Mahogany-2 well, offshore Ghana, Positive second reservoir test
Posted on July 11, 2008 – 3:34 pm | by vchris
10 July 2008 - Tullow Oil plc (“Tullow”) is pleased to announce results of a second successful flow test on the Mahogany-2 appraisal well, which is part of the Jubilee field offshore Ghana.
In June this year the Lower Mahogany reservoir was successfully tested over a 17-metre interval. Following completion of this test, partners took the decision to perform a second flow test – this time on the Upper Mahogany reservoir.
This latest test was conducted over a 23-metre perforated interval, representing approximately 40% of the oil-bearing pay of the Upper Mahogany reservoir. The interval flowed at a rate of 4,448 bopd of 39˚ API oil and approximately 5.1 mmscfd of associated natural gas on a 36/64-inch choke.
In both tests, the reported flow rates were restricted by both equipment and facilities. These test results have provided important additional reservoir data in respect of this previously untested interval and confirm that Jubilee production wells should be capable of flowing at rates in excess of 20,000 bopd when completed with 5 ½-inch tubing.
Commenting today, Aidan Heavey, Chief Executive, said:
“The result of the second test on Mahogany-2 continues to demonstrate the high quality of the Jubilee field and supports the partners’ fast track development approach. Allied to encouraging progress on development planning, facilities tendering and gas commercialization this latest result means that plans to sanction the development of the Jubilee field later in 2008 remain firmly on schedule.”
