Icewine#2 Operations Update
88 Energy Limited (“88 Energy”, “the Company”, “Operator”) (ASX, AIM: 88E) is pleased to provide an update on Project Icewine, located onshore North Slope of Alaska.
- Flowback continues with ~13% of stimulation fluid recovered
Icewine#2 Operations Update
Flowback commenced on the 19th June from stage 2 (upper zone). Approximately 8% of total stimulation fluid volume was recovered until it became apparent, due to rate and pressure observations, that the upper zone was likely in communication with the lower zone. Consequently, a decision was made to drill out the plug between the upper and lower zones. No increase in pressure was observed, confirming that the two zones are in effective communication. Trace hydrocarbons were encountered whilst flowing back the upper zone prior to drilling out the plug and, as expected, the flow rate returned to 100% stimulation fluid once the two zones were flowed back together.
Flowback, currently comprising 100% stimulation fluid, is continuing. Percentage of fluid recovered to date is ~13% of the total fluid pumped. It is estimated that up to 30% of the stimulation fluid will need to be recovered before hydrocarbons will be released from the reservoir.
The forward plan is to monitor pressure and flow rate and continue to draw stimulation fluid off the reservoir. Artificial lift, using nitrogen or swab cups, may be introduced at some stage to increase the rate of draw down of fluid. If pressure becomes too low it is possible that operations will necessitate a shut-in to allow fluid to ‘soak’ and pressure to build up. This ‘soaking’ is not uncommon in other shale plays as it allows stimulation fluid to be absorbed into the reservoir and can result in lower required fluid flowback before onset of hydrocarbon flow.
Further updates will be made as and when appropriate throughout the testing program.
Managing Director, Dave Wall, commented: “We continue to monitor pressure and flowback of stimulation fluid whilst we wait for hydrocarbons to be released from the reservoir. Given that we are breaking new ground in relation to the HRZ formation, we need to establish the conditions under which the hydrocarbon cut will return and then increase.
The stimulation was executed precisely as per plan with over one million lbs of proppant placed into the formation. A little patience is now required as we give the rocks time to show us what they can deliver.”

Project Icewine Overview
In November 2014, the Company entered into a binding agreement with Burgundy Xploration (BEX) to acquire a significant working interest (87.5%, reducing to 77.5% on spud of the first well on the project) in a large acreage position on a multiple objective, liquids rich exploration opportunity onshore Alaska, North America, referred to as Project Icewine. In June 2016, the gross acreage position was expanded to 271,119 contiguous acres (210,250 acres net to the Company). In December 2016 the Company successfully bid on additional acres. On award the Project Icewine gross acreage position will be further expanded to ~690,000 contiguous acres (~400,000 acres net to the Company assuming all rights are taken up).
The Project is located on an all year operational access road with both conventional and unconventional oil potential. The primary term for the State leases is 10 years with no mandatory relinquishment and a low 16.5% royalty.
The HRZ liquids-rich resource play has been successfully evaluated based on core obtained in the recently completed (December 2015) Icewine #1 exploration well, marking the completion of Phase I of Project Icewine. Phase II has now commenced, with drilling at the follow-up appraisal well, Icewine#2, commencing early 2Q2017. Production testing is scheduled to occur in mid-2017.
Significant conventional prospectivity has also been identified on recently acquired 2D seismic across the project acreage.
Cautionary Statement: The estimated quantities of petroleum that may be potentially recovered by the application of a future development project relate to undiscovered accumulations. These estimates have both an associated risk of discovery and a risk of development. Further exploration, appraisal and evaluation are required to determine the existence of a significant quantity of potentially movable hydrocarbons.
Generous exploration incentives are provided by the State of Alaska with up to 35% of net operating loss refundable in cash.
The primary objective is an untested, unconventional liquids-rich shale play in a prolific source rock, the HRZ shale (Brookian Sequence), that co-sourced the largest oil field in North America; the giant Prudhoe Bay Oil Field Complex. Internal modelling and analysis indicates that Project Icewine is located in a high liquids vapour phase sweetspot analogous to those encountered in other Tier 1 shale plays e.g. the Eagle Ford, Texas.
Recently acquired 2D seismic has identified large conventional leads at Project Icewine within the same Brookian petroleum system and shallow to the HRZ shale, including potential high porosity channel and turbiditic sands associated with slope apron and deepwater fan plays. The Brookian conventional play is proven on the North Slope; the USGS (2013) estimated the remaining oil potential to be 2.1 billion barrels within the Brookian sequence. Two recent discoveries in the Brookian have already exceeded these estimates, with Armstrong/Repsol discovering 1.4 billion barrels in 2015 and Caelus announcing a 2.5 billion barrel discovery in 2016. Additional conventional potential exists in the Brookian delta topset play, deeper Kuparuk sands and the Ivishak Formation.
A Prospective Resources Report by DeGolyer and MacNaughton, was commissioned by 88 Energy to evaluate the unconventional resource potential of Project Icewine in February 2016 and was released to the market on 6th April 2016.
About 88 Energy: 88 Energy has a 77.5% working interest and operatorship in ~271,000 acres onshore the prolific North Slope of Alaska (“Project Icewine”). Gross contiguous acreage position will expand on award of additional leases successfully bid on in the December 2016 State of Alaska North Slope Licensing Round. The North Slope is the host to the 15 billion barrel Prudhoe Bay oilfield complex, the largest conventional oil pool in North America. The Company, with its Joint Venture partner Burgundy Xploration, has identified highly prospective play types that are likely to exist on the Project Icewine acreage – two conventional and one unconventional. The large unconventional resource potential of Project Icewine was independently verified by leading international petroleum resource consultant DeGolyer and MacNaughton. In addition to the interpreted high prospectivity, the project is strategically located on a year-round operational access road and only 35 miles south of Pump Station 1 where Prudhoe Bay feeds into the Trans Alaska Pipeline System. The Company acquired 2D seismic in early 2016 to take advantage of the globally unique fiscal system in Alaska, which allowed for up to 75% of 1H2016 exploration expenditure to be rebated in cash. Results from the seismic mapping and prospectivity review are encouraging, and form the basis of a conventional prospectivity portfolio for Project Icewine. In late 2015, the Company completed its maiden well at the project, Icewine#1, to evaluate an unconventional source rock reservoir play which yielded excellent results from analysis of core obtained from the HRZ shale. The follow-up well with a multi-stage stimulation and test of the HRZ shale, Icewine#2, spud in early 2Q2017.
