That approval number is~02-219~ The plan that was approved included the setting of an IBP above open Zone 4 perfs prior to downsqueezing cement past the whipstock. I am requesting that this procedure ~e modified as follows: 1. The IBP will not be used. / 2. The whipstock will be set at 10,100', in existing Sag R. perfs, as originally planned. ~ 3. A minimum of 20 bbls of 13.8 ppg cement will be downsqueezed past the whipstock in order to cement off the open Zone 4 perfs as well as the open Sag R. perfs. A pressure test of 1000 psi will be achieved.~'The cement job will be repeated if needed to achieve the pressure test. This change is proposed in order to more securely isolate the existing Zone 4 perfs from the Sag R. sidetrack to b~ drilled. The primary completion planned for the Sag R. sidetrack is an uncem~nted slotted liner. The change in the prep procedure will better insure that the existing Zone 4 perfs are isolated from the Sag R. sidetrack. / Please call to discuss if there are any questions.

The sidetrack, R-31a, will kick off from a window milled in the Sag River formation and will target the Sag River. The following describes work planned to prep for sidetracking and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed sidetrack is attached for reference. 1. The wellhead and outer annulus have been successfully tested. 2. A tubing calliper will be run to confirm tubing condition. 3. All GLM's will be dummied off and an MIT-IA performed./. 4. An inflatable bridge plug will be set at approx. 10,240' to'isolate existing Zone 4 perfs. 5. A mechanical flow through whipstock will be set at approx. 10~00', in the Sag R. interval. 6. Service coil will downsqueeze a minimum of 20 bbls cement-past the whipstock to squeeze off existing Sag R. perfs and to add cement above the IBP. 7. Drilling coil will do the window milling. Steps 2-6 will be performed between August 15 and Sept. 10, 2002. Drilling coil is scheduled to mill the window and drill the sidetrack on Sept. 20, 2002.

Jul¥...ll, 1992 I witnessed the initial BOP test on Nabor's Rig 28-E drilling BP Exploration's Well #R-31. The test went well with all equipment passing except the upper pipe rams, which would not seal. These were cycled twice with the same results and we continued on with the test. The accumulator had a recharge time of :25/1:25, which is fast even for a Ross Hill. The rig will repair the pipe rams before drilling out of the shoe. In summary, I witnessed a good BOP test on Nabor's Rig 28-E, which produced one failure, the upper pipe rams which~will be repaired before drilling out of the shoe. *Note: At 2000 hours, Laverne Linder called to advise me that the pipe rams had been replaced and tested to 5000 psi. I passed the rig to start drilling.

After discussing some future changes to the layout of the rig's substructure, the diverter was function tested. I found the diverter system to be well laid. out and functioning properly. Closure time of the annular preventer was twenty eight seconds, which is one of the faster times I have encountered. As I have noticed before, it is becoming incre as ingly difficult to lay out the vent lines where they are not &oointing at adjacent well flowlines. This is a problem that ~-~/will not go away and will only worsen with time. I should add ':~ ~\'"~'"/me is possibly incorporating a central vent l°ine into the layout of future pad construction possibly using heavy wall 13 3/8 casing which terminates at either end of the pad in a safe location. In summ~r¥, i witnessed the diverter function test on Nabor's Rig 28-E, BPX Well R-31.

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 North Slope pager at 659-3607. Sincerely, David W Jot~O-~.

RECEIVED LDT/GR, RFT J U N 0 !992 Alaska 0ii & Gas Cons. 6ommissiOn Anchorage Drillinq Problems: Refer to R-1 mud Icg for formations data about R-Pad. There is a thick coal layer at 3900' to 4100' TVDBKB which should be drilled with caution. Well R-21 experienced excessive torque (suspected from the coal) which led to stuck pipe. Drilling the production hole with the Sag River possibly highly underpressured could lead to differential sticking. Care should be taken to maintain pipe moving, proper collarS stabilization, and keeping mud weight under control. Annular Injection' Wells with open annulus will be researched. Call WOA PE for testing nearby well to cheer on open annulus. Freeze Protection: 4-1/2" tubing and its annulus will be freeze protected by evacuating the fluids via gas lifting thru the GLM at 3000' TVD. Dry crude need to injected down the 10-3/4" - 7- 5/8" casings' annulus for freeze protection. RECEIVED JUN 3 0 1992 Alaska Oil & Gas Cons.

The Drilling fluid program will consist of an 8.5 - 9.5 ppg spud mud in the 13- 1/2" hole, a 9.0 - 9.7 ppg water base mud in the 9-7/8" hole and an 8.6 ppg water based mud in the 6-3/4" hole. Drill 13-1/2" hole to 3050' MDBKB. Run and cement 10-3/4", 45.5#, L-80 Buttress casing to surface. Install blowout prevention eqUipment consisting of 5000 psi W.P. pipe rams, blind rams, and annular preventer. Maximum possible bottomhole pressure is 4390 psi at 8800' TVDss based on original reservoir pressure. Maximum possible .surface pressure is 3330 psi based on a gas column to surface from 8600' TVDss'and an oil column to 8800' TVDss. A formation leak-off teSt will be performed 10' below the 10-3/4" shoe. Directionally drill 9-7/8" hole to the 7-5/8" casing point above the top of Sag River Sandstone. Run a 7-5/8", 29.7 Cf NSCC casing string to within 10' of 9- 7/8" TD and cement with Class G cement around the 7-5/8" shoe. The annulus will be freeze protected by dead crude oil. Directionally drill the 6-3/4" hole to TD. Run 5-1/2" liner from TD to 250' inside 7-5/8" casing shoe and cement using Class G cement. Clean out to 5-1/2" float equipment. Change over to NaCI completion fluid. Test casing and lap to 3500 psi. Run 7-5/8" production packer on tubing. Set packer 50' above top of liner. A subsurface safety valve with dual control lines will be placed 100' below base of permafrost. Install and test Xmas tree. Freeze protect the tubing and annulus with Diesel from surface to 2300' TVDBKB. Set and test packer. The well will be perforated after the rig has been released.
