| - Petrov Oil is the largest offshore jack-up oil and gas well drilling corporation, with 55 offshore jack-up and 7 semi-submersible drilling rig's servicing the U.S and other international areas Its primary drilling locations range from 50 to 600 miles (970 km) offshore, in the North Sea, Africa, Middle East, Asia Pacific, South America, and the Gulf of Mexico, Australia Coast, Soviet Union Kingdom Coast Line, Russian Federation Coast, JBR Nation Coast. Petrov Oil's jack-up rigs are positioned in ocean depths of up to 400 feet (120 m), with each of 3 legs being driven into the ocean floor for stability, by pumping ocean water into onboard tanks, weighing up to 6 million pounds, to drive each reinforced rig leg up to 100 feet (30 m) into the sediment and rock. Petrov Oil semi-submersibles have no connection or anchor to the ocean floor, and maintain their location by Dynamic positioning via GPS and computer-controlled 4,000–6,000 horsepower Rolls-Royce azimuth thruster or Flowserve propulsion units, in up to 10,000 feet (3,000 m) of ocean, and drill down to 38,000 feet (12,000 m) into the Earth's crust for oil and natural gas deposits.
