A study of the economic and technical differences between inverted emulsion muds and water-based muds in the Springer formation of the Anadarko basin of Oklahoma shows advantages for oil muds in drilling, completion, and production operations. In particular, each fluid was examined to determine the severity of formation damage associated with its use. There were eighteen wells in a twelve township area in Caddo and Grady Counties of Oklahoma, in the study. They were evaluated from the top of the Springer formation to total depth. The Springer is a marine deposit composed of several tight dry gas sands with permeabilities less than 0.1 md. Nine of the wells were drilled with water-based mud to the intermediate casing point, which is in the transition zone between normal and abnormal pressure in the Morrow shale directly above the Springer formation.
