Mart Resources and its co-venturers, Midwestern O&G (Operator of the Umusadege field) and SunTrust Oil, reported encouraging initial test results from the first zone tested on the UMU-7 well located in the Umusadege field, onshore Nigeria.
The first test on the UMU-7 well was conducted on the XII sand, a 17 foot oil zone, which flowed at a stabilized rate of 2,459 barrels oil per day ("bopd") of 36 API gravity oil through 2 7/8 inch tubing on a 40/64 inch choke at a flowing tubing pressure of 180 psi. Basic sediment and water (BS&W) was 15% with gas/oil ratio of approximately 21 standard cubic feet per barrel.
Testing of the XIV sand is currently underway, with tests on the X and XVI to follow. Further updates will be provided on these sands once initial testing has been completed.
The UMU-7 well has been completed using a dual-tubing string configuration with the XVI and XIV sands completed in the 3 1⁄2 inch tubing string and the XII and X sands completed in the 2 7⁄8 inch tubing string. As a result of the completion technology used, the four zones that have been completed can be opened and closed at any time.
