DS 7-4 Recommended Abandonment Procedure The recent finding by Wireline Ops. that the 3-1/2" tubing in well DS 7-4 is collapsed and/or buckled at 8353' md precludes the use of coiled tubing to abandon/prep the well prior to redrill operations. Doyon 16 will now be charged with performing the necessary remedial tasks to effect the abandonment of the existing DS 7-4 wellbore. The scope of the rig work will include the following: 1. Notify an AOGCC representative prior to commencing operations. 2. MIRU Doyon # 16 - circulate/kill well w/8.5 filtered seawater 3. Pull BPV & install two way check valve. ND tree 4. NU 13-5/8" BOP's. Test BOP's to 5000 psi. Pull two way check valve. 5. Pull and lay down 5-1/2" x 3-1/2" tubing. 5.a. In the event that the 5-1/2" x 3-1/2" tubing can not be pulled - RIH w/E-line and jet cut tubing @ +/- 8353' md. Pull 5-1/2" x 3-1/2" tubing. 5.b.

Loaded wellbore w/506 bbls Seawater containing 1% Chevron Chaser Surfactant, then pumped Nitrogen, to treat the open perforations at: 9248 - 9279' MD (Z2) 9298 - 9318' MD (Z2) Ref. Log: BHCS 9/10/78. Note: the open perforation interval at 9200 - 9231' MD, is straddled & isolated, and was not treated. Pumped Nitrogen at 1200 scf/min (initial) and increased rate to 3100 scf/min (final). Pumped a total of 200 Mscf Nitrogen, then switched back to pumping 504 bbls Seawater w/ 1% Surfactant, @ 3 bpm, followed by another 200 Mscf of Nitrogen at 1250 - 3700 scf/min. Shutdown Nitrogen. Rigged down. 9/21/91: MIRU & RIH to set a 1.25" ID tubing patch from 8764.3' to 8791.0' MD (seal to seal) over a 3-1/2" tubing leak located at 8786' MD. POOH. Rigged down.

I caught a ride with Arco security. to Drill Site #7 where I met Georg~ Bean, drill/rig f~, and Jim ~atherly, Rowan rig ~34 toolpusher. Nippling up was in progress. Tem~ra~are +45° F, clear skies, no w~nd. ~=dnesday, A._ugust 30, 1978 - Testing was delayed in order to change organized, rig ~.n good repair, reserve pit w~ll built, and the well sign was in plaoe. Dart and ball type floor valves w~re in place. Testing began at 3:15 PM with shoe on 13 3/8" set at 2724'. Annular pre~_nter teste~ to 3000 psig. Upper pipe rams, wing and HCR valve in the choke 1/ne and both ,~ing val~es .and check valve in the kill 1/ne tested to 5000 psig. Eleven valves and tw~n~-s~ flanges in the choke manifold tested, to 5000 psig. Th~ Swaco supe_ ~e was actuated both fully open and fully closed and the manual adjusta_~01e choke was free m0ving. Acc~tor pressure was 2900 psis. N~_ backn~) bottles tested to 2350, 2300, 1700 and 2600 psig. $~ith ~he acomulator pump off all three ram type preventers and annular preventer were closed simul~ly. Accumulator pressure dropped to 900 psig and remained steady. The acomTulator pump was then turned on and acomu]ator pressure climbed back to 2900 psig in 4 ½ n~_nutes. Blind rams and lower pipe rams then tested to 5000 psig. Finally kelly cock and lower kelly valve tested to 5000 psig and tests w~re concluded at 5:25 t~4. A field ir~"tion report was prepared with a copy given to George Bean, a copy ~.~iled to Bob Hines, and the original atta~ to tb~s report.

A string of 5-1/2" 17# N-80 tubing, packer, and necessary provisions for subsurface safety equipment will be run. The packer will be set above the Sadlerochit. A non-freezing liquid will be left in all uncemented annuli within the permafrost interval. Selected intervals within the Sadlerochit interval will be perforated,. and reported on subsequent report. A 5000 psi WP wireline lubricator, tested to working pressure, will be utilized with all wireline work. Well will be flowed to production facilities during perforating and testing.
