First Dopeless technology well drilled in Alaska’s North Slope

An European oil and gas company has drilled the first Dopeless technology well in Alaska’s North Slope, on the northern part of the Brooks Range on the coast of the Arctic Ocean. The company was able to save approximately 6.1 hours of rig time and 84 manhours, according to Tenaris. The TenarisHydril Wedge 521 and Wedge 563 premium connections with Dopeless technology were used on an L80 steel grade. There were zero rejects and zero re-makeups after running 750 joints with Dopeless technology.

The technology was able to increase visibility of the pipe threads due to the application of the Dopeless coating, which was a significant advantage during make-and-breaks. “Dopeless technology is a perfect fit for an environmentally sensitive region like Alaska,” said Fernando Sanchez Moreno, North and Western US Sales Director for Tenaris.
