Abstract

A dual horizontal oil producer completed in offshore Abu Dhabi faced unplanned faults while drilling the 8.5” pilot hole, resulting in complete losses. Based on this event, deployment of radioactive sources in the horizontal section presented highly risky geosteering operations, potentially leading to extensive fishing operations in case of a stuck pipe. The alternative technology adopted was to utilize a high resolution LWD resistivity imaging tool for wellplacement applications and reservoir characterization in a water based mud system. The case study achieved increased production due to maximizing reservoir contact by utilizing accurate realtime dip picking and together with qualitative at-bit resistivity measurements.
