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
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

Project Icewine Overview
In
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 (
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.
Exploration incentives provided by the State of Alaska with up to 35% of net operating loss refundable in cash were concluded for all expenditure post
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
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
