Which of the following most accurately describes the problem?

a Thornycroft Big Ben 21-ft.-wheelbase six-wheeled chassis, has been shipped to Libya for use by the B.P. Exploration Co. The rig is designed for drilling with a 2-in. drill pipe to a depth of 2.500 ft. or with a 2?,-in. pipe to 4,000 ft. It is the first all-British designed mobile rig of this capacity.

The rig was built by Armstrong Whitworth (Metal Industries), Ltd., and its equipment includes a tubular steel mast which can be raisea and lowered by hydraulic rams. This gives 58 ft. clearance above the rotary table.
