French, Chair Alaska Oil & Gas Conservation Commission RECEIVED 333 W. 7th Avenue, Suite 1001 ���� Anchorage, Alaska 99501-3539 _., CC Re: 2016 Annual Disposal Report for the 13-31 & 14-31 Wells in the Ivan River Unit Dear Mr. French, This is the 2016 Annual Report for the UIC Class II disposal operation in the IRU 13-31 (DIO 35) and IRU 14-17 (DIO 23) wellbores. The attached plots shows that injection rates and pressures for both wells were well below the regulatory limit of 4 barrels per minute and 5000psig. Furthermore, injection and annuli pressures indicate no mechanical concerns and that the injected fluid was contained to the approved disposal zone. Specific items to note for this reporting period: • A MIT is required every two years and the last MIT was performed 6-28-16. • In 2016, the fluids injected into the IRU 13-31 and 14-31 (432 and 314 barrels, respectively) wells were produced water from the Ivan River, Pretty Creek, and Lewis River fields. • Maximum pressures in both wells during injection never exceeded 1600psig. scouse JUL 2 02017. Sincerely, Jim Young Vanessa Hughes Reservoir Engineer Reservoir Engineer Attachment 1 —IRU 13-31 Injection rates and pressures Attachment 2—IRU 14-31 Injection rates and pressures • • o s199 i o 0 N _ I .-- In O 6O *" 0 Ll 4.

Conservation Commission 11 333 W. 7th Avenue, Suite 100 SCANNED ;� ii'. fi , Anchorage, Alaska 99501-3539 Re: 2015 Annual Disposal Report for the 13-31 Well in the Ivan River Unit Dear Mr.Schwartz: This is the 2015 Annual Report for the UIC Class II disposal operation in the IRU 13-31 wellbore. These disposal operations are governed by AOGCC Disposal Injection Order#35 issued 12/09/08. The attached plot shows injection pressures are stable and do not indicate any reservoir or mechanical concerns. Specific items to note for this reporting period: • A MIT is required every two years and the last MIT was performed on July 3, 2014. This MIT was successful and witnessed by Jim Regg. • In 2015 the fluids injected into the IRU 13-31 well were essentially produced water from the Ivan River, Pretty Creek, and Lewis River fields. • The average monthly injection volume into IRU 13-31 during the reporting time period was 42 barrels (-1.4 barrels/day). Water was injected intermittently over the year causing the injection rates to fluctuate. • The average injection pressure during injections was 1,399 psig and the maximum injection pressure was 1,604 psig which is below the permitted 5000# maximum injection pressure. • Injection rates averaged never exceeded 2.5 BPM on any given day. These injection rates and injection pressures are lower than the injection rates estimated to fracture through confining zones. • Injection is contained within receiving intervals by confining lithologies within the Sterling formation, cement isolation of the wellbore, and the operating conditions. If you have any questions regarding the enclosed information please contact me at 777-8441.

1 'LW AOGCC Re: 2014 Annual Disposal Report for the 13-31 Well in the Ivan River Unit Dear Mr.Schwartz: This is the 2014 Annual Report for the UIC Class II disposal operation in the IRU 13-31 wellbore. These disposal operations are governed by AOGCC Disposal Injection Order#35 issued 12/09/08. The attached plot shows injection pressures are stable and do not indicate any reservoir or mechanical concerns. Specific items to note for this reporting period: • On July 3, 2014 a successful MIT was witnessed by Jim Regg on the 13-31. A MIT is required every two years. • In 2014 the fluids injected into the IRU 13-31 well were essentially produced water from the Ivan River, Pretty Creek, and Lewis River fields. • The average monthly injection volume into IRU 13-31 during the reporting time period was 800 barrels (-2 barrels/day). Water was injected intermittently over the year causing the injection rates to fluctuate. • The average injection pressure during injections was 1044 psig and the maximum injection pressure was 1647 psig which is below the permitted 5000# maximum injection pressure. • Injection rates averaged never exceeded 2.5 BPM on any given day. These injection rates and injection pressures are lower than the injection rates estimated to fracture through confining zones. • Injection is contained within receiving intervals by confining lithologies within the Sterling formation, cement isolation of the wellbore, and the operating conditions.

