Diverter, BOPE and mud fluid system schematics on file with AOGCC. Hazards Sadlerochit pressure is _+3,500 psi at 8,800' TVDss or _+7.6 ppg EMW. The target polygon maintains 150ft of standoff from the faults to the north and west, but only 75- 100ft from the small south bounding fault. Small changes in amplitude along the top and base event indicate very small faults (<10') may occur within the polygon. The well i~ expected to penetrate 1 significant fault (8725' TVDSS; 9,815' MD) prior to entering the target with approximately 20ft of missing section. Depths will most likely be modified as the target is approached (depth uncertainty is +_20ft). Operational Summary 1. Set and test BPV. Remove wellhouse and flowlines, level pad, dig out cellar. 2. Test 9-5/8" packoff to 5,000psi, and function lock down screws. 3. MIRU. Circulate well with 8.5 ppg seawater. Set test dart in BPV (TWCV). ND tree, NU BOP's and test same. Pull BPV and test dart. .

The initial prognosis of 64' of light oil column has been reduced by the structure coming in 25' high and the bottom 15' being shaled out. It has been determined that the remaining 24' of 14P, which is of poorer quality rock than 13P, is not currently commercial. It is requested that K-09A be suspended with a waiver to the surface cement plug and to the original mud weight required between the surface plug and liner lap plug. The well is being suspended in this manner to facilitate future sidetracking potential. Listed below is the procedure for the suspension of K-09A. Rig: Top of window · TD of 8-1/2" hole: Top of Sag River: Doyon9 7594'md 9936'md 9192' md PROCEDURE- Notify AOGCC of intent to suspend well and notify them of plans to tag open hole cement plug. 1.

Pump 25 bbls KCI water, 46.3 bbls (226 sx) of slurry, 9 bbls of KCI water and displace with rig pump at 10 BPM to balance point. Pull DP to top of cement plug at (9336' md) and circulate the long way to clear any cement. POH with 2 stds and circulate and condition mud while mixing Plug #2. Batch mix 41.5 bbls of slurry. This is based on 444' of hole volume + 30% excess. 8.

When I arrived the rig was ready to tag cement, they tripped in the hole open ended and started taking weight at approx..8970, the cement was still not setup at 8984 and the decision was made to allow some more time for cure. I returned to the rig four hours later and a successful tag of 20K at 8995' was made. The rig then set a EZSV bridge plug in the surface casing at 7519' (Shoe @ 7594) with a 7.3 bbl cement cap and 12.7 bbl's squeezed below. I witnessed a pressure test of the casing and plug of 3500 psi for 15 minutes with no loss of pressure. The rig will freeze protect the well, run in a joint of tubing and place a dry hole tree on the casing head. SUMMARY: I witnessed the verification of placement of the open Hole cement plug well #9 in the Prudhoe Bay field.
