  • New slimhole rotary steerable system at work in Sultanate of Oman


    H. Owens, D. Carrington and Dr. G. Downton

    A new drilling technology ensures as smooth a wellpath as possible, while at the same time increasing rate of penetration (ROP). It enables greater control of directional drilling using constant rotation to intersect more targets in a longer hole section, and it minimizes the risk of stuck pipe. The new technique – slimhole rotary steerable system – was first used in completing three onshore wells this past spring and summer: Safah Wells 198, 204 and 203. This article describes Occidental Oman’s experience using the new system in drilling these wells.
