The company said that gas oil ratio was 34 standard cubic feet per barrel of oil at a flowing wellhead pressure of 295 psi, which is in line with the company’s estimated rate.
The Mus (1627mt to 1667mt) section of the Jurassic will be re-tested next, followed by the Sargelu (1450mt to 1510mt), which will then also be configured for long term production testing.
John Gerstenlauer, COO for Gulf Keystone, said: “I am encouraged by this verification of the flow capacity of the Butmah formation. This test represents another step in our efforts to confirm and define the magnitude of the Shaikan discovery.
“The well has now demonstrated an aggregate flow capacity of over 20,000bopd from just a fraction of the total prospective interval. I look forward to further testing and also to commercial oil sales from the long term test of the Sargelu, commencing later this year.”
