The proposed 7,707 -acre onshore unit would cover two State of Alaska leases and one Cook Inlet Region Inc. lease near the Kenai Peninsula community of Kasilof. The unit application, originally filed in August 2010, sat in limbo at the Department of Natural Resources' Division of Oil and Gas for nearly a year, while officials waited for Aurora to submit a proposed unit agreement that included both the State of Alaska and CIRI as co- royalty owners. Under Aurora's proposed two -year plan of exploration, it must re -enter the Cohoe Unit No. 1 well or perform 3 -D seismic over the area by the end of September or lose the unit. Union Oil Co. of California drilled the Cohoe Unit No. 1 in 1973. Aurora must re- enter it to at least 10,000 feet, penetrating the Sterling, Beluga and Upper Tyonek formations. By Sept. 30, 2012, Aurora must either re -enter the well or run the seismic program, • • whichever it didn't do in the first year. It must apply for a PA, or Participating Area, by the end of 2012. DNR is taking comments through July 25. Thought to contain bypass play Sun Oil Co. first leased the Cohoe -area acreage in 1967, but farmed it out to Unocal in 1972. Unocal was formerly Union Oil, and is today owned by Chevron. Unocal shot seismic over the area and drilled the Cohoe Unit No. 1 to a measured depth of 15,683 feet, but the companies ultimately terminated the leases in 1975. A group of individual investors picked up the leases in a 2003 sale and Aurora acquired the acreage in early 2004, eventually adding a neighboring CIRI lease in 2006. Because Unocal encountered gas en route to targeting a deeper oil deposit that proved unsuccessful, Aurora believes Cohoe could contain a "bypass play" worth exploring, Aurora President Scott Pfoff told Petroleum News last August. "Like so many other wells drilled in the Cook Inlet, this well was drilled deeper, looking for oil and with heavier (drilling) mud," Pfoff said. "We see evidence of bypassed gas pay, but testing was minimal and we suspect negatively impacted by mud invasion into the formation." Faced with a pending exploration of the leases last summer, Aurora filed paperwork to form the Cohoe unit and to drill a re -entry of the Cohoe Unit No.1 well, but at the time the company told Petroleum News it preferred to shoot seismic over the area first in order to determine whether the original well penetrated the top of the gas prospect. But because Aurora needed its rig for operations on the west side of the Cook Inlet, it couldn't begin drilling last fall. Should Aurora ultimately drill, it is well positioned to develop Cohoe because the leases are close to existing regional infrastructure, including the Kenai - Kachemak Pipeline.

VonderAhe Petrol eum Engineer State Alaska DATE: July 19, 1974 FILE NO: TELEPHONE NO: SUBJECT: SOCAL's Falls Creek #43-6, Ninilchik River No. l, Cohoe _ Unit #1 ~ m i i I left home at 6'15 a.m. July 17th and flew to Kenai via A.A.I. Our departure was 20 minutes late so I had barely enough time to rendezvous with Wayne Wilson of. SOCAL after picking up a Hertz rental car and driving to Soldotna. We drove to the location of SOCAL's Falls Creek #43-6 which is 1.8 miles past Clam Shell Lodge and about 1/4 mile to the east of the Sterling Highway. The location had been smoothly graded and seeded but the results were inef- fectual, with grass growing in only a few areas. Wayne said they planned to fertilize and re-seed the whole area. In fact he paced the sides to get an approximate size in acres to figure the amount of fertilizer and seed to use. The marker was standard 4" pipe with a bull plug welded on top and the re- quired information was bead-welded on the pipe and painted black so it was very legible against the orange background of the pipe. The caption bead- welded in the pipe was: "SOCAL 1973-FALLS CREEK #43-6 - SE 1/4 SEC. 6 T1N R12W, S.M." The water well was left in useable condition with a 1/4" plate welded on top. The whole area was quite level except for the area of the sump which had settled 1 1/2 to 2 feet but the sides of the depression are rounded smoothly and sloping. Not vertical. Altogether the condition of location is very satisfactory. Verbal approval of final abandonment given Wayne Wilson. (3 photograph~ attached) I then drove to Ninilchik and out to Brinkerhoff, Ninilchik #1 which is 4 1/2 miles northerly from the Ninilchik airport entrance road which in turn is about 3 miles to the east of the Sterling Highway, arriving at the site at 10:15 a.m. The location is in ver~ poor condition including the well itself. The 13 3/8" surface casing is protruding about 20" above ground with the 4" pipe marker cemented into the top of it and extending more than 5 feet above it. (see photos 4,7 & 10) The 13 3/8" rat hole casing was not cut off or removed and pro- trudes more than 3 feet above ground. (same photos) The marker has infor- mation bead-welded on the side reading downward as follows: "BRINKERHOFF CO - OP. NINILCHIK RIVER NO. 1 Sec. 21 - 1S - 13W SN. EL 275 LEASE NO ADL 41217, PERMIT NO. 73-39, SPUDED 12-31-73, P&A 2/25-74". Homer L. Burrell -2- July 19, 1974 The water well 6 5/8" casing (see photo #5) protrudes about 5 feet above ground with a 1./8 inch plate incompletely welded on top with a 2 foot piece of 2 inch pipe, open at top, welded to the plate. On the 2 inch pipe is bead-welded' "WATER WELL 140 FEET". The location is fairly clean as only a couple pieces of planking were exposed near the well and a grease bucket (to the right edge of photo #10).. The surface was apparently bladed when the ground was very wet as it is exceed- ingly rough. If any attempt was made at smoothing the surface by backblading it was ineffective; probably because of surface being too wet. In left center of photo #9 which shows area to left of the location of the car in photo #8, a vertical bank about 8 feet high shows where material has been bladed out to heap up the area in the foreground of both these pictures. Recommendation: (1) That the rat hole casing be either pulled out or cut off below ground level and filled with earth, sand or gravel. (2) That the sur- face of the area be bladed and "back bladed" while dry and smoothed out. (3) I believe enough material should be bladed from an area large enough to not noticeably change the general surface elevation, and build up the area around the marker high enough to bring the surface up to cover the surface casing by a few inches, this surface could taper outward from about ten feet from the well without it being too noticeable. (4) A thicker plate or bull plug should be welded on top at the 6 5/8" casing to seal it completely. ~.~After leav-ing the Brinkerhoff location at 11'40 a.m. and stopping at Ninil- chik for lunch I arrived at Union Oil Co~p.a~KLy.,~s Cohoe.T..U~i.t The location is in excellent condition, well smoothed and cl.ean with no indication of where the sump was located which was along right side of photo #14.

