Weir Oil & Gas, an upstream provider of systematised pressure pumping and control equipment, have announced their new Weir Latch Back Pressure Valve (LBPV) Drill-Thru System
The system, available with their Lock-Ring (ULR) Wellhead and S-29 Lock-Ring Wellhead, increases the safety and reliability of drill-thru operations.
In place of a conventional thread profile which often gets damaged while running the drill through the wellhead, the new system used a proprietary latch design, eliminating the threat of damage to the BPV, non-productive time from stuck drill bits and pressure integrity issues.
Unlike a H-Type BPV, the new LBPV system streamlines the design to simplify retrieval, replacement, and maintenance. The NPT cost for traditional BPV operations can be more than $100,000, but the Weir LBPV System reduces human error and expenses, resulting in immediate improvements in reliability.
The system has a pressure rating of 15,000 psi and can be installed using a dry rod lubricator or high-tier hydraulic lubricator to place the plug. It provides operators the assurement that the latch will hinge every time even after wear, offering east retrievability and replaceability.
“Our Latch Back Pressure Valve System addresses some of the greatest challenges drilling engineers face,” said Paul Coppinger, President, Weir Oil & Gas. “We engineered our LBPV Drill-Thru System to take the entire drilling operation into account. The latch technology enables drilling crews to improve overall well design cost and well performance, by allowing them to drill deeper and more efficiently, reduce NPT, and mitigate the possibility of a catastrophic pressure event.”
