Oil and gas operator Oilexco said yesterday it had successfully flow-tested gas condensate at significant rates from its Moth discovery in the UK North Sea.
It said this followed the company’s announcement on June 26, confirming a significant dual zone oil and gas-condensate discovery at Moth, in central North Sea block 23/21.
Oilexco said the test flowed gas at an average rate of 20.3million cubic feet (mcf) with 2,110 barrels per day of condensate: 5,493 barrels of oil equivalent per day (boepd) in total.
The maximum flow rate achieved during the test was 24.4mcf and 2,460 barrels of condensate (6,526boepd). It added that flow rates were severely restricted by the equipment used for the test and the working temperatures and pressures encountered.
Oilexco said its findings suggested that the Moth well could be capable of 44mcf of gas and 4,400 barrels of condensate (11,800boepd) with a properly sized production string.
Chief executive Arthur Millholland said: “We are very pleased with the results of the Moth well, which has the potential to become a significant producing asset for the company.
“We will now evaluate the timing of additional appraisal of the Moth structure and development options in the near future with our co-venturers.
“Our objective at Moth is the same as our other exploration successes in the North Sea: an effective and efficient appraisal programme followed by early development to rapidly commercialise our expansive portfolio.”
The Canadian oil and gas exploration and production company has been the most active driller in the UK North Sea for four years.
