Technical limit thinking produces steep learning curve ///

Technical limit thinking is a conceptual feedback tool for maximizing drilling efficiency. It involves first determining the conditions and engineering practices that will lead to the minimum time and/or cost at which a given well can be drilled, and then employing motivational and training techniques to implement those practices. Shell and Petroleum Development Oman (PDO) produced a highly developed technical limit program for the challenging Saih Rawl gas field, which culminated in the landmark drilling of the field’s first sub-60-day well, Saih Rawl 228, in 57.89 days, against an AFE time of 75 days. Shell and PDO leveraged the methodology to further teamwork, knowledge management and bit optimization to progressively reduce well construction time. BACKGROUND Saih Rawl is an onshore deep gas field in southern Oman and the biggest gas field in the country. It is split into three geographically and tectonically separated blocks: SR Main to the north, SR Graben and SR South.