It appears that in trying to get this done quickly (as he is gone now) he missed the specific requirements you highlighted in your e- mails. These deficiencies are being sent to Chevron for completion and I will follow up with them. Hilcorp plans to submit these reports by the July 1 dates covering the previous calendar year (ie by July 1, 2013 for the 2012 calendar year) just as Chevron has been doing. Chevron was completing these reports (for DIO #28 & DIO #35) early just due to the special circumstance of the Cook Inlet Asset sale to Hilcorp. Sorry for the inconvenience.

A post-injection Temp/Press survey was run on 2/17/09, after two months of intermittent disposal injection (16,500 bbls of slurry injected). Both surveys displayed slight deviations in recorded temperature at roughly 5500'MD. This interval corresponds with the production packer in the wellbore. The temperature anomalies (a less than 2 degree shift toward higher temperature below the packer in the pre-inj survey and a 2 degree shift toward lower temperature in the post injection survey), are almost assuredly from the differential cooling/heating of tlie`tu6irig-casing annufus above the packer versus the effect of temperature on the casing only portion of the wellbore below the packer. There is no geologic factor that can explain the slight temperature anomalies noted in both surveys. A similar, slight temperature, deviation has been noted across the packer interval in other disposal wells in Cook Inlet upon closer examination of their respective temperafure surveys. 1 .~ ,. ` 'Y ~ 1!

Nothing looks out of place (cement, tubing, casing, etc) and the probable explanation will be localized cooling due to the small volume batch injection usage of the well leaving that small temp shift across the entire casing below the packer. The formal interpretation is being prepared. More info will be coming as it is completed. Please feel free to call me if there are any questions.

DIO 35.001 Ms. Sharon Sullivan Planning & Permitting Specialist k C iD - °"(S Chevron North America Exploration and Production P.O. Box 196247 Anchorage, AK 99519 -6247 Re: Disposal Injection Fluids APR0Vp DIO 35 Dear Ms. Sullivan: Disposal Injection Order (DIO) 35 approved the injection of Class II waste fluids into the Sterling formation within Ivan River Unit (IRU) Well 13 -31. On December 10, 2008 Union Oil Company of California (Union) requested clarification concerning the fluids eligible for Class II disposal injection. Union's specific request to include precipitation accumulating within production impoundment areas associated with exploration and development activities is APPROVED. In its DIO application, Union provided a partial list of fluids it considers eligible for Class II disposal injection based on an exemption to the Resource Conservation Recovery Act (RCRA), i.e., EPA Publication 530 -K -95 -003 (May 1995), Crude Oil and Gas Exploration and Production Wastes: Exemption from RCRA Subtitle C Regulations.' Included in Union's request was the broad category "other associated wastes ". Union delineates "other associated wastes" by noting the fluids are "generated in connection with oil and gas development activities" and by using phrases such as "intrinsically derived from primary field operations ". Rule 2 of DIO 35 authorizes the disposal injection of "Class 11 oil field waste fluids generated during drilling, production or workover operations." The Commission's use of the broad term "Class II oil field waste fluids" is intended to cover those fluids obviously eligible for Class 1I disposal injection (fluids returned to surface from downhole), and to allow for other fluids to be injected into IRU 13 -31 that the Commission deems appropriate on a case by case basis. The I RCRA exempt oil and gas wastes include drill cuttings, mud, produced fluids reserve pit waste, rig wash, formation materials, completion fluids, workover fluids, stimulation fluids and solids, tracer materials, glycol dehydration wastes, naturally occurring radioactive material scale slurries, precipitation accumulating within production impoundment areas, tank bottoms, production chemicals used in wells. • • DIO 35.001 December 12, 2008 Page 2 of 3 Commission agrees with Union's position that the fluids listed in the RCRA exemption are eligible for Class II disposal injection. Union operates several production pads and facilities on the west side of Cook Inlet, each with a variety of secondary containment areas designed to capture any release of solid and liquids that could result in pollution. Secondary containment areas include but are not limited to areas around drilling rigs; grind and inject equipment; drilling and production material storage; well cellars; and reserve pits. Materials within these secondary containment areas include both fluids that have been downhole or are intended to be placed in the well to accomplish a specific purpose. The volume of precipitation that collects within these areas can be significant. Recovered fluids from secondary containment areas provide some beneficial reuse (e.g., periodic flushes of IRU Well 13 -31; make -up water for injected solids -laden slurries). Confinement of fluids to the intended injection zone in IRU 13 -31 has been evaluated and is a basis for approved DIO 35. Well integrity has been demonstrated by evaluating the well construction (cement and casing). Required pressure testing of the well's tubing - casing annulus prior to injection and monitoring the well's tubing and annuli pressures during injection will confirm the well's mechanical integrity. The disposal injection of precipitation and any spilled materials recovered from secondary containment areas (including but not limited to areas around drilling rigs, grind and inject equipment, drilling and production material storage, and well cellars) into IRU 13 -31 will have no detrimental effect on the confinement of fluids. Well integrity and correlative rights will not be negatively impacted because of the proposed inclusion of the recovered precipitation and any spilled materials in the disposal injection fluid stream. Waste will also not occur because of the addition of recovered fluids from the secondary containment/production impoundment areas. IRU 13 -31 is one of two Class II disposal injection wells operated by Union on the west side of Cook Inlet. The Commission approved a similar request regarding the disposal injection of precipitation collected from various areas into IRU Well 14 -31 (administrative approval DIO 23.002, dated October 29, 2008). A consistent approach to the fluids eligible for injection in both IRU disposal wells will minimize confusion for the Union personnel. Approval applies only to this specific request and is not intended to provide for a blanket authorization to inject these or similar non - hazardous fluids down other Class II disposal wells.

