INSTRUCTIONS GENERAL: This form is designed for submitting a complete and correct well completion report and log on all types of lands and leases in Alaska. ITEM 1: Classification of Service Wells: Gas injection, water injection, steam injection, air injection, salt water disposal, water supply for injection, observation, injection for in-situ combustion. ITEM 5: Indicate which elevation is used as reference (where not otherwise shown) for depth measurements given in other spaces on this form and in any attachments. ITEM 16 AND 24: If this well is completed for separate production from more than one interval (multiple completion), so state in item 16, and in item 24 show the producing intervals for only the interval reported in item 27. Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval. ITEM 21: Indicate whether from ground level (GL) or other elevation (DF, KB, etc.). ITEM 23: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. ITEM 27: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut-In, Other-explain. ITEM 28: If no cores taken, indicate 'none'.

To: State of Alaska Date: June 11, 1997 From: Greg West Doyon 16 Operations Drilling Engineer Subject: C-20A P&A Operations Summary: Pre-Rig Operations: Note: original KBE was 67.20', BF elevation is 34.30' 1. Notify AOGCC prior to commencing P&A Operations. Note: Due to the poor condition of the 5-1/2" tubing, the final P&A of perforations will occur later with the drilling rig (Doyon 16). 2. Make a chemical cut with a 4-7/16" chemical cutter in the 5-1/2", 17.0#, L-80, BTRS AB/MOD tubing at 9100'MD. Please note that there is a coil tubing patch restriction in the well bore which was last tagged at 9140' MD. 3. Circulate and kill the well with sea water. 4. Freeze protect well with diesel to 2000' MD. 5. Test pack off and service lock down studs. Report results to rig supervisor as soon as possi- ble. Lock open or pull SSSV (SSSV is DBD wireline retrievable). 6. Install a BPV and test same. 7. Remove the electrical lines, well house and flow lines. Prepare for rig arrival by leveling pad and digging out cellar. Rig 8. 9. 10. 11. 12. Work Summary: MIRU, verify pack off has been tested or retest. Pull BPV. Circulate the well to remove freeze protection and any trapped gas. Set and test TWC to 1000 psi. ND tree, NU and test BOPE. Circulate Seawater. Pull and LD 5-1/2", 17# tubing to pre-rig cut depth (-.,9100' MD). (The tubing is cut here due to the KOP being planned at 9000' MD and a tubing restriction ..-9140' MD) Ensure that the bottom hole can take fluid (inject through remaining tubing). Note: PE's were able to pump down the tubing and establish an injection rate of 4.7 bpm at 1550 psi on June 9, 1997. Run and set a 9-5/8" EZSV on Baker 20 setting tool (w/CCL). Once the EZSV is set perform a casing integrity test to 3500 psi for 30 minutes. PU EZSV stinger (plug catcher just above EZSV stinger) on 5" DP. RIH to EZSV and sting in. Establish injection rate into perforations from 12414-12458' MD. Mix and pump 76 bbls - 372 sacks - of class "G" cement (calculated as 7", 26# casing capacity from PBTD to TOL + 150' of 9-5/8, 47# casing capacity + 15 bbl to squeeze into perfs), displace with seawater to place cement from 11555' MD to PBTD at 12521' MD.

The reasonable drilling envelope of your proposed direction drilling plan for C-20 encompasses portions the wellbores o.f C-12, C--13 and C-14o To mitigate the possibili.ty of a catas- trophic event, our approval f'o~ the drilling of C-20 as-Planned is subject to the requirement that producing wells C-12, C-13 and C-14 be: (1) shut-tn~ (2) the SSSV($) closed and (3) any annular pressu~,e between 'tubing and 9 5/8" casing and between 9 5/8" x 13 3/8# casing strings be bled off while drillin~ C-20 fr~ a measured depth of 1500' to ~100'. In the event that tubing x 9 5/8* annul i cannot be bled off and sustained, ~e will consider approvin~ the drilling of C-20 below a measured depth of 1500' only after installation of a diverter system. Well samples and a mud Io~ are not required. A continuous directional survey is required as per 20 AAC ~5.050(b)($). If available, a tape containing the digitized log info~atton shall be su~Itted on all logs for copying except e~eri~ntal logs, velocity su~eys and dieter surveys. ~any rivers in Alaska and their drainaze systems have been classified as important fox, the spawnin~ or migration of anadromous fish. Operations in these areas are subject to AS 16.05.870 and the regulations pr'oc~mlgated thereunder (Title 5,.Alaska Administrative Code).

Prior to commencing operations you may be contacted by a representative of the Department of Environmental Conservation. To aid us in scheduling field work, we would appreciate your notifying this office when the well is to spud. We would also like to be notified so that a representative of the Commission may be present to witness testing of blowout preventer equipment before surface casing shoe is drilled.
