Well History Z-28 is currently injecting 6000 BWPD at 1400 psi and has seen up to 9000 BWPD at 1600 psi. The target rate for this well is 12,000 BWPD to replace voidage and maintain pressure as a result of gas cap gas production. Performance of offset injectors indicate target injection is achievable. Low injectivity is thought to be due to damage. A previous Schmoo-B-Gone treatment resulted in little increase in injectivity. A mud acid treatment is desired to improve injectivity in this well. Well was drifted 9/17/09 to 9815' ELM during an (PROF. Bottom perfs are at 9838' MD shot 8/5/09. There is a cement cap in the well 9856' ELM. 7...-2$ Bullhead ~1ud <Acid Sti7nulatian Page 1 Ot'j No portion of the below should be performed w/out first~ing time to ensure No Accidents, arm to People, and No damage t e Environment Fullbore -Bullhead Mud Acid Stimulation Open Perforations -Cement top at 9856' Zone MDT MDB H Status Z4Bu 9,663 9,693 30 O en Z4Bu/Z4B1 9,716 9,741 25 O en Z4B1/Z4A 9,753 9,803 50 O en Z4A 9,823 9,838 15 O en Design Details Total Footage 115' (lower perfs isolated with carbolite + cement to Wellbore Volume 95.3 bbl (to top of perfs) Acid Design Pickle - 53 bbls 10% HCI Pre-Flush - 110 bbls 6:1 Mud Acid - 110 bbls Pre-Acid Stimulation Pre-job planning is essential to the successful delivery of this procedure due to the simultaneous operations and logistical issues associated with working at WRD.

Bullhead Mud Acid Treatment • Filter all fluids that will enter the perforations to 3 microns absolute. • Do Not exceed maximum pump pressure of 1600 psi to prevent fracturing formation. Stay below 0.65 psi/ ft frac gradient while pumping acid treatment if possible. • Monitor IA and OA pressures every 30 minutes during treatment and note on WSR. • Acid strength to be verified and documented via titration before leaving Schlumberger. Please note the acid titrations on the WSR and have results available on location • Record time, rate, well head pressure, treating pressure, and annulus pressures in the WSR throughout the job. Note when acid and diverter stages hit the perfs and the response. • Pump acid within 24 hours of mixing to ensure mixture homogeneity. Remix acid if sitting longer than 24 hours. • Send an electronic copy of the treatment report including digital, ASCII or an EXCEL copy of pumping rates and pressures to Dan.Robertson(a~bp.com and Jack.Lau(a~bp.com. 4. Hold PJSM. • Ensure that current MSDS sheets are onsite and that safe handling procedures are followed. 5. Preheat filtered NH4C1 to 90°F.

The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10-404, Report of Sundry Operations.

The injection profile run 9/3/07 indicated 49' of fill to 9807' MD. The fill has steadily been increasing since a 2002 cement squeeze of the lower perforation intervals. TOC was noted at 9856' BKB on 6/20/02. A tag on 7/2/02 indicated fill to 9847' and on 3/5/04 fill had reached 9819' SLM. It is desired to shoot perforations in this well to increase injection into the 42P. This will support free gas voidage resulting from production in this zone by wells Z-21 a and Z-24. By cleaning out the liner in this well, injectivity should improve and the desired perforation depths can be reached. This should increase rate and recovery in these offset producers. Please contact Carolyn Kirchner at 564-4190(w) or 980-2926(c) with any questions or comments. cc: w/a: Well File 1 • • Risks & Discussion • A sundry will be required for the stimulation and perforation of this injector. • The Fluff and Stuff inethod is planned for this operation. The fill will be jetted with SBG and with HCL and overdisplaced into the perforations. The ideal cleanout depth would be 9856' (TOC) however in the event problems are encountered, the minimum requirement is to ensure access to the desired perforation depth of 9823'-9838' is 9845' MD. The total volume of fill to be fluffed and stuffed away is ~ 1.9 bbls if the ideal depth of 9850' is reached. At the minimum depth of 9845', fill volume is ~ 1.5 bbls. The IA has 217 bbls (~3500' of fluid) of 50/50 MeOH after a 4/20/02 IA FL of 3380' FL; therefore the fluid level should essentially be at surface. Subsequent IA FL shots have all shown FL to be near surface. Coil can liquid pack the IA upon arrival if needed. If the pre job IA fluid level is found to be shallower than 4000' TVDss there is no need for further liquid packing of the IA. • SBG is a basic solution and when mixed with HCL, could create a hazardous condition. Avoid commingling of these fluids on surface and use large 1% KCL spacers when changing from one to the other during the course of the job.