Union Oil Company of California (Union), a wholly owned indirect subsidiary of Chevron Corporation, requested that the Alaska Oil and Gas Conservation Commission (Commission) issue an order authorizing underground disposal of Class II oil field waste fluids into the Sterling Formation through Ivan River Unit (IRU) Well 13 -31. The application was received by the Commission on September 8, 2008. 2. In accordance with 20 AAC 25.540, notice of opportunity for a public hearing was published in the ANCHORAGE DAILY NEWS on September 11, 2008, on the State of Alaska Online Notices on September 9, 2008, and on the Commission's Web site on September 9, 2008. The scheduled hearing date was October 21, 2008. 3. The Commission did not receive any comments, protests or requests for a public hearing. 4. The public hearing was vacated on October 20, 2008. 5. The Commission requested clarification of certain items on October 20, 2008. Union responded on November 3 and November 8, 2008 with clarifications. 6. The information submitted by Union and public well history records for IRU wells are the basis for this order. Disposal Injection Order 35 Page 2 of 8 IRU 13 -31 December 9, 2008 FINDINGS. 1. Location of Adjacent Wells (20 AAC 25.252(c)(1)) IRU Well 13 -31 is a gas development well drilled in 1992 to a total depth of 8167 feet true vertical depth (TVD) (11,575 feet measured depth (MD)). The surface location is in Section 1, Township 13N, Range 9W, Seward Meridian (S.M.) (682 feet from south line, 699 feet from east line). The bottom hole location is in Section 31, Township 14N, Range 8W, S.M.. IRU Well 13 -31 penetrates the injection zone within Section 1. Six wells were constructed to develop gas reserves within the IRU; all wells are active except for one plugged and abandoned well. Two IRU wells penetrate the proposed injection zone within a 1/4-mile radius of IRU Well 13 -31. 2. Notification of Operators/Surface Owners (20 AAC 25.252(c)(2) and 20 AAC 25.252(c)(3)) Union is the only operator and the State of Alaska is the only surface owner within a 1/4-mile radius of the proposed disposal well. 3. Geological Information on Disposal and Confining Zones (20 AAC 25.252(c)(4)) The proposed disposal injection interval lies within the Sterling Formation, and it extends from 4272 feet to 4681 feet TVD (5544 feet to 6183 feet MD) in IRU Well 13 -31. This interval consists of a series of very fine- to coarse - grained sandstone and conglomerate beds that are generally rich in metamorphic and igneous lithic grains and commonly contain tuffaceous matrix. The proposed disposal interval is divided into three major members that are each about 125 true vertical feet thick. These members are separated by intervals of interbedded tuffaceous mudstone, sandstone, and coal have an aggregate thickness of about 20 true vertical feet. Upper confinement for the disposal injection interval is provided by a stacked sequence of siltstone, mudstone, and coal that extends from approximately 4254 feet to 4272 feet TVD (5515 feet to 5544 feet MD) (i.e., about 20 true vertical feet thick). Lower confinement is provided by a sequence of coal, mudstone, claystone, and siltstone. This sequence extends from 4681 feet to 4696 feet TVD (6183 to 6207 feet MD) (i.e., about 15 true vertical feet thick). Additional upper confinement is provided by the thick sequence of mudstone and siltstone between 3469 feet and 3643 feet TVD (4290 and 4560 feet MD) (i.e., about 270 true vertical feet thick). The thick coals and abundant mudstone beds of the lowermost Sterling, between 4824 feet and 5220 feet TVD (6435 and 7030 feet MD)( i.e., about 400 true vertical feet thick), will provide additional lower confinement. 