88 Energy Limited (LON:88E, ASX:88E) is on track to test its latest Alaska well late next month or early July after successfully cementing in place the production liner.
Icewine-2, which has targeted the potentially prolific HRZ shale, will begin the stimulation phase of the programme in the third week of June.
Managing director Dave Wall said: "The Alaska team have successfully completed the Icewine-2 well on schedule, after an effective adjustment to the completion plan, post the initial unsuccessful attempt to set the production liner.
“Everything is now lining up for execution of the main stimulation operation, with flow testing of the HRZ on target for late June."
Icewine-2 is expected to provide further insight into the scale of the HRZ shale discovery.
Significantly, it will be fracked and flow tested to determine the commercial potential of the shale, which is estimated to hold billions of barrels of oil.
