88 Energy commences drilling of primary target interval at the Winx-1 well, North Slope of Alaska

88 Energy has advised the following in relation to its oil and gas operations on the North Slope of Alaska.

Highlights: Winx-1

Drilling of interval containing primary Nanushuk targets (@~4,500′) commenced 25th February (AK time): current depth ~2,640′

Western Leases – Winx-1 Exploration Well

The Winx-1 exploration well was drilled to ~2,500′ on the 20th February (AK time), with surface casing run and cemented successfully. The State supervised inspection of the Blow Out Preventer system was completed on the 24th February.

Drilling has now commenced in the intermediate section of the well, where the primary Nanushuk targets will be intersected.

Logging while drilling tools on the bottom hole assembly, combined with mud gas ratios and cuttings analysis, will provide initial insight into any potential hydrocarbon bearing intervals encountered during the drilling of the intermediate section. Additional data and analysis, including from wireline logging and potentially production testing will be required to provide more definitive results.

Winx-1 is located four miles east of the Horseshoe-1/1A well which significantly extended the highly successful Nanushuk topset play fairway to the south.

Winx-1 will target gross best estimate prospective oil resource of 400 million barrels of oil (144 million barrels net to 88E) across multiple stacked objectives, including the Nanushuk Formation, which is the primary target of the well.
