This announcement contains inside information

88 Energy Limited

Merlin-2 Appraisal Well Location Selected


· Merlin-2 location selected from the three locations initially permitted for the appraisal program

· Target drilling location situated east and downdip of Merlin-1

· Merlin-2 well location expected to display thicker reservoir sections and higher permeability / porosity sands, targeting 652 million barrels of oil1,2 with geological chance of success of 56%

· Remaining two locations, together with Harrier-1, are permitted and can be drilled at a later stage

· Production test for the Merlin-2 well planned subject to results of wireline program

· Permitting and planning of Merlin-2 is at an advanced stage, with the benefit of learnings from Merlin-1

88 Energy Limited (ASX:88E, AIM:88E, OTC:EEENF) (88 Energy or the Company) is pleased to announce that the Merlin-2 well location has now been selected, from three initially permitted locations.  The Merlin-2 well location, scheduled for drilling in February 2022 using the recently contracted Arctic Fox rig, is located east and downdip of the successful Merlin-1 well. This location is expected to encounter thicker reservoir sections and higher permeability / porosity sands.

The Merlin-2 appraisal well is planned for a Total Depth of 8,000 feet, and is targeting 652 million barrels of oil 1,2   in the highly prospective N18, N19 and N20 targets that were encountered in the successful Merlin-1 well (drilled in March 2021 to a depth of 5,267 feet), which demonstrated the presence of oil in these multiple stacked sequences in the Brookian Nanushuk Formation.

The remaining two locations permitted, together with the permitted Harrier-1 location, can be drilled in future years as part of an extended drilling program to assess the full potential of the Project Peregrine acreage.

A production testing program for the Merlin-2 well has been designed and will be on standby during initial wellsite operations. The production test is contingent upon the wireline program results, in particular the MDT results, as well as government approvals. The program and length of the test will be subject to operational, funding and weather window considerations.

Permitting and planning for the Merlin-2 well remains on track for scheduled spud in February 2022.

F urther details on the upcoming operations at Merlin-2, and the Company's other activities, are contained in the Company's latest corporate presentation, which is available on 88 Energy's website at



1 Cautionary Statement: The estimated quantities of petroleum that may be potentially recovered by the application of a future development project relate to undiscovered accumulations. These estimates have both an associated risk of discovery and a risk of development. Further exploration, appraisal and evaluation are required to determine the existence of a significant quantity of potentially movable hydrocarbons.

About Project Peregrine


Project Peregrine is located in the NPR-A region of the North Slope of Alaska and encompasses approximately 195,000 contiguous acres. It is situated on trend to recent discoveries in a newly successful play type in topset sands in the Nanushuk formation. 88 Energy has a 100% working interest in the project.


The Merlin-1 well was spudded in March 2021 with drilling operations completed in April 2021. Interpretation of results was completed in August 2021 with post well evaluation successfully demonstrating the presence of oil in N20, N19 and N18 targets, with 41 feet of net log pay across the three reservoir intervals noted and geochemical analysis determining the oil to have an estimated API gravity between mid-30 to low-40 API (light oil).


A second well, the Merlin-2 appraisal well, is planned to be drilled in Q1 2022 as a follow-up well to the Merlin-1 exploration well.  Merlin-2 is targeting a net entitlement mean Prospective Resource of 652 million barrels (unrisked)1,2.

Independent oil and gas reservoir evaluation consultancy, ERCE Australia Pty Ltd (ERCE), con ducted an updated assessment of the Project Peregrine prospective resources post the Merlin-1 well results.  The updated prospective resource estimates and risking assessments for Project Peregrine are noted below.

Prospects Total



1. The Prospective Resources presented here are the result of a risked probabilistic aggregation of the individual stacked prospective layers in each prospect; the success case estimates present the distribution of possible outcomes in the event that at least one prospective layer is successful.

2. Unrisked mean total is not representative of the expected total from the four prospects and assumes a success case in all four wells.

3.   COS represents the geological chance of success of at least one of the stacked layers which comprise each prospect. This excludes phase risk which ERCE has estimated to be 70% oil (30% gas). The Prospective Resources have also not been adjusted for the chance of development, which is estimated by 88 Energy to be 60% (including phase risk), ERCE sees this as reasonable based on the data available. Quantifying the chance of development (COD) requires consideration of both economic contingencies and other contingencies, such as legal, regulatory, market access, political, social license, internal and external approvals and commitment to project finance and development timing. As many of these factors are out-with the knowledge of ERCE they must be used with caution.

4. Gross Prospective Resources include off-block volumes over which 88 Energy has no mineral rights. Net working interest Prospective Resources are based on the on-block volumes and 88 Energy's 100% working interest. Net entitlement Prospective Resources are the net working interest Prospective Resources less royalties payable to others. The net entitlement interest to 88 Energy is calculated as 84.7% of net working interest after deduction of state royalty (12.5%) and overriding royalty interests (1.3%and 1.5%).
