UK onshore-focused Egdon Resources reported Tuesday that gas has flowed from a third interval in the Wressle-1 well on the PEDL180 license in east Lincolnshire, England.
Egdon said that test operations have been completed on the first set of perforations in the Penistone Flags reservoir – the last of three hydrocarbon-bearing zones identified in the well. The Penistone test produced gas at restricted flow rates of up to 1.7 million cubic feet per day, with associated oil of up to 12 barrels per day.
Gas flow rates were constrained by the equipment and flaring limits imposed by the environmental permit for the well. Gas and oil are of good quality, with the oil having a gravity of 35-degree API, Egdon said.
Egdon said a further test will now be undertaken to evaluate the gas-oil and oil-water contacts in the Penistone interval by perforating the formation deeper in the section.
Egdon Managing Director Mark Abbott commented in a company statement:
"We are very encouraged by the early test results from the Wressle-oil and gas discovery. All three zones tested have produced hydrocarbons to surface, with a restricted flowrate of 1.7 million cubic feet per day from the Penistone Flags, free-flowing rates of up to 182 barrels of oil per day and 0.46 million cubic feet per day from the Wingfield Flags and 80 barrels of oil per day from the Ashover Grit.
"We now look forward to the results of our work to identify the location of the expected oil leg in the Penistone and to seeing what oil rates can be achieved with pumping of the Ashover Grit. We will now be working hard to integrate these test results into our models of the Wressle discovery to enable us to update our resource assessment and to plan for the development of the field where we will look to maximize value from both the oil and gas."
