HOUSTON – Weatherford International plc’s Shallow Angle QuickCut System has achieved what it claims is the industry’s first 12¼-in. casing side track, delivering a 22-ft (6.7-m) window in a single trip for an ultra-deepwater well in the Gulf of Mexico.
“The operator contacted Weatherford to perform a Gulf of Mexico ultra-deepwater exit in a 12¼-in. heavy wall casing,” said Chip Miller, Vice President, North America Geozone, Weatherford. “This successful 12¼-in. side track casing became an industry first, made even more complicated by the need to achieve a dogleg low enough for production packers to safely pass through the resulting window.”
The company and the operator deployed the Shallow Angle QuickCut with MultiCatch Anchor and milled the 22-ft casing window and 15-ft (4.6-m) rat hole in a single trip.
“This industry-first serves as a best practice for successfully exiting heavy wall casing, opening up a contingency scenario that was previously not feasible while at the same time, allowing operators to tap into bypassed reservoir sections safely and efficiently,” said Miller.
