  • Dual success at Hickory-1 with the flowing of light oil from the USFS and SMD reservoirs.
  • Post flow test studies to commence including the securing of additional Contingent Resource estimates.
  • Commercialisation options to be considered in parallel, including farm-out to a strategic development partner and/or early and a capital-lite development.

88 Energy has provided a further update and information in relation to the successful flow test results announced on 2 April and 15 April 2024, from the Company's Hickory-1 discovery well, located in Project Phoenix on the North Slope of Alaska (88 Energy ~75% WI owner).

As announced, light oil was recovered from both the USFS and SMD-B reservoirs, with key details from each test summarised below, and to provide additional clarification on the reported results.

Upper SFS (USFS) Flow Test Results

  • A 20ft perforated interval in the Upper SFS reservoir was stimulated via a single fracture stage of 241,611 lbs proppant volume.
  • The well was cleaned-up and flowed for 111 hours in total, of which 88 hours was under natural flow back and 23.5 hours utilising nitrogen lift. Of the 88 hours of natural flow back period included ~78 hours of clean up with trace oil recovered during this time, and a period of ~ 10.5 hours of established production.
  • During the established production period of 10.5 hours the well produced at an average oil flow rate of ~ 42 bopd during the natural flow back period, producing a total of ~ 19bbls of oil. Approximately 6bbls of oil was also recovered during the clean up / non-established production period.
  • The USFS test produced at a peak flow rate of over ~70 bopd, which was an instantaneous rate calculated during flow back period via an oil tank volume measurement of 1.55 bbls over a 30 minute period.
  • Multiple oil samples were recovered with measured oil gravities of between 39.9 to 41.4 API (representing a light crude oil).

SMD-B Flow Test Results

  • A 20ft perforated interval in the SMD-B reservoir was stimulated via a single fracture stage of 226,967 lbs proppant volume.
  • The well was cleaned-up and flowed for 84 hours in total under nitrogen lift, with ~68 hours of clean up prior to the flowing of oil to surface, with the well flowing oil over ~16 hour period.
  • The well produced at an average oil cut of 4% following initial oil to surface, with instantaneous rates observed during the 16-hour period varying as the well continued to clean up at managed fluid flow rate of ~170 bbls/d with a calculated total volume during the flow back period following establishment of oil cut of ~4 bbls of oil.
  • The SMD-B test produced at a calculated peak flow rate of ~50 bopd, which was an instantaneous rate calculated during the flow back period via a measurement of observed oil cut and fluid flow rates.
  • Multiple oil samples were recovered with measured oil gravities of between 38.5 to 39.5 API (representing a light crude oil).

Forward Plan

Following the successful flow testing at the Hickory-1 discovery well, 88 Energy will be focused on:

  • Completing post-well testing and analysis at Hickory-1;
  • Securing a contingent resource for the SFS and SMD reservoirs;
  • Commencing a formal farm-out process to attract a high-quality new partner to fund the next stage of appraisal and development; and
  • Advance planning and design of an early stage production system.

The Company looks forward to updating shareholders on the post test analysis.
