Reworking

Continental Resources Inc. disclosed Tuesday that it has begun reworking a legacy shale play in south-central Oklahoma geographically similar to the Bakken, Marcellus and Eagle Ford shales that could add 1.8 million boe to its reserves in the next few years.

Although the physical reworking of storage wells will go on through the winter, Southern California Gas Co. on Thursday began crediting some of its poorest retail customers with low-cost supplies being mined from its so-called “cushion” supplies used to maintain ideal pressures at two of its underground storage fields.

Long-ago one of the nation’s centers for oil and natural gas production, Southern California, with today’s historically high oil and natural gas prices, is experiencing a resurgence of reworking some of its old wells, many of which are surrounded by housing and commercial development. Improved technology and the high wholesale prices have given the area’s wells a “new lease on life,” according to a report in Monday’s Los Angeles Times.
