Tullow
Oil Announces Successful Flow Test on Jubilee Field
07-11-2008
Tullow Oil plc announces 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 - 6 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 'b0 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 ˝'bd-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.”
