The Slimline TAC in Shallow Wells

With traditional B2-style TACs, the benefits gained from securing a well’s tubing must be balanced against the negative effects of the anchor itself. A traditional TAC essentially creates a “choke point” within a well, because the annular space between the anchor OD and the casing ID is so small. In turn, that choke point can create a pressure drop that leads to the formation of scale, iron sulfide and paraffin. When those minerals are present, plugging is often the result. Plugging occurs when sediment bridges off on top of the anchor and effectively cements it in place. No fluid can fall past the anchor, and no gas can flow up.

The Slimline® TAC — and variations like the Slimline® Full Bore TAC and Slimline® QuickSet™ TAC — mitigate these issues. The Slimline anchor’s reduced OD creates up to 245% more flow-by area than a standard B2 TAC. That increase allows the Slimline TAC to deliver the benefits of anchored tubing without creating additional challenges around scale formation and gas locking.

Even in Shallow Wells, a Tubing Anchor Catcher Can Deliver Big Benefits

Petroleum engineers well understand the value of including a tubing anchor catcher (TAC) in deep-well downhole production strings. With relatively shallow wells of 5,000 feet or less, however, the consensus is not as universal.

Sometimes operators will leave shallow wells unanchored to maximize profit margins. The rationale is that the additional cost of adding a TAC would outweigh any resulting gains in productivity. But research tells a different story.

4 Key Considerations When Running a Quick-Setting TAC

Use caution when running the anchor in and out. While this piece of advice sounds obvious, it’s especially important when working with the Slimline® QuickSet™. Because the QuickSet™ anchor can be set and released in 1-to-3 turns, as opposed to the traditional 6-to-8 turns, being cautious and deliberate about how the anchor is run in and out of a well is even more important than with a traditional TAC.

Put a right-hand turn in the tubing occasionally. To prevent the tool from setting while running in, it is advisable to occasionally (about every 5-to-10 stands) put a right-hand turn in the tubing. Doing so will help prevent the anchor from setting prematurely. (If you are running a right-hand set TAC, put a left-hand turn in the tubing.)

Use a pipe wrench instead of power tongs. When adding that right-hand turn every 5-to-10 stands, it’s important to use a pipe wrench instead of power tongs. The pipe wrench will allow you to feel when the tool is fully released and avoid damaging it. If you use power tongs, you could over-release the tool and shear the pipe plug. In turn, the anchor could bind up and fail. If there are times when it isn’t feasible to use a pipe wrench to add the right-hand turn – such as in very deviated or deep wells – the power tongs should be set to slow speed.

Slow down. Especially when going through a tight spot in the well or when hitting fluid, it’s essential to take a slow, deliberate approach to running, placing, and setting the anchor.

Assembly Tip: Inserting Slips into the Anchor Housing

Watch as TechTAC's Midland Regional Manager Weston Hendricks demonstrates an ideal way for inserting slips into the Slimline® anchor housing

The many benefits of running a Slimline® Tubing Anchor Catcher are realized, in large part, thanks to the anchor’s reduced OD. However, when it comes to assembling the TAC, that smaller OD can create some pretty tight spaces. In particular, without the right technique, inserting slips into the anchor housing can lead to some frustration and colorful language.

TechTAC® Slimline® Tubing Anchor Catchers Benefit from a Unique Design

In wells with sucker-rod pumps, tubing anchor catchers, or TACs, can stabilize the production string. That stability creates higher pump efficiency and minimizes wear on rods, tubing, casing and the rod pump.

However, in addition to the benefits, standard B2-style TACs, along with other traditional anchor designs, are also susceptible to several common problems that can hinder production.

In contrast, the design of the TechTAC® Slimline® Tubing Anchor Catcher creates a reduced OD, which in turn provides up to 245% more flow-by area between the anchor and the casing ID.

According to an independent CFD study, that increased flow-by area means the Slimline® creates far less pressure drop, turbulence and turbidity than a standard B2 anchor.

That free flow of fluid helps mitigate the frequency and impact of stuck anchors and gas locking, which in turn can help operators significantly reduce costs and increase production.

A senior completion foreman with a U.S.-based oil and gas company described the benefits this way: “We have one well that had to be pulled every 3 months due to scale. After installing a Slimline TAC, we didn’t need to pull it for 2 years.”

Because the annular area between the TAC and well casing is so small, sediment and scale can bridge-off on top of the anchor and cement it in place, often resulting in an expensive fishing job. At the same time, the TAC essentially acts as a choke, trapping formation gas below the anchor, leading to a gas locked rod pump.

Nickel-Coated TACs and the Fight Against Corrosion

Coating downhole equipment with nickel can help inhibit corrosion. That’s why TechTAC® offers nickel-coated TACs as one of its many options.

