88 Energy Ltd. has mapped the recently identified Upper Slope Fan System (Upper SFS) across its Project Pheonix acreage on the North Slope of Alaska. The data will be used for subsequent stimulation and flow test operations.
Seismic interpretation and log correlation has revealed that the Upper SFS reservoir is more extensive than originally mapped, correlating over 4 miles to strong shows in the Icewine-1 well previously attributed to be part of the lower SMD-A package (OGJ Online, Apr. 11, 2023).
Resources in this reservoir are not currently included in the company’s resource estimates as they have yet to be assessed. The Upper SFS target remains an untested reservoir in nearby offset wells. The company described the quality and strength of shows recorded during the drilling and logging of Hickory-1 as still among the best it has witnessed to date. Moreover, post-well geochemical analysis of Hickory-1 sidewall core data indicates fluid maturity to be in the early-peak oil window.
Simulation models have been built for each of the target intervals in Hickory-1, with the objective of ensuring a successful stimulation and flow test in each zone. Pantheon Resources reported flow rates of 50-100 bo/d from vertical wells and intervals in the adjacent northern acreage. These vertical test results, although modest, provide critical information in understanding the reservoirs and allow the design of long, horizontal wells that would be employed during development.
Post-well analysis and flow test modelling of the Hickory-1 reservoirs provide accurate design of completion fluids and string necessary for flow test operations. Sourcing and procurement of these long lead items is underway with operations scheduled for early first quarter 2024. Permitting is on track with the Alaskan state authorities, and All American Oilfield LLC’s recently upgraded Rig 111 drilling-workover module has been secured for the flow test program.
88 Energy holds 75% interest and is operator of the Project Phoenix area.
