The long-awaited for ExxonMobil well offshore Liberia on Block LB-13 came up dry. According to the US supermajor’s JV partner, Canadian Overseas Petroleum Ltd. (COPL), the Mesurado-1 reached final depth on December 17 but encountered no hydrocarbons.
The well, drilled using the Seadrill West Saturn, was targeting oil in a sequence of Late Cretaceous Santonian aged sands. During drilling it intersected 145 meters of net sand of which 118 meters was deemed to be reservoir quality. No hydrocarbons were indicated by the logging while drilling operations performed across the targeted intervals. As such,ExxonMobil advised COPL that no further logging operations will be conducted and the well will be plugged and abandoned.
“We are naturally disappointed by the lack of hydrocarbons in the targeted reservoir sands in the Mersurado-1 well,” commented Arthur Millholland CEO of COPL.“The targeted Santonian sand sequence and thickness intersected was in accordance with our seismic interpretation. The lack of hydrocarbons at this location where our seismic data presented attributes indicative of hydrocarbons will cause us to do additional work on the 3D seismic over the Block, and re-evaluate the other leads we have mapped on LB-13.”
