From the start of the current phase of North Field drilling activity in 2002, RasGas Company Limited (RasGas) has continued to push the envelope in terms of both technology and operating practices in drilling and completions. Following the successful introduction of an Optimized Big Bore (OBB) well design in 20021,2,3, advancements have been made in areas of drillstring design, drilling optimization techniques, management of lost circulation events and overpressured water flows, and stimulation technology associated with increasingly longer completion intervals. This paper highlights how these advancements have enabled year-on-year improvement in drilling and completion cycle times, even though well complexity has increased over the same time period.