Spruce trees removed from the location were limbed and stacked beside the access road. (photo #12) I walked around the perimeter of the location area and the only debris exposed was along the south slope where the rains had caused some slumping and gullying and exposed a few short pieces of 4" plastic pipe, a piece of 2" metal pipe and a few feet of wire rope. Also a rather large bundle of sheet plastic (Visqueen) was washed down one gully and into the edge of the woods. (Photo #13) This was called to their attention this morning and they promised to remove it. Final abandonment approval given by phone.

I .MUD PROGRAM 0-1800' SURFACE }tOIE Spud w/ Ben-Ex, bentonite, and soda ash. This spud mud provides a better fluid for surface holes than bentonite-time or bentonite-cement slurries. Other advantages include quick yielding of bentonite w/ Ben-Ex to reduce mixing tim, e. A Ben-Ex spud,mud provides excellent properties to insure hole cleaning in large diai:~ter holes and less of a mechanical erosional factor due to the shear thinning c~haracteristics of the fluid. ., DIRECTIONS' For 200 barrels of spud mud with a funnel viscosity, of 45-60 Sec./Qt~ 1. Build volume with fresh w~ter. 2. Add 100 pounds of soda ash to ~emove any calcium present. 3. Add 24 bags bentonite through the hopper.. 4. Add five (2#) bags of.Ben-~Ex through the hopper. For 200 barrels of spud mud with a funFe.1' vi$cpvsity' of 60-80 Sec./Qt. 1. Build volu~ne with fresh water. 2. Add 100 pounds soda ash to remove any calcium present. 3. Add 30 bags bentonite through the hopper. 4. Add five (2#) bags Ben-Ex through the hopper. 1. To build additional volume or viscosity, add 1 bag of Ben-Ex to each 5 bags of bentonite with approxLmately 15 pmmds of soda ash. The additives may be added together through the hopper. .2. Ben-Ex ~my be applied to any system where bentonite is being used. 3. Ben-Ex will acelerate~the yield of bentonite. The normal ratio is: 1 bag of Ben-Ex (two pounds) to each 5 bags of bentonite. 4. Soda ash is recommended when caici~n is present. Use soda ash in a concentration of 1/4# to 1 1/2# per barrel. For best results, pre-treat the m~ke-up water prior ~o adding bentonite and Ben-}~ when calcium is, present. 5. l~ater will be re-used'from the s~p except following cementing or where contaminants in the sump ~ter would be detrimental to the mud system.

The proper fluid loss, yield value, and gel strengths can be adjusted with 1/8 to 1.0 #/bbl. of a polyacry!ate. 6. Oil may be added if desired. '7. To reduce the high temperature-high pressure fluid loss, asphalti~ materials may be added. 1. Run a stream of water while drilling. 2. Additional Ben-Ex should be added in~.proportion to the amount of hole being drilled. 3. The proper use of mechanical solids separators should be encouraged to keep jetting and dumping of solids to a minimum. 4. To obtain the maximum benefit from a non-dispersed weighted m~d, maintain a (D/B) drilled solids to bentonite ratio of 2 to 1 or less. 6000' to 11,000" A semi,dispersed, inhibited lignosulphona~e system will be used t° lessen water dilution and maintain, proper ~nhib~ition of l°w gravity solids. ~is control will lessen the requirements for excess additions of barite.
