High-Accuracy Oriented Perforating Extends Sand-Free Production Life of Andrew Field

摘要

BP began development of the Andrew field in 1996 with 13 producer wells and one gas-injection well.Oriented perforating was used in some wells to reduce the risk of sand production from the weaker sandstone intervals.At the time,the accuracy of oriented perforating was unknown.The full-length paper describes the evolution to high-accuracy orienting systems on three new Andrew wells and two workover wells.
