Charlie Bravo Conventional Drills

Stephen Staley:
Is this working? Can you hear me? It is working. Very good. I'm just going to go back a few slides, folks, to that one. I'm going to talk about the conventional. I'm the one who's got a tie on, so that's what you'd expect, I suppose. We're down here. Obviously, we've seen this slide before. Dave mentioned the green blobs here. Now, back in 2013, the US Geological Survey estimated that there was about 2.1 billion barrels to come out of what's called Brookian or the Brookian system, which is the conventional here. It extends into our acreage. Since then in those very few years with these three discoveries. Caelus there in the northwest, Armstrong and Repsol here, and ConocoPhillips earlier this year, they've already almost doubled that estimate. There's an awful lot of potential here. They haven't, by any means, found everything there is to find.

Way down here, the system extends down here. Tarm/Meltwater here. It's an existing field. That's one of our analogs for what we've got out here and across our acreage in terms of potential conventional play. Very exciting on the conventional side as well. I'll take it forward to where we were before. This now is a map of the acreage. The green blobs are, and you've probably seen these, they've been released. These are the conventional leads that we found. We can't call them prospects yet. We have more work to do on them before we can call them prospects. Very exciting.

You saw Alpha. If you came to the last one of these, we show you a little graphic of Alpha. We've moved further west. This is based on the 2D seismic that we acquired early last year, and processed and interpreted and we continued to work on. As you can probably see from this, we've got stacked plays. Here, we've got India/Juliet, et cetera. Over in the west, picked out just Bravo. We've also got Charlie. Charlie and Bravo overlap. Each of those is quite significant. We got well control over in the west here with Malbec, Smilodon, and Wolfbutton wells.

What do we think we've got? In broad terms, we've done an initial pass on this. Net to us, net to 88, probably about 1.14 billion, about one-and-a-half altogether billion barrels. Very significant. It's not quite as big as the unconventional, but by anybody's terms, that's a very large number to have sitting in your acreage. Now, this requires more work. We need to build in to our analysis, the data from the wells that we've got already over in the west there. We'll be working up what's the right way to approach this, where do we want to drill this.

If we have a look at this list here, then from east to west and we group them, you can see the size of what we've got. Alpha, we estimate in total about 118 million barrels. Then, through the center, so pretty big ones as well. There's Golf and India. As we get to the west, if you look at Bravo and Charlie, the size of those both net to 88 Energy, over 200 million barrels each. There's a potential there to drill both with one well. Also in the west, one can keep going deeper with a single well and also get down to the HRZ. You got a lot of potential for getting a lot value out of a single well. We can start to do more things with the data. We can pull out seismic attributes and start to work on that, especially in the east where we've got access already to some of the 3D data. I think in summary, I'd say very exciting and watch the space. Dave?

Iceroad Construction
This high pressure spray pump is used for building ice pads faster than ever before. The way this unit works is it pumps a large amount of water at high pressure into the air about 100 feet up, then as it falls back towards the ice it goes through rapid cooling from the ambient air being -30 to -40

Iceroad Permit Application Oct, 2017

Accumulate Energy Alaska Inc., the local operating company for Australia-based 88 Energy, has begun permitting for two winter exploration wells - Bravo 1 and Charlie 1. The company has drilled two Icewine wells from the Franklin Bluffs gravel pad south of Deadhorse and adjacent to the Dalton Highway, and is testing Icewine 2. Because the existing gravel pad is accessible year-round, that work did not require ice roads or ice pads.

The new wells will be 22 to 25 miles west of the Franklin Bluff gravel pad, Accumulate said in an application to the Alaska Department of Environmental Conservation for an update its oil discharge prevention and contingency plan.

Bravo 1 and Charlie 1, planned for winter 2018, will be drilled from ice pads accessed via a tundra winter ice road, and will be drilled “to further evaluate the opportunity to explore for additional oil deposits within the Accumulate lease block,” the company said.

Plans for 2018 drilling
Accumulate said in its project overview that Bravo 1 and Charlie 1 are targeting conventional oil deposits in the company’s western play fairway some 39 miles south of existing North Slope development.
The company said it will construct and operate infrastructure to drill the two exploration wells, including construction, operation and maintenance of ice roads and pads.

Field studies are planned for late June through mid-September, with installation of thermistors from July 1 through mid- September. Staking and pre-packing of ice roads and pads will begin in mid- November and run through the first of the year; construction of ice roads and pads will begin in mid-December and run through Jan. 21.

Mobilizing the drill rig, camp and support operations will begin Jan. 21 and run through the end of January.

Drilling and testing the Bravo 1 well is planned for Feb. 1 through April 14; drilling and testing the Charlie 1 well is scheduled for March 1 through April 14, with demobilizing the drill rig, test, camp and support operations scheduled for April 14 through April 24, with summer stick picking and tundra remediation from July 1 through Sept. 15.

Construction
The tundra winter ice road will be constructed starting from mile post 386.5 of the Dalton Highway to the proposed Bravo ice pad and then an access road will be constructed from the Bravo pad to the proposed Charlie pad.
Accumulate said the proposed wells are some 22 to 25 miles west of the Franklin Bluffs pad. A map included in the DEC application shows the ice road running southwest from the Dalton Highway to the Bravo pad and then northwest to the Charlie pad.

The cross country ice road is estimated at 23.2 miles, with 14 lakes and two gravel pits to be accessed for water and ice chips. The 500-by-500 foot Bravo had will be at the southern terminus of the ice road; a 4.7-mile long access ice road will extend west then north from the Bravo pad to the Charlie pad, which will also be a 500-by-500-foot pad.

Accumulate said the ice roads will be built to accommodate drill rig moves, with pre-packing requested prior to official tundra opening to drive frost down and preserve early snow.

The company also said that where ice roads cross established subsistence trails they will be constructed to provide a smooth transition to ensure subsistence trail users have safe passage.

Drilling
Accumulate said both wells will be drilled to a depth of some 11,000 feet to test conventional objectives within the Seabee formation.
A mobile land drilling rig similar to the Arctic Fox will be used, with the same rig drilling both wells.

The plan is to test and hydraulically fracture both wells, and Accumulate said the wells may include laterals, sidetracks or additional penetrations from the same exploration pad. Each well involves a vertical hole to about 10,000 feet, with measure while drilling, log while drilling and wireline conducted in the open hold, along with rotary sidewall coring and repeat formation tester fluid sampling, the company said.

Phase II of the programs would include hydraulic stimulation and flow-back testing of prospective intervals to evaluate reservoir production.

The Bravo wells will be a tract operation in Alaska Division of Lands leases 393048, 393049, 393058 and 393059. The Charlie well will be in ADL leases 393043, 393044, 393052 and 393054.

All of the tracts are owned 77.5 percent by Accumulate and 22.5 percent by Burgundy Xploration, per a November 2014 agreement between the companies whereby 88 Energy acquired an 87.5 percent working interest, reduced to 77.5 percent on spud of the first well. Kristen Nelson Petroleum News
