Hardman Resources has finished testing at its Mputa-1 well in Uganda with the well flowing 1,120 barrels per day (bpd).
In a statement, the company said that the test results proved not only was the oil mobile, but that "the reservoir sands are capable of producing dry oil under natural flow at potentially commercial rates".
"The positive test results from Mputa are particularly important given that we map more oil in place in this resource than at Waraga. Natural flow from the reservoir at these pressures and temperatures are indicative that production rates could potentially be commercial," said Simon Potter, managing director and CEO, Hardman Resources.
The company is still waiting for laboratory confirmation, but it is believe that the oil flowed at Mputa is likely to be of similar origin to that found in the lower units of the Waraga-1 well.
Tullow Oil owns a 50 per cent share in the project.
