Oil well completions require various highly technical devices and tools operated by knowledgeable operators. A tubing anchor is one of the primary tools needed to aid production and job efficiency. Here, we explore how tubing anchors work in well completions and highlight a few key features.

An Anchor’s Basic Functions

An anchor catcher is a unique device that can improve overall performance and production inside the wellbore. Rod pumping can experience a few common issues, such as reduced efficiency or ballooning, and with the assistance of an anchor catcher, these issues are kept at bay. The anchor will provide tension between the tubing string and casing at the most appropriate depth.

During a wellbore’s pumping cycles, the tubing anchor performs two functions simultaneously that increase overall well efficiency. The anchor can prevent any parted pipe from falling into the well and causing further issues. The primary security source in these processes is the overall set tension because the tension is critical for preventing buckling. With the proper use of an anchor catcher for tubing string, operators can reduce accrued costs from damage or a lack of efficiency.

A Closer Look at a Drag Block

A drag block is often the primary tool used for tension placement. Sometimes, there is excessive vertical movement that causes issues with the wearing of the rods. A drag block is 100 percent retrievable and adjustable in the event of an emergency and is available in various size preferences.

There are a few key features worth noting for a drag block’s proper use and function. These tools are ideal for any hardness grade, including premium. The hand-set releases are variable and allow total efficiency whether you require left-hand, right-hand, or emergency shear releasing. Additionally, the wicker slips provide bi-directional movement prevention in case the tubing experiences motion.
