Empyrean Energy provides update on Dempsey well in California's Sacramento basin


SUBIACO, Australia -- Empyrean Energy, the oil and gas development company with interests in China, Indonesia and the United States, is pleased to announce that it has been informed by Sacgasco Limited, the operator of the Dempsey 1-15 well in the Sacramento basin, onshore California, that the field appraisal drilling component of the Dempsey 1-15 well has been successfully concluded. Dempsey 1-15 has reached the planned intermediate casing point and has been wireline logged.

The wireline and mud logs have confirmed four zones of interpreted gas saturated sandstones at field production levels at depths from approximately 1,000 m (3,300 ft) to 1,560 m (5,100 ft).Based on log correlations and 3D seismic, these gas filled sands have not been previously produced in this fault block of the field.

The net gas pay estimate from the logs ranges from 30 to 50 ft, depending on petrophysical-parameter cut-off values used. These zones will now be protected behind casing for future testing and production.

As planned, 9 5/8-in. casing has been run to a depth of approximately 1,760 m (5,800 ft), and is currently in the process of being cemented in preparation for drilling ahead into more than five prospective underlying sandstone reservoir targets.