RU SL. 2. Drift and Tag, TEL, 2.5" sample bailer, run smaller OD toolstrings as needed. The last slickline drift & tag (9/3/07) tagged TD at 9807' resulting in ~ 49' of fill over the TOC at 9856'. Attempt to get a sample of fill for analysis. 3. Recover material in sample bailer for analysis. Mark and label sample with well #, date collected, collection depth. Include Carolyn Kirchner as contact with contact details from this program. Drop off sample at SLB lab in Deadhorse for solubility testing to determine if any other fluids will be necessary during this job. Have sample tested for solubility in SBG and acid system to be pumped. At this same time, confirm the test results of SBG and the HCL system for any precipitation issues in the unlikely event downhole interaction occurs. Contact program author with lab results. ~ • 4. Shoot IA fluid level. NOTE: The IA will be liquid packed with diesel by coil in the event high WHP's are required during the fluff & stuff operation. This will reduce differential on the packer. It is thought to be unlikely that any addtional IA liquid packing will be required. 5. Program will require a total of 50 bbls of 7.5% HCL with 20% xylene. Make arrangements with SLB for acid and associated additives for this stimulation. The acid system is included with this program package. Note acid titration results in WSR at time of pumping. CTU - SBG/F~UFF & STUFF FCO/HCL PERF WASH & STIM ° 6. MIRU CTU and flow back tanks. Rig up a jumper line to a nearby well for flowback. Notify Pad Operator that this well will need to be shut-in during the job. Rig up IA tie in. NOTE: Contact the facility ahead of the job to ensure SBG can be taken to the plant as a contingency if injectivity is lost. It is not planned to take any returns down a flowline. This is only for use in the event the well plugs off completely during the cleanout and it is necessary to displace the HCL from the ct. 7. MU BHA #1 - CR CTC, DCV, Stingers x 2, 2.25" OD Jet Swirl Nozzle. (Minimum well ID is 2.750" @ 2109') PT as per normal procedures. 8. Contact Pad Operator to shut-in injection. Freeze protect injection line as necessary. Liquid pack the IA with diesel if needed. CAUTION: Ensure all annular spaces are being monitored. Check gauges to ensure they are functioning correctly and be prepared to bleed IA and OA as necessary. 9. Open well and line up down the production tubing with 1% KCL. Perform an injectivity test at 1.0, 2.0, 3.0, and 4.0 BPM. Make last rate at maximum pump rate. Do not exceed 1500 psi WHP. Note results in WSR. 10.With the well shut-in, pump 10 bbls of SBG into the production tubing followed by ~ 2bbls of 1% KCL as a spacer. 11. As the coil will be full with 60/40 methanol, line up down the coil with 1% KCL, pump 2 bbls of 1% KCL as a spacer and then pump SBG. Jet from surface to 2000' with 60/40 methanol water at maximum rate while displacing the coil. Once SBG is at the nozzle, jet tubing at ~ 1.5 BPM and 60-70 ft/min. This will leave SBG in the tubing and the well freeze protected during the jetting and fluff and stuff operation. 12.Continue jetting with SBG down past the tubing tail to ~ 9300'. SD and RIH to dry tag top of fill. Correct CT depth to corrected ELMD obtained from recent S/L tag to place nozzle depth on ELMD for the cleanout. This tie-in is important to ensure the desired cleanout depth is achieved. Note depths and corrections in WSR and then PUH 10' flag coil, and PUH to ~ 9300' while keeping the well liquid packed. NOTE: To avoid swabbing the well or bringing any solids in, keep the well liquid packed and replace voidage when ever coil is being pulted from the well. ~ • 13.Once back to 9300', come back on line with SBG at ~ 2.5 BPM and continue jetting down to the top of fill. Once at the top of fill, continue jetting with SBG as necessary while fluffing and stuffing into the formation. Take small bites and chase up to above the perfs to ensure all debris has been pushed into the formation. Use SBG while jetting and 1% XS KCL while chasing up through the perfs. If well appears to be locking up with debris, then it may be necessary to continue the cleanout the long way taking returns up the backside. Maximum WHP for fluff and stuff operations should not exceed 3000 psi. Attempt to cleanout to 9850' ELMD. If problems are encountered cleanout to at least the minimum depth of 9845' ELMD. NOTE: During the fluff and stuff, SBG will be soaking in the tubing to clean any remaining schmoo from the tubing. This will be displaced into the formation once the liner has been cleaned out. 14. If a hard crust is encountered that can not be jetted through with SBG or 1% KCL, perform the following steps: a. PUH to 9300' while pumping 35 bbls of 1% KCL down the tubing, then pump 10 bbls of 7.5% HCL, follow acid with at least 35 bbls of 1% XS KCL. These 1% KCL spacers will keep the HCL from being neutralized by the SBG. b. Once 1% KCL is at the nozzle, RIH displacing all SBG from the liner down to the crust and into the perfs before the HCL gets to the nozzle. 1% KCL ahead and behind is to keep acid away from the SBG in the coil and downhole. Use ~10 bbls of the 50 bbls of 7.5% HCL w/xylene on location to jet with. Let soak and resume jetting. (additional acid does not need to be ordered as remaining 40 bbls will be sufficient for stimulation later in the job) c. If this is unsuccessful then POOH and pick up down jet nozzle. d. -or- as a last resort, a motor and mill. CAUTON: In the event a motor and mill is required, ensure the wellbore has been sufficiently displaced to remove any SBG or acid as returns may need to be taken. The recommended method utilizing the motor and mill would be to make hole while suspending solids in gel and taking small bites to avoid getting stuck. If return rates are good, debris and solids may be circulated out other wise they can be bullheaded back into the formation once tools are above the top of the suspended debris. If bullheading is necessary, re-tag TD to ensure that at least the minimum depth of 9845' has been reached after any remaining solids in the sump have had time to settle out. Also note that there is a cement top at 9856'. It is critical that this cement cap remains intact, do not mill on it. 15.Once the well has been cleaned out, PUH above the perfs with the nozzle and freeze protect the coil as necessary. ..5°fo HCL W/24°l~ XYLENE PERF WASH AND STIM 16. Bullhead 120 bbls of 1% KCL down the backside at maximum rate to flush all SBG from the tubing prior to the acid job. Slowly PUH while displacing the backside volume to keep pipe moving. 17. Follow with 2 bbls of 60/40 methanol water spear and underbalance with ~ 30 bbls ~3f diesel in preparation for the acid job. This should result in ~ 100 psi WHP. • • 18. Pump down the coil with 1% KCL while preparing for acid. Once coil has been displaced with 1% KCL, perform injectivity test at 1.0, 1.5 and 2.0 BPM. Do not exceed a maximum WHP of 1500 psi. Note results in WSR. 19. Follow 1% KCL with 7.5% HCL with 20% xylene. Jet with ~ 40-50 bbls of acid across perforated interval. (SIBHT=230 Deg F). Make one up/dn pass across the entire perforated interval with 25 bbls and let acid soak for 15 to 30 minutes, depending on ambient temperature constraints. 20. Make second pass at max rate with remaining 7.5% HCL. Displace coil with 1% KCL while pulling up above the perforations to 9300' and allowing the acid to soak. 21.After soak period, pump 50 bbls 1% KCL while RBIH to over displace 7.5% HCL from the near wellbore and sump. PUH to 9300' and perform a post acid injectivity test at 1.0, 1.5, 2.0 BPM as before to understand the acid stimulation. Freeze protect coil on way OOH. Once coil is freeze protected, start loading the well for a final injectivity test. 22. Pump at least 120 bbts of 1% KCL, and once at surface perform final injectivity test as before at 1.0, 2.0, 3.0, and 4.0 BPM. Make last rate at maximum pump rate. Do not exceed 1500 psi WHP. This is the final maximum rate injectivity test to evaluate the entire job. Note results in WSR. 23. Bleed down IA to 0 psi. 24. Place well on injection if possible, notifvinq operator that the IA is fluid packed, otherwise freeze protect well and request it to be placed on injection as soon as possible. RDMO CTU.

