RE: Charlie 1 North Slope well results mixed; 88 Energy pursues farmout for HRZ unconventional14 Apr 2020 22:32

Seabee not intersected optimally
In the Seabee formation (apron/fan play) an unsuccessful attempt was made to take a sample from what 88 Energy named the lower Lima prospect, being the better of the two Lima targets, but there was insufficient reservoir quality, the company said.
However, given that the Seabee was not intersected optimally, there still may be potential for higher quality reservoir at a different location, 88 Energy reported April 7. Also, the company said, a 220-foot interval had been encountered in Malguk 1 in the lower Lima, with up to 60% oil saturation and an average porosity of 11%.
Prior to drilling 88 Energy told investors the stacked Seabee targets in the Lima prospects were considered tertiary due to higher risk associated with reservoir quality at the Charlie 1 location. In well planning the company had been most interested in getting a better intersect on the primary Torok targets.
88 Energy had estimated the mean prospective oil resource in the Seabee Lima targets was 376 million barrels of oil gross mean (113 million barrels net mean to the company).
Mud gas seen while drilling in the Seabee “indicated that the hydrocarbons at this horizon were heavier than those in the Torok and this was the horizon where ‘live oil’ was observed across the shakers” in the nearby Malguk 1 well.
“Excellent vertical seismic profile, or VSP, data was obtained in the well, which will now be used in conjunction with other log data and the existing 3D seismic, to remap the targets. Sidewall core analysis will also help determine where improved reservoir is likely to exist,” 88 Energy said.
Premier withdraws from JV
Premier decided to exit the project because well results did not meet its expectations, but 88 Energy said the $23 million that Premier paid to farm into the project was in the joint venture’s bank account, noting well costs remained within the expected budget, so no additional costs will be incurred.
With Premier’s withdrawal 88 Energy’s working interest will increase to 75% in Area A of the Icewine project, including the gas condensate discovery, Charlie 1, and Malguk 1.
Charlie 1 plugged and abandoned
The well was plugged and abandoned rather than suspended because further analysis was needed to determine whether such a high gas content discovery could be commercialized on the North Slope, the company said, noting stimulation and testing was not possible because of “the different phase of hydrocarbons encountered along with the lack of time in the remaining winter drilling season.”
Other factors included uncertain access to some of the people required in the event of “unforeseen circumstances/emergency situations in light of the COVID-19 pandemic” and the potential of early break-up, which could strand the drilling rig, Nordic Rig 3, on the wrong side of the Kuparuk River at significant cost to the JV.
