This program has be effective in cleaning the hole as well as increasing drilling progress.IntroductionOver the last decade many hole cleaning recommendations have been based on laboratory experiments under controlled conditions. These experiments normally involved a flow loop with an inner pipe which was meant to stimulate a drill string in a wellbore. The inner pipe may not have been rotated during these experiments. If it was rotated the revolutions were often low (<100 rpm). Also, the pipe was nearly always laterally restrained. Under these conditions, several of these experiments have indicated that pipe movement is not a primary factor in hole cleaning. Despite this, field personnel engaged in extended reach drilling operations have not only shown pipe movement, i.e. high rpm, to be important in the hole cleaning but have used pipe movement as a basis for developing effective hole cleaning programs. This paper describes one such program developed by Amoco UK over the course of three extended reach wells. The objectives of this hole cleaning program have been to improve extended reach drilling performance by:Avoiding stuck pipe.Avoiding tight hole on connections and trips.Maximising the footage drilled between wiper trips.Eliminating hole cleaning backreaming trips prior to reaching casing point.Maximizing daily drilling progress.A discussion of how this hole cleaning program has been implemented and its positive impact on extended reach drilling performance is presented below.Amoco UK Extended Reach WellsIn the course of developing the hole cleaning program, Amoco UK has drilled three extended reach wells: Arbroath Field wells T14 and T19 in UK Block 22/17, and North Everest Field well SEER T12 in UK Block 22/10a. All these wells drilled the same type formation (shale and limestone) using generally the same hole and casing sizes, mud weights and drill string configuration.P. 425 Keywords: penetration rate, drilling engineer, down-hole condition, wiper trip, drilling operation, drilling performance, mud system, torque, active mud system, reach well Subjects: Drilling Operations This content is only available via PDF. 1995.
