Australian operator 88 Energy Limited has updated the market on its Alaskan Project Icewine.
The northern slope well is currently flowing back naturally at 55 barrels per day following a shut in to allow a pressure build up.
Flow testing re-commenced on August 31 and is ongoing.
he well was stimulated in two stages over a gross 128 foot vertical interval in the HRZ shale formation, from 10,957-11,085ft TVD, using a slickwater treatment comprising 27,837 barrels of fluid and 1,034,838 pounds of proppant.
Wellhead pressure built to 3,500psi during shut-in and has dropped to 106psi since flowback commenced and is now declining very slowly with a relatively constant flowback rate of 55 barrels per day.
As at 9.30 September 9 (AK time), a decision was made to run the flowback through the test separator due to minor gas indications being evident.
To date the rate of flow has been unstabilised at between 2 and 4 mcf per day made up of 76% hydrocarbons, 20% atmospheric gases and 4% inorganics. The produced hydrocarbons comprise 93% methane with 7% heavier fractions.
In a statement the company said: “The current flowback procedure remains early stage with only 19.0% of the frac fluid retrieved.
“The gas observed so far is not considered representative of the potential rate or composition of hydrocarbon in the reservoir.
“It is interpreted that additional frac fluid needs to be removed in order to achieve a representative result. A decision will be made on the most appropriate strategy to accomplish this within the next two weeks.”
