Project Icewine East: Maiden Independent Prospective Resource Estimate of 1.03 Billion Barrels*

Highlights

   --     Maiden Independent Prospective Resource estimate completed at Project Icewine East. 

-- Total estimated Prospective Resource of 1.03 billion barrels (Bnbbls) of oil* recoverable from multiple reservoir zones.

-- Independently certified prospective resource estimate prepared by Lee Keeling & Associates, Inc., a US based independent expert petroleum and engineering firm.

-- Substantial oil volumes noted across all mapped play fairways, in particular the Seabee - Lower Basin Floor (BFF) and the Shelf Margin Delta (SMD) reservoirs.

   --     88 Energy Limited is intending to drill an exploration well on the acreage in 2023. 

88 Energy Limited (ASX:88E, AIM:88E, OTC:EEENF) ( 88 Energy or the Company ) is pleased to report a maiden, independently certified Prospective Resource estimate of 1.03 Bnbbls of oil (gross mean, unrisked) for Project Icewine East (75% net working interest).

Significant prospective resources have been estimated across all the recently mapped Shelf Margin Delta ( SMD ), Slope Fan System ( SFS ), Basin Floor Fan ( BFF ) and Kuparuk ( KUP ) play fairways on the Icewine East acreage. Importantly, these are mapped as the same Brookian / Beaufortian reservoirs that nearby Pantheon wells - Alkaid-1, Talitha-A and Theta West-1 - have flowed 35 to 40 API oil. Pantheon's previous well tests have also confirmed reservoir deliverability of light, sweet oil (see Pantheon releases of 7 February, 21 February and 24 March 2022), which 88 Energy believes is positive for the prospectivity of the adjacent Icewine East acreage.

The maiden Independent Prospective Resource Report was completed by Lee Keeling and Associates, Inc. ( LKA ). The initial total prospective resource follows a period of review of an extensive data suite that included seismic data, well logs from Icewine-1 and nearby wells adjacent to the Icewine East acreage, recent petrophysical analysis and mapping. LKA are an independent US based expert petroleum geoscience and engineering consulting firm who have significant and recent experience in providing resource estimates globally as well as more specifically in Alaska.

* Gross mean unrisked prospective resource

Managing Director, Ashley Gilbert, commented:

"This maiden, independently certified 1.03 Bnbbls of oil resource estimate is a great result for 88E and its shareholders. Resources of this magnitude present our shareholders with significant upside potential and opportunity, which is why we continue to focus on our Alaskan portfolio and believe significant value exists in our Icewine East acreage.

Importantly, it is worth noting that the Icewine East acreage has been significantly de-risked by the recent Pantheon drilling and flow tests on their adjacent acreage, as well as data from the Icewine-1 well logs, and more recently the leased Franklin Bluffs 3D data set. This work substantially increases our confidence in unlocking the potential of the Icewine East acreage and is by far, the most compelling data suite the Company has analysed ahead of drilling any well.

Full interpretation of the recently licensed FB3D data is ongoing, including AVO analysis, to define 'sweet spots' for each play and determine optimal future exploration and appraisal drilling locations, the first of which is planned for 2023."

1. 88 Energy net resources have been calculated using a 75.227% working interest and a 16.5% royalty.

2. The unrisked means, which have been arithmetically summed, are not representative of expected total from the prospects and implies a success case in all reservoir intervals. 88 Energy cautions that the arithmetically summed 1U estimate may be a conservative estimate and the arithmetically summed 3U estimate may be optimistic when compared to a statistical aggregation of probability distributions.

3. COS represents the geological chance of success as assessed by 88 Energy and reviewed and endorsed by LKA.

4. Prospects are subject to a phase risk (oil vs gas). Chance of oil has been assessed as 100% for all targets except for the Kuparuk Formation which has been assessed as 70%. Phase risk has not been applied to the unrisked numbers.

5. The Prospective Resources have not been adjusted for the chance of development. Quantifying the chance of development (COD) requires consideration of both economic 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 outside the knowledge of LKA they must be used with caution.

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.

The data used to compile the independent prospective resource report includes reprocessed 2D seismic data, basin modelling, petrophysical analysis of publicly available wells and historical geological records. The data was compiled and interpreted by 88E and was reviewed, validated and in some cases modified independently by LKA.

