GEOG 4891 Study Guide - Midterm Guide: Casing String, Polyethylene Terephthalate, Overburden
Document Summary
Average formation water density of a field is 8. 65 pound per gallon. For this field answer following questions: (5/100) calculate the normal formation pressure gradient (hydrostatic pressure. Calculate (not directly from the table) make-up loss per joint for 5 inch od (or de) and 15 lb/ft weight j-55 grade casing with short threads and coupling . Also calculate the loss for 1555 m of casing string, and the casing string length required (lt) for 2744 m of made-up string. Calculate joint strength of casing given in question 2 (5 inch, 15 lb/ft, grade j-55 casing with short threads and couplings), and maximum length of casing satisfying required joint strength.
