The UMU-12 horizontal well onshore Nigeria was recently completed with a 1,200-ft horizontal section in the VIII sand. The well was flowed back for clean-up and testing on various choke sizes for 80 hours, yielding a final test averaging 5,366 bbl/d on a 44/64-in. choke at a surface flowing pressure of 230 psi over a six-hour period, according to a news release.

Mart Resources Inc. and its co-venturers, Midwestern Oil and Gas Co.—operator of the Umusadege Field— and SunTrust Oil Co. provided the update on drilling and flow testing operations.

The API gravity of the oil is 26.4 degrees, with no sand, bottom sediment or water production.

The drilling rig has been moved to the UMU-13 well location and rig-up operations for the commencement of drilling of the UMU-13 well are nearing completion, the release said. UMU-13 is a vertical exploration well that is scheduled to be drilled to a target depth of 2,779 m (9,118 ft) and is intended to appraise the east prospect on the Umusadege license.
