88 Energy Limited Operations Update
88 Energy Limited (ASX: 88E) (“88 Energy” or the “Company”) is pleased to announce the following update for its projects located on the North Slope of Alaska.
Highlights
- Nitrogen lift commenced at Icewine#2
- Yukon Gold and Western Margin leases formally awarded
Project Icewine – Icewine#2 Production Testing
As at 0530 17th June (AK time), wellhead pressure was 370psi with a flowback rate of 166 barrels of water per day on a variable choke setting, in order to manage wellhead pressure (currently 28/64”).
A production log was run on 12th June and confirmed that all perforations were contributing to flow. As per the flowback design, nitrogen was then introduced gradually to the wellbore from 0845 13th June (AK time), prior to installation of the coiled tube velocity string, to artificially lift stimulation fluids in order to gain connectivity to the reservoir. The flowback rate stabilised at 200 barrels of water per day through an 8/64” choke and then steadily declined to circa 100 barrels of water per day, as per expectation.
Flowback was interrupted, as per the program, on the 15th June 08:00 (AK time) to allow installation of the velocity string. Flow was re-established on 15th June at 20:00 (AK time) with nitrogen introduced into the annulus between the 4.5” casing and the 1.75” velocity string. After displacement of fluid in the annulus, the flowback rate stabilised at 350bpwd through a variable choke to maintain a target wellhead pressure of 200-400psi. This technique decreases the backside pressure in the system and optimises lifting of fluid from the wellbore.
Flowback is now being run through the separator and gas chromatograph and is considered to be 100% stimulation fluid and gas. The gross gas rate is averaging 571mcf/d. Approximately 24.8%, or 142mcf/d, of this is estimated to be hydrocarbons with the remainder being returned nitrogen, injected as part of the artificial lift. Hydrocarbon content is mostly methane (90%) with some heavier elements up to trace C6. The composition and rate is as expected for this stage of the flowback and results are considered unrepresentative of the hydrocarbon composition in the reservoir, as the well is still in clean-up phase. Salinity measurements of the flowback fluid indicate that connectivity to the reservoir remains limited, as expected, at this early stage.
Total clean up fluid returned (net of diesel for freeze protection and any other fluids introduced as part of the current operation) since commencement of flowback on 12th June is 820 barrels (interpreted as 100% stimulation fluid). Total fluid returned for the entire flowback operation, including last year, is now 6,353 barrels or 23% of the frac fluid injected vs a target percentage return of at least 30%.
The Icewine#2 well is located on the North Slope of Alaska (ADL 392301). 88 Energy Ltd (via its wholly owned subsidiary, Accumulate Energy Alaska, Inc) has a 77.55% working interest in the well. The well was stimulated in two stages over a gross 128-foot vertical interval in the HRZ shale formation, from 10,957-11,085ft TVD, using a slickwater treatment comprising 27,837 barrels of fluid and 1,034,838 pounds of proppant.
Prior to Winter shut-in (2017) 20% of the stimulation fluids had been flowed back versus a projected minimum target of 30% to gain connectivity to the source rock reservoir.
Flowback commenced, on schedule, at 22:30 11th June 2018 (AK time) to clean-up stimulation fluids from the Icewine#2 borehole with a well head pressure of 3,000 psi and flowback rate of 253 barrels of water per day on an 8/64” choke.

Flowback commenced, on schedule, at 22:30 11th June (AK time) to clean-up stimulation fluids from the Icewine#2 borehole with a well head pressure of 3,000 psi and flowback rate of 253 barrels of water per day. As at 1230 12th June (AK time), wellhead pressure was 816 psi with a flowback rate of 160 barrels of water per day. Based on the pressures and flow rates, there is no indication of any impediment to flow through the perforations at this stage. A production log has been run to confirm this, and the results will be disclosed to the market once the report has been finalised.
At this early stage of flowback, the fluid has not been run through the separator, so the hydrocarbon rate has not been measured. Flowback through the separator and gas chromatograph is expected to commence today.
The velocity string, comprised of 1.75” coiled tubing, is ready to be installed and connected to nitrogen lift utilising a membrane unit, currently set-up on location.

Pressure build-up analysis indicates no deterioration in fracture half-length
Commencement of flowback at Icewine#2 on schedule for 11th June
Project Icewine – Icewine#2 Production Testing
Post the retrieval of downhole gauges in Icewine#2 on 25th May, pressure build-up data was subsequently downloaded on the 30th May and processed. This data was then analysed and interpreted to determine whether any degradation of the fracture system created by the artificial stimulation had occurred during the shut-in period.
The analysis showed that the fracture geometries of the first pressure build-up, (July-August 2017), when compared to those from the second pressure build-up over Winter, (September 2017-June 2018), are very similar, with estimated fracture half-length of 504ft and 500ft, respectively. This is encouraging and indicates that the fracture system created has not undergone degradation. Given this, and the evidence of no build-up of debris in the wellbore, no remedial action will be required prior to commencement of flowback.
Mobilisation of equipment and personnel for the re-commencement of flowback of the Icewine#2 well, utilising artificial lift, is now in full swing and operations remain on schedule for start-up on the 11th June.
