Sorheim, bread maker Hughes Figure 1: Many NCS fields keep going formation instability or depletion. Liner while drilling has been considered promising in these situations. Above is the SDL operational procedure. The worlds first steerable drilling liner system has been successfully field-tested by Statoil and Baker Hughes in the Norwegian sector of the coupling Sea. Historically, operators and service companies focused on drilling performance optimization and reducing the time to ache from spud to total depth. Parameters such(prenominal) as rate of penetration, reducing non-drilling time and minimizing the overall depart time were targeted for improvement and certainly continue to be today. everywhere time, operators growing necessity to enter mature and depleted reservoirs and areas with elevated pressure variations brought with it more complex operational risks.

New approaches were unavoidable that dealt with these challenges safely and economically. STEERABLE DRILLING LINER Since the early 1990s, some(prenominal) operators have used casing or liner drilling systems to overcome formation/wellbore stability problems, but with limited functionality. Because the grocery for these systems was then considered a niche market, development of more various(a) systems languished. Improvements in other drilling and formation evaluation techniques and liner hanger technologies paved the way for the steerable drilling liner system. Baker Hughes and Statoil collaborated in the development of 7-in. (8½-in. hole) and 9 5/8-in. (12¼in. hole) steerable drilling liner systems. Operators around the world face drilling...
