All other sundry approval stipulations apply. Winton Aubert AOGCC 793-1231 McLaughlin, Sean M wrote: Winton, When the sundry was submitted for G-10B it was thought that no cement was present is the 3-1/2" x 7" IA at 9470'. In order to mill a window cement was planned to be squeezed into the annular space and into the G-10B liner. The scope of work was as follows: Pre-IDe: Work I) Tubing has been inspected with a PDS caliper and is in good condition. 2) Integrity testing of the entire well is yet to be performed. 3) The 3 W' tubing will be punched in two places, 9493-97 and 9250-54. 4) A cast iron bridge plug will be set at 9485'. 5) A mechanical whipstock will be set at 9470'. 6) A minimum of 20 bbls of cement will be down squeezed through the punched 3 W' straddle to cement both the straddle annulus and the G-l OB liner. 7) Remove flow line, remove well house, and level pad. A Cement bond log was run and we determined there was good quality cement in the 3-1/2" x 7" IA at 9470'. Unfortunately the CIBP was set on the next run and it is not possible to squeeze cement as planned. I propose the following as revised pre rig work: Revised Pre-Rig Work Summary: I. S Set DGL V in station #2. Done 2. S Run dummy whipstock drift to 9500 ft (top of2 3/8" liner). Done 3. S Tubing has been inspected with a PDS caliper and is in good condition. Done 4. 0 MIT-IA and MIT-OA Done 5. E Cement bond log 9100' to 9500' Done 6. E A cast iron bridge plug will be set at 9485'. Done 7. E A Weatherford 3-1/2" LSXwillbe set at 9470'. 8. 0 Remove flow line, remove well house, and level pad. The top perforation in G-10 is at 9924' MD. BP has set a CIBP at 9485' and a whipstock at 9470'. The sidetrack will exit G-10B into the Ivishak (Zone 4). The primary cement job on G-10C will be brought to the top of the liner at 9425'. BP requests a waiver to 20 MC 25.112(E) which states the following: (E) if the perforations are isolated from open hole below, a mechanical bridge plug set no more than 50 feet above the top of the perforated interval, and either a minimum of 75 feet of cement placed on top of the plug by the displacement method or a minimum of 25 feet of cement placed on top of the plug with a dump bailer. lof2 5/2/2006 3 :49 PM e e MICROFILMED 07/25/06 DO NOT PLACE ANY NEW MATERIAL UNDER THIS PAGE F:\LaserFicbe\CvrPgs _ Inserts\MÏcrofilm _ Marker.doc ) ) FRANK H.

G-I0B is a Zone IB sidetrack drilled in 2002. Initial rates were low and continued to decline despite several add perf jobs. Over the past 12 months G-10B has /' been produced only 5% of the time due to high GOR. With no further well work options available, a sidetrack to a new area is planned. /" The sidetrack, G-I0C, is scheduled to be drilled by Nordic 1 on or about Feb. 12.2006. The plan calls for cement squeezing both the G-10B liner and the 3 Y2" x 7" straddle annulus to prepare for a two-string window in Zone 2. The following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed sidetrack is attached for reference. ~ . Pre-Rh!: Work 1) Tubing has been inspected with a PDS calliper and is in good condition. 2) Integrity testing of the entire well is yet to be per:~~' --/J 3) The 3 ~"tubing will be punched in two places, 9:t1?'':J7 and 9t~. 4) A cast iron bridge plug will be set at 9485'. - -- 5) A mechanica:æw ipstock will be set at 9470' . 6) A minimum 20 961s of cement will be down squeezed through the punched 3 Y2" straddle to cement both the strae1lnnulus and the G-10B liner. 7) Remove flow line, remove well house, and level pad. The pre CTD work is slated to begin about Jan. 27. 2006. , . \~~ \ 0 - 4-0 ~ CA.f r YO tJ c....{ · Rie: Work 1) MIRV Nordic 1 and test BOPE. 2) Mill 2.74" window in Zone 2 through the 3 ~" x 7" straddle. 3) Drill sidetrack into Zone 1 B target. 4) Run solid 2 3/8" liner and cement. 5) Cleanout liner and perforate for production (-800 ft of perfs). 6) Freeze protect well and RDMO. Post- Rie: Work 1) Install well house, flow line and gas lift valves. ~~- CTD Drilling Engineer 564-4694 CC: Well File Sondra Stewmanfferrie Hubble ) TREE = 3-1/8" FMC W 14" QU WELLHEAD = McEVOY ACTUATOR = AXELSON "kB.I~[èT;'- "-'^--'""-~^--~"^7Õ'j' Bï=:..E[E\,r;·····^····^..···.._..·__.._m^'^'"_m32~27ï ~,.'^....~~"......"',.,,~..,,,.. ."'''".'''.,.w,..,,·,.''.,''......n..''n'''~'........,.,,.,................''.fi,...,.'

(2) All depths are Bit Depths unless otherwise noted. (3) Logging data from 9593' MD (8689' SSTVD) to 10917' MD (8957' SSTVD) was provided by Sperry Sun Drilling Services. The data from 10917 to TD is memory data. (4) Well G-10B is a sidetrack of the original well G-10, kicked off at 9620' MD (8706' SSTVD). (5) Baker Hughes INTEQ run 1 utilized TINY TRAK with Gamma services from 10917' MD (8957' SSTVD) to 11241' MD (8951' SSTVD). (6) The data presented here is final and has been depth shifted to a PDC (Primary Depth Control) curve supplied by BP (SWS, 29-06-2002). (7) The depth from 11241' MD (8951' SSTVD) to 11223' MD (8951' SSTVD) was not logged due to sensor to bit offset.
