Ensure that it is shut-in during MIRU and during RDMO operations with as little shut-in time as possible, as it is a high priority producer. Please provide total well preparation cost on the handover form. Rig Sidetrack Procedure (P&A Outline Onlv) 1. MIRU. NO tree, NU and test BOPE. Circulate well clean. 2. Pull the 4 %" tubing completion. 3. PU DP and set Baker Window Master Mill Assembly at 9100MD on top of the tubing stub. 4. Sidetrack through TSAG at 821 O'TVDss (window @ 9100' MD). Geosteer as necessary to the top of Zone 1 @ 10,008' MD (8653 TVDss), building angle to 71.5 degrees and continually turning left in and through the left trending polygon. 5. Drill out with MWD Dir I GR from 9100-9600 (mid Zone 2). Trip for BHA #2 with full suite of MWDIlWD logs (Dir/GR/ReslNeu/GR). Continue drilling with this logging BHA to the end of the polygon. Polygon is from 10,440 - 13,171 MD. If possible, rotary drill from 9900 to 10,050 MD to confirm GOC wlNeu Den tool. Doglegs will need to be less than 15 Oeg/100'. 6. Drill to TD with geosteering for GOC and KaVik placement. Watch for faults. TO @ 13,171MD. Condition hole, spot liner pill, and RIHw/4.5" liner. 7. Run and cement 4.5" liner from planned top 8950'MD to 13,170' MD. 8. Perforate selected zones. 9. Run 4 1h" tubing completion with WOA tailpipe & WLEG stung into top of liner. 10. NO BOPE, NU and test tree. RDMO. ¿;:;;;---~, .~ Dan Stone Drlg Eng.

The rig was clean and all equipment seemed to be in good working order. The location was clean, but there was limited access to the rig due to the location of the well which was on the connor of the pad. Summary: I witnessed the weekly BOPE test on Doyon rig 9 drilling BPX's K-20 - test time 2.5 - 0 failures.

Since permitting the well, two changes in the original plan have taken place. · In the intermediate hole section, there may be the presence of a thin bedded, low permeability oil zone -- the Sierra Nevada, also called the Kingak -- at 7980' TVDss, 87921 MD. If the presence of this zone is confirmed by logs, the casing will be cemented to 77921 MD. This job will require 615 sacks (126 bbls) of 15.8 ppg Premium cement. · Depending on the quality and quantity of reservoir sand, K-20 may be extended beyond the planned 112491 TD. In this case, the horizontal section would be extended by about 3501 MD, giving a total well depth of 115991 MD, 8797 TVD, and total horizontal section of 13581.

The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test. Notice may be given by contacting the Commission petroleum field inspector on the N lope pager at 659-3607. BY ORDER OF dlf/Enclosures cc: Department of Fish & Game, Habitat section wlo encl.
