HOUSTON, July 21
– Mainland Resources Inc., Houston, has spudded the Burkley Phillips-1 well as a 22,000-ft test of Jurassic Haynesville shale in Jefferson County, Miss.

Based on data from the Chevron Long well drilled on the property in 1981, the new well should encounter at least 2,500 ft of Haynesville shale.

Chevron drilled to 22,000 ft to explore for the Smackover and Cotton Valley formations. It encountered an extremely high-pressure and thicker shale zone (22,000 psi) at 19,400 ft, compared with 8,000 psi at the typical North Louisiana Haynesville shale well.

The Chevron well was then drilled the next 2,600 ft as a controlled blowout but never reached Smackover formation and was plugged due to lack of technology required to complete in the shale in 1981 and certain casing problems uphole.
