. The most active areas are in Caddo, Bienville, Bossier, DeSoto, Red River and Webster Parishes, plus adjacent areas in southwest Arkansas and east Texas.

The Haynesville rebound has been part of an overall Gulf Coast recovery that has seen the construction of new petrochemical facilities, fertilizer plants and gas-export terminals. Chesapeake and the other operators there have been extracting more by drilling and fracking longer wells. New technology is being used to re-frack old wells where production was considered complete.

The U.S. Energy Department forecasts that between now and 2040, consumption of natural gas will increase more than that of any other fuel source, which means the boom times in our backyard should continue for years to come.

It’s not all great news, however. The weak price performance over the last few months has been enough to impact U.S. shale production and growth. Domestic operators put the brakes on drilling plans as their expectations for a recovery in oil prices were lowered.

With the world’s top oilfield services companies complaining that shale growth is decelerating, there is no doubt the industry is gun-shy about drilling themselves into another depressed market.

Keystone: Here for the Long Haul

As a leading manufacturer and distributor of oilfield equipment, Keystone offers consumable and hard-to-find tools and supplies to upstream oil and natural gas drilling companies. Our product line includes the following:

  • Handling tools are used for suspending, moving and rotating tubulars in and around the well center and on the drill floor;
  • Keystone’s dies and inserts provide the accuracy you need for critical applications, with dies that securely grip the hardest strings of casing, tubing, and drill pipe and inserts designed to maximize your drill’s rate of penetration;
  • Keystone Energy Tools also has safety products, including safety flex handles for slips, safety handles for manual tongs, mud buckets and iron roughnecks, tong die drivers, safety make-up stands and slip lifting devices.

If you’ve ever received the wrong piece of equipment because one of the big suppliers didn’t take the time to get your order right, you know how easy it is to feel like you’re being ignored. That won’t happen with us. Even on small jobs, Keystone takes the time and care to make sure you get the correct product.

Keystone carries quality oilfield tools at a price you can afford and at a level of quality that ensures consistent reliable operation. Keystone’s representatives provide fast turnaround on request for quotes. We carry the deepest “stocked” inventory of hard-to-find tools and equipment, and we specialize in helping service and drilling contractors get back on-line in the shortest amount of time.

Modern shale gas exploration means more horizontal wells, longer laterals and more frac stages.  The market shift to horizontal wells has also brought different horizontal frac completions methods. The benefits and drawbacks of two of them, “plug and perf” (or limited entry) and pinpoint fracturing, continue to spark debate among operators.

We won’t solve that debate here. The technical discussion is far from over. But we can briefly look at the two completion methods and outline their characteristics. What’s the difference between limited entry and pinpoint entry, and what are the pros and cons of each?

Limited Entry Fracturing

Plug and perf (or limited entry) is the preferred and most common fracturing method for unconventional wells. Often employed in wells with cemented liners, it involves pumping down a bridge plug on wireline with perforating guns.

The operator sets the plug at a horizontal location near the well toe, and the zone is then perforated. Next, the tools are removed from the well, and the fracture stimulation treatment gets pumped in. A ball-activated plug diverts fracture fluids through the perforations and into the formation. As the operator repeats the “plug and perf” process for each stage, the downhole tools move from the end of the wellbore back to the beginning until each stage has been fraced.

Limited entry operations are predictable and repeatable—two things operators love. However, limited entry comes with its limitations.

One disadvantage is that it creates multiple permanent entry points per target fracturing stage, with multiple perforations per entry point over dozens of target stages along the length of the wellbore.

Since multiple perforation clusters are stimulated simultaneously, there is no control over the size of each fracture. Some clusters are not stimulated at all, while others receive varying amounts of treatment. The result is gaping areas of the formation that remain unstimulated.

This lack of control during frac placement opens the door for disruptive technologies that address these concerns in very tangible ways.

Which leads us to “pinpoint” fracing …

Pinpoint Entry Fracturing

With limited entry (discussed above), drillers frac multiple clusters ( a group of perforations intervals or zones) at the same time. Most drilling operations in the United States include five clusters per stage. Some oil and gas operators are experimenting with an increased number of clusters (up to 16 per stage).