LKA's methodology for determining Prospective Resources for Project Peregrine

LKA has determined Prospective Resources by examining the areas of consistent bright amplitude that were mapped by independent consultants to 88E, Jordan and Pay, using the reprocessed 2D seismic data within the Icewine East area. Parameters including potential pool area and thickness, porosity, hydrocarbon saturation, oil expansion and recovery factor were estimated on a probabilistic low, mid and high basis. The Prospective Resources distributions were then aggregated into four (4) prospects, on the basis that one (1) well could effectively test all the mapped prospective intervals. The unrisked prospective resources estimates (and associated geological chance of success) were modelled using Monte-Carlo analysis on the assumption there was no economic minimum and that volumes and risks of each of the prospective intervals within each prospect were independent.

The Prospective Resources have not been adjusted for phase risk or chance of development. 88 Energy and LKA have considered the chance of discovering oil over gas to be 100% for all targets except for the Kuparuk Formation which was assessed to be 70%. Chance of development has not been estimated.

Please refer to the disclaimers attached as Schedule 1 of this ASX release for more information on the prospective resource report.

About Project Icewine

Project Icewine is located on the central North Slope of Alaska and encompasses approximately 185,320 net acres. It is situated on-trend to recent discoveries in multiple, newly successful play types in topset and bottom-set sands of the Schrader Bluff and Seabee formations. 88 Energy has a 75.227% working interest in the Project.

Icewine East and West acreage positions hold an estimated conventional total 2.8 billion BOE* of prospective resource, independently assessed.

88 Energy has conducted 2D and 3D seismic acquisitions and drilled three exploration wells in the acreage, including the Charlie-1 discovery well in Q1 CY2020.

Project Icewine East - Total Prospective Resource of 1.03 Billion Barrels of Oil*

Icewine East resource estimate completed in Q3 2022. Acreage de-risked by historical exploration wells and near-field exploration drilling and flow tests recovering light oil, as well as recently leases Franklin Bluffs 3D ( FB3D ).

The FB3D will assist through subsequent analysis, including AVO analysis and simultaneous seismic inversion, in defining 'sweet spots' for each play and hence determine optimal drilling location for a planned well in 2023.

Project Icewine West - Total Prospective Resource of 1.8 Billion Barrels of Oil Equivalent*

Project Icewine West has previously been independently assessed as having a total gross mean unrisked prospective resource of 1.77 billion BOE**. The Charlie-1 discovery well, drilled in 2020, recovered hydrocarbons during wireline operations.

SCHEDULE 1

Disclaimers:

Cautionary Statement for Prospective Resource Estimates - With respect to the Prospective Resource estimates contained within this report, it should be noted that the estimated quantities of gas that may potentially be recovered by the future application of a development project relate to undiscovered accumulations. These estimates have an associated risk of discovery and risk of development. Further exploration and appraisal is required to determine the existence of a significant quantity of potentially moveable hydrocarbons.

Hydrocarbon Resource Estimates - The Prospective Resource estimates for Project Icewine East presented in this report are prepared as at 9 August 2022. The Prospective Resource estimates are quoted on an unrisked basis together with the geological chance of success for each prospect. The unrisked mean total presented in the table is not representative of the expected total from the 4 prospects and assumes a success case in all reservoir intervals. 88 Energy and LKA have considered the chance of discovering oil over gas to be 100% for all targets except for the Kuparuk Formation which was assessed to be 70% . Chance of development has not been estimated. 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 outside the knowledge of LKA they must be used with caution.

Government Royalty and Overriding Royalty Interests - The Project Icewine East leases ("Leases") are situated in the State Lands of the North Slope of Alaska and are administered by the Alaskan Department of Natural Resources - Oil and Gas Division (DNR). All leases issued by DNR are subject to a royalty and 88E's Leases are subject to a 12.5% government royalty. In addition, the Leases are subject to an overriding royalty of 4.0% payable to non-related parties of the Company. The net economic interest to 88E has therefore been calculated as 62.81% and the Net Entitlement Prospective Resources have been adjusted to reflect this.

Competent Person Statement Information - In this report information relating to hydrocarbon resource estimates have been supplied by LKA, and the company has stated in the Report that it has been prepared in accordance with the definitions and guidelines set forth in the Petroleum Resources Management System, 2018, approved by the Society of Petroleum Engineers and have been prepared using probabilistic methods.

Definitions and Glossary of Key Terms:

SPE definition: Prospective Resource

Prospective resources are estimated volumes associated with undiscovered accumulations. These represent quantities of petroleum which are estimated, as of a given date, to be potentially recoverable from oil and gas deposits identified on the basis of indirect evidence but which have not yet been drilled. This class represents a higher risk than contingent resources since the risk of discovery is also added. For prospective resources to become classified as contingent resources, hydrocarbons must be discovered, the accumulations must be further evaluated and an estimate of quantities that would be recoverable under appropriate development project(s) prepared.