New cement cap PBTD of 9840' cement cap. 3 S Tag cement top, dummy gun AfterWOC 3 days 4 E Add Perf 9662-9692, 9715-9740, 9752-9802 (4 runs) 5 C BH Mud Acid Job + SRT Establish injectivity into new perfs The existing Zone 2 and 3 perforations will be plugged back and the gas cap in Zone 4 opened up to take water injection for EWE pressure support. The existing perfs will be sanded back with cement cap 50' above them. This should provide enough coverage over existing perforations to prevent washout of the plugback; while keeping enough (40') rathole below the proposed perforations. In the future, the well may be recompleted in Zones 2 and 3 as a MI (WAG) well. Based on prior injection experience in EWE and elsewhere in PBU it is expected that the new perforations in the gas cap will not take water initially. Therefore, programs for a bullhead mud acid stimulation and step-rate-test are part of the conversion vJ program. Even if the new perfs do take fluid, the expected target rate for this well is 5,000 bwpd and it will need a mud acid stimulation to get injectivity rates that high in '/ upper Zone 4. A copy of the wellbore diagram, snapshot and tie-in log (CBT) are attached. Please contact Beverly Luedke-Chan at x5196 or home at 345-3161 with any questions. Sincerely, Beverly Luedke-Chan EWE Production Engineer Pre-Treatment ~. dine 1. RU slickline and drift and tag. Correct to ELM tubing tail. Sand Plu.q & Cement Cap 2. RU CT unit for sandback. Load & kill well down backside with 1% KCL water. Tag PBTD and corrected to ELM slickline tag. 3. Lay in carbolite from PBTD to window 9830-9860' ELM. 4. Allow carbolite to settle and retag sand top w/CT (pumps off). May want to pump down backside to pressure up on well prior to tagging. Spot additional carbolite as necessary to bring sand top to window of 9830-9860' ELM. 5. PUH (in case Carbolite is still settling) and mix enough cement required to bring cement cap to target of 9840'. Minimum 1 bbl. Capacity-27'/bbl in 7" 6. While mixing cement pump diesel, 60/40 MW, or crude down backside as necessary to achieve positive wellhead pressure. Estimated SIBHP is 3700 psi. 7. After cement is mixed, come on line down backside at minimum rate required to maintain positive pressure (this will help protect open perfs from cement). 8. Put foam rubber before and after cement and pump through coil to nozzle. RIH and place nozzle at 10' above carbolite top as cement exits nozzle. Lay in cement 1:1. PUH to safety. SI backside injection and monitor wellhead pressure until stable. 9. POOH filling CT voidage to maintain stable wellhead pressure. 10. Freeze protect tubing. 11. RDMO.

