Drilling and Completion of Khuff Gas Wells, Saudi Arabia

ABSTRACT This paper will review the program for drilling and completing the primary well configurations for 4-1/2 in. (114.3 mm) and 7 in. (177.8 mm) Khuff gas completions in Saudi Arabia. The drilling programs associated with these configurations and the typical drilling problems and geological considerations relevant to casing point selections will be outlined, as well as types, weights and grades of casings typically run. In addition, drilling fluids, cementing programs and wellhead equipment will be reviewed. Finally, completion procedures will be discussed and drilling performance to date will be reviewed showing improvement since initial wells were drilled.
