Nigeria: Mart Resources report encouraging initial test results

Mart Resources and its JV partners in the onshore Umusadege field, Midwestern Oil and Gas Company (operator) and SunTrust Oil Company, have reported encouraging initial results from the first zone tested.

The first test on the UMU-7 well was conducted on the XII(c) sand, a 17 ft oil zone, which flowed at a stabilised rate of 2,459 b/d of 36 API gravity oil through 2 7/8” tubing on a 40/64” choke at a flowing tubing pressure of 180 psi. Basic sediment and water (BS&W) was 15 per cent with a gas–oil ratio of approximately 21 scf per barrel.

Testing of the XIV sand is currently underway, with tests on the X and XVI(a) 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 (a) and XIV sands completed in the 3 1/2” tubing string and the XII(c) and X sands completed in the 2 7/8” tubing string. As a result of the technology used, the four zones that have been completed can be opened and closed at any time.