Coiled Tubinq Mud Acid Proc~ram and Step Rate Test Coiled Tubinq Mud Acid Proqram 1. Trap 1000 psi on the inner annulus. Monitor IA pressure during the job. . Perform an initial breakdown at maximum rate or a maximum WHP of 3000 psi. Maintain the rate for 5 minutes. Immediately shut down and record the ISIP. 3. Make multiple passes across the perfs and pump the following at maximum rate down the CT with a recommended maximum WHP of 2000 psi (*): 25 bbls 100 bbls 50 bbls 150 bbls (behind pipe) 3% NH4CI with 10% U-66 and 0.2% F103 7.5% HCI 9%- 1% HCI-HF 3% NH4CI with 10% U-66 and 0.2% F103 overflush * Go to 3000 psi during the first half of the HCI stage if necessary to establish injection. Once mud acid is at the perfs the maximum treating pressure should be 2000 psi. Afl fluids should be filtered to 3 microns. Please note the initial and final injectivity in the WSR summary. Please note the rates ,/ and pressures in the WSR when each stage hits the perfs. Please run a cable so that t~h.~e~.~,~E~ruck can record back side WHP on the treatin 4. Repeat SteF _ and wait 15 minutes. Step-Rate Test 5. Perform a step rate test at "min rate" (-0.25), 0.5, 0.75, 1, 1.25, 1.5, 2, 2.5, 3, 4, and 5 BPM if possible with filtered 2 % KCI. Do not exceed 3000 psi surface pressure. Hold the first rate for 10 minutes and the remaining rates for 3 minutes each. Note the rate and pressure at the end of each step.

Z-28 is a single 3-1/2" completion with packer. Z-28 was drilled late 1988. 9-5/8 inch intermediate casing and 7 inch liner were cemented in place. Z-28 was completed as a Zone 2 and 3 oil producer. The operator now proposes to sand back and cement cap existing perforations, then open the gas cap in Zone 4 to take water injection for EWE pressure support. 9-5/8" intermediate casing was cemented sufficiently to reach well above the eventual 7" liner top. The 7" liner was also cemented with sufficient cement to extend approximately 1000' above the liner top. A cement bond log (CBL) dated 12/08/1988 indicates adequate cement bonding throughout and above the current perforations, with good bonding extending at least to 9616'. Cement volumes and CBL response are indicative of mechanical integrity. I recommend approval of the Z-28 conversion as proposed.
