Hickory-1 Surface Hole Completed

Highlights

·   Hickory-1 surface hole successfully drilled to 3,570 feet, cased and BOP system tested successfully.

·   Operations progressing with Nordic Calista's Rig-2 now preparing to drill ahead.

88 Energy Limited (ASX:88E, AIM:88E, OTC:EEENF) (88 Energy or the Company) is pleased to report that the Hickory-1 surface hole was successfully drilled to 3,570 feet, the surface casing installed and cemented and the Blow Out Preventer (BOP) system tested successfully.

Nordic Calista's Rig-2 is now preparing to drill ahead, with the Hickory-1 exploration well expected to intersect the three primary SMD targets, before drilling ahead into the secondary SFS and BFF reservoirs targets. The KUP reservoir is a tertiary target and will be drilled subject to remaining time in the season, borehole conditions and other technical considerations.

The Company anticipates the primary and secondary target zones to be intersected within the next two weeks, before determining whether to drill ahead to the tertiary target and reaching permitted Total Depth (TD) of approximately 12,500 feet.

Logging while drilling and mudlogging are set to provide initial indications as to the prospectivity of the target zones at the Hickory-1 location. A sophisticated, targeted wireline logging program is planned to be run after reaching TD, which includes side wall cores (both pressurised and non-pressurised), triple combo, dielectric scanner and Nuclear Magnetic Resonance.

The wireline logging program is expected to take approximately five to seven days to complete. It is designed to gather extensive data which will be used to optimise the planned Hickory-1 flow test program scheduled for the 2023/24 winter season (subject to well results).

The Company will provide further updates subsequent to Hickory-1 achieving TD.

About Project Phoenix

Project Phoenix (88E 75.2% WI) is located on the central North Slope of Alaska and encompasses approximately 82,846 gross acres. It is situated on-trend to recent discoveries by Pantheon Resources Plc (LSE: PANR) in multiple, newly successful play types across top, slope and bottom-set sands of the Mid Schrader Bluff, Canning and Seabee formations. Independent mapping has demonstrated that these plays extend into the Phoenix acreage.

Figure 1: Project Phoenix lease area, including mapped play fairways, Franklin Bluffs 3D area and planned Hickory-1 well location.

Project Phoenix holds an estimated unrisked total of 647MMbbl of conventional prospective oil resources (mean unrisked, net to 88E), independently assessed by Lee Keeling and Associates (LKA) in Q3 2022 (see 88E ASX release dated 23 August 2022). The acreage has been significantly de-risked by the recent Pantheon drilling and flow tests on their adjacent acreage to the North, coupled with data from Icewine-1 well logs (encountered 380 ft of net oil pay within SMD sands) and a modern 3D seismic data set (FB3D).

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.

6.    Please refer to ASX announcement dated 23 August 2022 for further details in relation to the prospective resources estimate and associated risking with Phoenix.

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