A preliminary oil well drilling program has been completed for a new well. The production string is of OD = 5 inches set at a depth of 12,000 ft. A production string program [detailing the applicable Casing depth, casing OD, hole size, and mud weight] has been proposed (see below). Using the API Casing Data Sheet (in Blackboard), and safety factors (burst = 1.1, collapse = 1.2, tension = 1.7), select appropriate: A) Casing weight and grade for the Surface casing B) Casing weight and grade for the Production casing Drilling section Casing Depth (feet) Casing size (inches) Hole size = Bit Size (inches) Mud Weight (ppg) Surface casing 1500 10.75 15 8.85 Intermediate 4500 7.625 9.875 9.65 Production 12000 5 6.5 10.7 casing
