Hickory-1 Pre-Flow Test Operations on Track

Highlights

· Flow test permitting completed with the approval of the AOGCC frac sundry permit received.

· Operations commenced with rig commissioning and ice pad construction underway.

· Hickory-1 flow test operations on track with mobilisation of the All American Rig-111 and operations equipment scheduled for mid-February 2024.

88 Energy Limited (ASX:88E, AIM:88E, OTC:EEENF) (88 Energy or the Company) is pleased to report that the Hickory-1 well ice pad construction has commenced and that pre-flow test operations are on schedule, with all requisite permits and approvals received from the relevant authorities including the recently received Alaska Oil and Gas Conservation Commission (AOGCC) frac sundry permit. The Hickory-1 well is located within 88 Energy's Project Phoenix acreage, directly adjacent to the Trans-Alaska Pipeline System and the Dalton Highway.

Mobilisation of All American Rig-111 to the Hickory-1 well location is scheduled to commence mid-February 2024, together with equipment and services relating to the well flow testing operations. The Hickory-1 program remains on track for commencement of flow testing operations shortly after mobilisation of the rig is completed.

Testing operations will focus on the two primary targets, the SFS and the SMD zones. These two zones possess, in aggregate, a multi-hundred million barrel oil prospective resource (mean, unrisked)1,2,3.

The Upper SFS reservoir is set to be flow tested first. This zone has not previously been flow tested at Project Phoenix or on adjacent acreage. This will then be followed by targeted testing of the SMD-B reservoir.

Each zone is set to be independently isolated, stimulated and flowed to surface using nitrogen lift to assist in an efficient clean-up of the well. Each of the two planned flow tests is scheduled to take approximately ten days to complete, with perforation, completion-running and stimulation expected to take four days, followed by a clean-up and flow period of up to four days and a pressure build up and downhole fluid sampling program of up to 2 days.

The Company will provide a further update upon commencement of the flow test operations.
