A gas exploration well has 13-3/8” casing set at 6200 ft. Design a 9-5/8” casing string to be set at 10,400 ft in 73 pcf mud that will be subjected, in the event of a kick, to a formation pressure gradient of 0.57 psi/ft from the next hole drilled to a TD of 13,900 ft.

The 9-5/8” casing in stock at the pipe yard is:
