Sacgasco Limited, a natural gas developer and producer focused upon California’s Sacramento Basin, advised that drilling of the company’s over-1-Tcf Dempsey 1-15 well is proceeding according to schedule. The 13⅜-in. surface casing was set and cemented to a depth of 552 m. The rig is presently developing tools to drill in 12¼-in. hole. Company officials said reservoir sands will be drilled through at field-production levels in the next stage of the well, which is planned to be drilled in three sections to depths of approximately 600, 2000, and 3200 m, respectively. Sacgasco has identified seven target reservoir levels. Individual prospective resources of recoverable gas for the primary targets range from 116 to 352 Bcf. If the stacked reservoirs prove to be full of gas, the prospect’s cumulative unrisked recoverable prospective resources could be greater than 1 Tcf.
