fax 01-972-952-9435. AbstractThe Ram-Powell Unit encompasses eight OCS leases in the Viosca Knoll Area of the Eastern Gulf of Mexico. The blocks are located approximately 125 miles east, southeast of New Orleans and approximately 80 miles south of Mobile, Alabama in water depths ranging from 2,000 to 4,000 ft. Since the drilling of the discovery well on Viosca Knoll Block 912 in May 1985, five commercial pay sands have been logged between 5,500 and 13,500 ft subsea.This paper describes the planning and successful execution of the highly challenging A9 extended-reach well designed as the first development of the G sand interval. G sand represents the new geological play for the field as it is approximately 1,500 ft shallower than the main reservoir horizons of the field. The well was designed as a combined exploration and development project and a fast-track completion scheme was devisedThe authors will discuss the design strategy, which focused on hole cleaning and the urgency of getting the casing to bottom immediately after drilling. The drilling and completion team employed a systematic approach to planning and execution of the well, which integrated both drilling and completion.Along with detailing the planning and execution of the project, the authors also will detail the lessons learned, including the difficulty in distinguishing between borehole instability and hole cleaning problems when pulling out of the hole.
