Schlumberger Launches Deepwater Vessel
Schlumberger introduced DeepSTIM — an advanced stimulation vessel.
Launched last month for operation in the Gulf of Mexico, the vessel measures 260 x 56 ft. with its large capacity providing reliability in unfavorable weather conditions — allowing it to remain at sea for extended periods. A fully enclosed North Sea-style deck houses all pumping, mixing and blending equipment — eliminating exposure of equipment and personnel to weather. Equipped with the most recent technology in antiroll systems, environmental waste containment, data acquisition and transmission, and fluid engineering, the vessel runs at 12,700-hhp at rates of 50 barrels per minute. DeepSTIM can also increase its hhp, with 48 hours notice, to 19,500-hhp. A process controlled, continuous-mix fluid system permits "on-the-fly" mixing of both acid and fracturing fluids utilizing fresh water or seawater, thus significantly minimizing fluid wastes and reducing material costs. Features include an innovative dynamic positioning system, which allows the vessel to remain at a programmed position using computersupported thrusters constructed into the vessel's hull. A high-speed satellite communications package allows transmission of critical wellsite information.
