Mart Resources, Inc. and its co-venturers, Midwestern Oil and Gas Company Plc. (Operator of the Umusadege field) and SunTrust Oil Company Limited, says that the UMU-3STH well, a horizontal side track of the original UMU-3 well, was drilled to target the oil bearing VI sand, which has average gross pay thickness in excess of 35 feet. The well was completed over a 787 foot horizontal section.
During initial flow testing, the well was tested at multiple choke settings ranging from 16/64 up to 40/64 over a 28 hour test period. In all tests, no sand production or water production was observed. The testing of the VI sand yielded an oil rate of 4,893 bopd of 26.6 API crude oil on a 40/64 choke setting and flowing tubing head pressure of 190 psig during a three hour flow test. Basic sediment and water (BS&W) was less than 0.5%. During the final test at choke setting of 40/64, the well was still showing signs of cleaning up, with gradually increasing flow rates. Therefore, the rate stated here is not defined as stabilized, but observed during cleanup and flow testing.
