Currently, this well is not completed, but is expected to be completed shortly. We are submitting this application now so we can perforate this well as soon as it is completed. Depending upon the outcome of perforating the attached perforation intervals, a perf breakdown, and possibly a sand frac job will be conducted. Therefore, the attached application includes the proposed stimulation design, as well as the proposed perforated intervals. Very truly yours, D. F. Scheve DFS/CKH/ljm Attachment cc: J.S.

Pressure test tubing and casing annulus. Pump acid breakdown treatment to open perforations. Open well to flow. Rig up fracturing service company. Pump propped fracture treatment at 20 BPM using a cross linked water system with approximately 20,000 lbs of 16-20 proppant. The interval to be stimulated is from 9082-9116'. The pump schedule is outlined as follows: A. B. C. D. E.

Dear Mr. Oostermeyer: Enclosed is the approved application for permit to drill the above referenced well. The pelnnit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, amd does not authoriz~ conducting drilling operations until all other required permitting dete~inations are made. To aid us in scheduling field work, please notify this office 24 hours prior to co~encing installation of the blowout prevention equipment so that a representative of the Commission may be present to witness testing of the equipment before the surface casing shoe is drilled. ~here a diverter system is required, please also notify this office 24 hours prior to commencing ~quipment installation so that the Co~nmission may witness testing before drilling below the shoe of the conductor pipe.

Excess non-hazardous fluids developed from well operations and as necessary to control fluid level in reserve pit will be pumped down the 9-5/8" x 13-3/8" annulus. The annulus will be left with a non-freezing fluid during any extended period. The annulus will be sealed with 300 sx of cement followed by Arctic Pack. b. Wells within 200' of the proposed well are: DS 18-13 45' DS 18-14 58' DS 18-15 163' DS 18-12 183' @ Surface to 4400' TVD / MD @ Surface to 3000'TVD /MD @ 3400' TVD/MD @ Surface to 1000'TVD /MD C, The drilling fluid program and fluid surface system will conform to the regulations set forth in 20AAC25.033. d. Maximum surface pressure is based upon BHP and a full column of gas to TD (0.10 psi / ft). e. Based upon previous logs on DS 18, no potential productive zones are anticipated above 4000' TVD. f.
