Abstract:For several years, the author has participated in the design and installation of equipment for many deep Anadarko Basin wells, including the two deepest wells ever drilled. Most of the early Anadarko deep completions featured large OD production tubing, anticipating high productive well capacities; but more recent completions have been made with smaller 2 7/8" OD tubing, and the problems of tubing stress are quite serious. For instance, well shut-in pressures may reach to over 12000 psi. Fracturing with proppa… Show more
