Geopressured - geothermal drilling and testing plan. Pleasant Bayou No. 2 Well, Brazoria County, Texas

Technical Report · Sat Mar 31 23:00:00 EST 1979

OSTI ID:6031201

As a result of the resource assessment studies, the Brazoria fairway, located in Brazoria County, Texas, was determined to be an optimum area for additional studies. The drilling, completion, and testing of one geopressured-geothermal well (i.e., GCO-DOE Pleasant Bayou No. 1) and two disposal wells in Brazoria County were contracted. Pleasant Bayou No. 1 was spudded on July 2, 1978. Drilling proceeded and on November 17, 1978, a depth of 15,675 feet had been reached. Unstable hole conditions resulted in the pipe becoming stuck while attempting to cut core number 10. A series of hole problems, including bridges, well kicks, stuck pipe, formation breakdowns, and erosion casing at some places in the intermediate, forced the plugging back of Pleasant Bayou No. 1 to the bottom of the 13 3/8-inch casing at approximately 8,400 feet. This hole will be used as one of the two planned disposal wells. This revised plan describes moving the rig 500 feet southwest of the Pleasant Bayou No. 1 and drilling the offset Pleasant Bayou No. 2, using the same program objectives as was established for Pleasant Bayou No. 1.
