New anchor designed for smart well operation

摘要

D&L Oil Tools has released a new patent-pending design for hydraulically and mechanically-set retrievable tubing anchors/ catchers named Trilobite Anchors. The anchors are designed with three heat-treated steel alloy slips, which can maximize holding in both tension and compression. The anchors are also made with strategic component spacing, to allow increased annular flow and capillary tube bypassing. This allows for operators to increase space for gas while running capillary lines, all without compromising tubing size in the desired 5 1/2-in. by 2%-in. configuration. The new anchor also serves as a "catcher," meaning it does not require upward tension to remain in place.
