AUTOMATED HIGH TORQUE WRENCH LEADS TO 60% LESS DEFORMATION WHEN APPLYING FORCE TO DRILLPIPE

 


An exploration and production (E&P) company with operations in the Midland Basin was battling over-torqued connections and trying to mitigate the resulting drillpipe damage. Between Q3 and Q4 of 2021, a considerable number of their drilling connections had to be broken with manual tongs. In addition to slowing the connection process down and reducing the life of the drillpipe, a larger threat was the added safety exposure. With tong events attributing to a large percentage of crew time in the red zone, they knew they needed a new solution that could break connections at a higher torque than 60,000 ft-lbs.

H&P introduced the HexGrip™ 120 wrench, a newly released proprietary tool designed to help solve the torque challenges the industry is facing and provide ancillary benefits to operators. This high-torque automatic wrench is capable of making tubular connections up to 100,000 ft-lbs. and breaking out connections at 120,000 ft-lbs., making it ideal for long lateral applications that require higher torque. Its centrifugal grip has 6 dies in a 360° pattern to hold the tool without egging the tubular box – leading to 60% less deformation when applying force to the drillpipe. With the touch of a button, it enables remote control automation of a tubular connection, reducing human interaction and the possibility of an accident.

With the HexGrip 120 wrench, the operator was able to collect a host of data points that provided analytics of tubulars and downhole dynamics. This list included make-up and break-out torques to help ensure that the pipe was torqued to specification and to identify any over torque events downhole.

DRILLSCAN® SOFTWARE IDENTIFIES DRILLING DYSFUNCTION CAUSES IN COMPLEX, MULTILATERAL ERD WELL

Image
An operator in the North Sea faced a lower completion lock-up 800m above total depth (TD), followed by a stuck pipe event in an ERD multi-lateral well. In an initial effort to push the completion down to TD, all slack off weight and torque margin were used. Since no improvement was observed, the decision was made to pull-out. However, the string remained stuck and despite the rig efforts to free it, the lower completion had to be cut and left in hole. H&P’s DrillScan® technology team performed an in-depth post-analysis, reviewing all available data to identify what might have caused the lock-up event. The data provided was used to simulate the downhole conditions undergone by the completion with the DrillScan genuine stiff-string model. The results and conclusions pointed to string dysfunctions: suboptimal tripping and lubricating/ backreaming practices (BHA POOH) led to repeatedly exceeding the screens yield strength (lower completion RIH). H&P’s DrillScan software was a...