There’s a significant group of big operators (including ExxonMobil, Shell, Apache, among others) that seem to be convinced it is extremely challenging to accurately and equally frac each zone, all at the same time, with limited entry. Therefore, they prefer to treat each area individually. That’s where pinpoint, or single-point entry, fracturing comes in.

Pinpoint fracturing can improve near-term and long-term well performance compared to plug-and-perf. It provides consistent, repeatable fracture placement along the entire lateral of each well and from well to well.

Zones are isolated with sand plugs, and operators can frac each cluster individually with coiled tubing in the well. This approach allows operators to optimize the stimulation design for a given formation.

Locations of fracture initiation are verifiable and consistent because pinpoint fracturing treats a single cluster at a time. The amount of proppant and fluid pumped into each fracture is consistent.

Pinpoint fracing has been growing in popularity, and many service companies have designed completions systems around it. Indeed, several completions companies are cropping up lately that sell specialized tools for unconventional multistage fracturing. That said, one of the big selling points of pinpoint stimulation is that it requires less equipment and a smaller footprint.

Operators who end up going back to plug and perf say the maximum number of stages they can frac with pinpoint stimulation is a limitation, as is the pump rate they can achieve. They also cite cost and operational inefficiencies.

For example, one of the most successful pinpoint frac systems these days comes from NCS Multistage. The systems are limited by the maximum depth and flow rate they can achieve; both issues are because they require coiled tubing to activate their sleeves.

What Do You Think?

While many single-point entry fracturing adopters have found it increases oil production, several big players stick with the more traditional plug-and-perf method. What’s your opinion? What do you think is next in stimulation technology? What emergent methods will be the next “big thing” in hydraulic fracturing?

Today’s deeper drilling calls for long and heavy casing strings. Drilling a well through rock formations means using casing to keep the sides of the well from caving in and to protect the wellstream from contamination.

At a basic level, casing slips are steel wedges hinged together. Just like rotary hand slips, they are used to grip the tubular pipe and carry the weight of the whole string to keep it from falling into the well. When the tubular is suspended into the rotary, the slips will wedge between the rotary bushings and the OD of the tubular. The weight of the pipe itself is what will keep it in place.

Casing slip

Casing pipe, or “setting” pipe, typically involves running steel pipe into the well and cementing it into place. “Joints” that are generally 40 feet long are screwed together to form the casing strings. Casing runs from the rig floor, with casing elevators connecting one joint at a time. The casing is stabbed into the previous casing string in the well.

Landing the casing depend on the forces exerted on the casing string after the well is completed. These forces can be caused by fluid density, formation pressure, temperature and earth compaction. The casing will shrink or expand in response to these forces.

“Dies” and “slips” are often used to describe the same thing, but technically the die is a part of the slip. Dies on the inside of the slip grip the pipe and evenly distribute the force from the wedges to the surface of the pipe to avoid crushing. “Dressing the slip” involves inserting thicker or thinner dies to change the gripping size.

Keystone “CMSXL” casing slips have a 4-inch taper and a range of 6 5/8 inches through 30 inches (which can be accomplished by adding or subtracting the number of segments and installing the proper button sizes).

Keystone “CMS-3” casing slips are designed to fit spiders and bushings with a 3-inch taper. The CMS-3 has a size range of 9 5/8” through 30 inches. As with the CMSXL, by adding or subtracting segments and inserts the slips can accommodate 30-inch O.D. casing.

The Keystone CMSXL and CMS-3 casing slips have a multi-segment design to give a full wrap-around to help prevent damage to casing. Segments are made of alloy steel and are heat-treated for strength and wear resistance, then machined to strict quality controlled standards.

Tips for Safe Operation

When using manual slips, it’s important to keep safety in mind. Casing slips should not be thrown in the rotary table, especially when the string is moving as doing so can damage the equipment. Slips should be inspected before a job, and all dies should be checked for sharpness and correct size. Casing slips can break if the string exceeds the load rating.

Finally, even if different parts of various manufactures seem compatible, they may not be, so it’s best to stick to Keystone-made parts. Get a price quote from Keystone Energy Tools on quality oilfield tools today by clicking here and filling out our form.