In wells where certain highly corrosive elements are present, coating downhole equipment with nickel can help to inhibit the corrosion that equipment experiences. In turn, operators have more production time before a tool assembly has to be pulled and replaced. That’s why TechTAC® offers nickel-coated TACs as one of the many options within its suite of tubing anchors.

The TechTAC® Slimline® is NOT a Specialty Tool

The TechTAC® Slimline® TAC is not a specialty tool. In most cases, it can provide better performance than alternatives like standard B2 TACs

During a recent Tech Talk, hosted by SPE and sponsored by TechTAC®, our team fielded several questions from the audience. All the questions were insightful, but one of them stood out. After seeing many varied applications for the Slimline® Tubing Anchor Catcher, the attendee was rethinking her preconceived idea that the Slimline® TAC was just a specialty tool. She asked:

“Based on the data you’ve shared, it sounds like [the Slimline® TAC] isn’t just a specialty tool. Could it be used in any well?”

The short answer is, yes. While our team would argue the Slimline® TAC is special (i.e., unique), it’s not a specialty tool. In fact, a recent CFD study highlights how most wells can benefit from running the Slimline® TAC.

Benefits of Oilfield Anchors

The use of oilfield anchors in oil wells brings numerous benefits, all contributing to the efficiency, safety and cost-effectiveness of oil extraction. Here are some key benefits:

Reduced Wear and Tear. Oilfield anchors, or tubing anchors, minimize the vertical movement of the tubing string, which significantly reduces wear and tear on both the tubing and the associated equipment. This reduction in mechanical stress extends the lifespan of the well components, leading to lower maintenance costs and fewer operational interruptions.

Enhanced Safety. The stabilization provided by oilfield anchors enhances the overall safety of the well operation. Preventing uncontrolled tubing movement reduces the risk of accidents and equipment failures, protecting both the workforce and the environment from potential hazards.

Improved Pump Efficiency. In wells that use rod pumps or other artificial lift systems, oilfield anchors improve the efficiency of the pump by keeping the tubing string stable. This stability ensures that the pump operates at optimal performance, leading to better extraction rates and reduced energy consumption.

Cost Savings. The combination of reduced maintenance, extended equipment lifespan, and improved operational efficiency translates to significant cost savings for oil companies. By investing in quality oilfield anchors, companies can achieve a higher return on investment through more reliable and efficient well operations.

Consistent Production. Stabilized tubing helps maintain a steady flow of oil, ensuring consistent production rates. This consistency is crucial for meeting production targets and maximizing the profitability of the well.

Which Oilfield Anchor is Best for Your Well?

Many varieties of oilfield anchors, or tubing anchors, are sold to accommodate the needs of different well designs. No matter the style, however, the anchor’s primary purpose remains stabilizing the production string. For decades, the industry has relied on standard B2 tubing anchor catchers to perform this important function. Unfortunately, standard B2 anchors can also inhibit a well’s production. A study by Echometer Company examined the production rates of 11 oil wells. Each well had high fluid levels and the pump intake was located below the perforations. Yet despite these seemingly favorable conditions, nine of the wells showed a pump fillage rate of less than 90%.

According to the report: “In these wells that exhibited high fluid levels … the fluid distribution in the wellbore below the liquid level was not uniform. The wellbore in the vicinity of the pump intake was primarily filled with gas with a minimal volume of liquid. …The presence of a tubing anchor set high above the pump intake is considered to be the main cause of this uneven distribution of fluids in the wellbore.

“The particular tubing anchor used in these wells provides a flow area of about 2.9 square inches between the body of the anchor and the casing compared to a flow area of 14.4 square inches between the casing (4.892-inch ID) and the tubing (2.375-inch OD). The small flow area could increase the velocity of the upwards flowing gas to the point where it would be difficult for liquid present in the upper part of the annulus to flow downwards past the depth where the tubing anchor is set. The anchor would essentially act as a choke and also cause an increase of the annular back pressure.”

In other words, the tubing anchor itself was restricting the flow of gas up through the annulus of the well. The gas that did escape had an increased velocity. That velocity made it difficult for fluid above the anchor to fall past it and reach the pump. In turn, the fluid around the pump had a high gas content, making highly efficient production impossible.

Understanding the Purpose and Benefits of Oilfield Anchors

In the oil and gas industry, maximizing efficiency and safety are paramount. One of the critical components that contributes to these goals is the oilfield anchor. Often called a tubing anchor, tubing anchor catcher or TAC, this relatively small piece of equipment plays a significant role in ensuring the smooth operation of oil wells. This post will delve into the purpose and benefits of oilfield anchors, highlighting their importance in the extraction process.
