Workover and recompletion of subsea completions in the Gulf of Mexico
Atlantic Richfield Co. is now operating 8 subsea wells offshore Louisiana. These wells are in the Eugene Is. Block 175 field. The average water depth for the field is 85 ft. Three subsea wells required remedial work because of normal reservoir depletion and various mechanical problems. Basic assumptions in the planning phase are presented and the work performed to move in the workover rig and to establish contact with the well is summarized. Atlantic Richfield found that subsea completions in the Gulf of Mexico can be successfully re-entered and worked over in water of moderate depths with diver-assisted operations. Basic considerations, including proper rig selection, blowout-preventer stack and marine riser types, and eduction of diving personnel are essential to a successful workover program.
