88 Energy (ASX: 88E) has significantly boosted its South Prudhoe prospective resource estimates by approximately 35%.
The total gross unrisked 2U Prospective Resources for South Prudhoe now stand at 768.9 MMbbls, with 640.7 MMbbls net to 88 Energy.
This upgrade includes the introduction of a maiden Brookian resource estimate for the North-West Hub, totalling 181.5 MMbbls gross (151.2 MMbbls net).
Concurrently, the Ivishak estimate for the North-West Hub was upgraded by approximately 44% to 69.9 MMbbls gross (58.2 MMbbls net).
Augusta-1 Drilling Advancements
The company has also secured the Nordic-3 rig for the 2027 winter drilling season for its high-priority Augusta-1 well, signalling strong operational progress.
This rig is known to 88 Energy, having been used in previous North Slope campaigns in 2019 and 2020.
The Augusta-1 well is designed to test multiple stacked reservoir intervals, including Ivishak, Kuparuk, and Brookian formations.
This multi-zone target has the potential to test up to 133.7 MMbbls gross unrisked resources, or 111.4 MMbbls net to 88 Energy.
Operational and Funding Progress
Securing the Nordic-3 rig is a critical operational milestone, helping to de-risk the Q1 2027 drilling campaign.
88 Energy continues to advance its farmout-led funding strategy for Augusta-1, with existing cash reserves underpinning these efforts.
Further regulatory administrative processes for additional exploration tracts are expected to be finalised in the second half of 2026.
This will help pave the way for future resource conversion and exploration activities.
Context: Alaska North Slope Focus
88 Energy's strategic direction, as highlighted in previous annual reports, has been firmly reset towards a concentrated portfolio on the Alaskan North Slope.
This region is central to the company's exploration efforts.
The company's strategy involves leveraging new acreage acquisitions and establishing partnership funding structures, such as the farm-out agreement with Burgundy Xploration for Project Phoenix.
This approach allows 88 Energy to focus on infrastructure-adjacent, lower-risk exploration and appraisal opportunities.
Outlook
88 Energy's resource upgrade and rig contract for Augusta-1 significantly enhance its exploration profile in Alaska.
While prospective resources remain unrisked, the company is making tangible progress on operational catalysts, though successful farmout and funding remain critical for drilling execution.