4. Evaluation of Confining Zones (20 AAC 25.252(c)(9)) The injection of drilling mud and slurried cuttings will require pressure sufficient to fracture the formation. Union used fracture modeling to predict fracture behavior for IRU Well 13 -31 disposal injection. The results were included in the disposal injection order application. Rock property information used in the fracture model was obtained from log data generated • Disposal Injection Order 35 Page 3 of 8 IRU 13 -31 December 9, 2008 during the drilling of IRU 13 -31 and other nearby IRU wells. The fracture modeling g g Y g included a base case run with the expected injection rate, slurry density, injected volume, and injection operating practice. Numerous model runs were performed — including runs simulating extreme conditions — by varying the injection rate, slurry density, and injected volume to test the sensitivity of these parameters on fracture geometry. The fracture modeling predicts maximum fracture heights up to 100 feet true vertical thickness and a maximum half - length up to approximately 1000 feet. Using injection rate, slurry density, and injection volumes that are expected to occur in IRU 13 -31, Union's fracture modeling predicts a fracture height up to 60 feet true vertical thickness and a fracture half - length up to nearly 800 feet. Commercial gas production at IRU occurs from the Tyonek, Beluga, and Lower Sterling Formations. The shallowest gas production occurs from the lowermost Sterling Formation in IRU Well 44 -36. The shallowest productive strata lie about 200 true vertical feet deeper than the base of the proposed injection interval in IRU Well 13 -31. 5. Standard Laboratory Water Analysis of the Formation (20 AAC 25.252(c)(10)); Aquifer Exemption (20 AAC 25.252(c)(11)) The Commission issued Aquifer Exemption Order (AEO) 6 on July 23, 2001 and amended it as AEO 6A on December 5, 2008. AEO 6A extends the approved aquifer exemption depth interval to include portions of the freshwater aquifers between 2340 feet and 4202 feet TVD (2500 feet and 5435 feet MD) in, and within a Y2 -mile radius of, IRU Well 14 -31, which is the reference well for AEO 6 and AEO 6A. The equivalent depth range in IRU Well 13-31 is from about 2365 feet to 4681 feet TVD (2530 feet to 6183 feet MD). IRU Well 13 -31 disposal injection will occur within the aquifer exemption area established in AEO 6A. 6. Well Logs (20 AAC 25.252(c)(5)) Log data from IRU Well 13 -31 are on file with the Commission. Union provided a type log for IRU Well 13 -31 illustrating the proposed injection and confining zones. 7. Demonstration of Mechanical Integrity and Disposal Zone Isolation (20 AAC 25.252(c)(6)) IRU Well 13 -31 produced 14.3 billion cubic feet of gas before it was shut in December 2007. The well is constructed as follows: 20 -inch conductor casing driven to 166 feet TVD (166 feet MD); 13 -3/8 -inch surface casing set at 866 feet TVD (866 feet MD); 9 -5/8 -inch intermediate casing set at 2938 feet TVD (3460 feet MD); 7 -inch production casing set at 7352 feet TVD (10350 feet MD); and 5 -inch liner installed from 7113 feet to 8167 feet TVD (10,028 feet MD to 11,575 feet MD). The well's plug -back depth is 5435 feet TVD (7400 feet MD). 1 Union will perform a well workover to pull the production tubing and packer, install a casing patch across a leaking casing collar, and reinstall the tubing and packer. The injection completion will consist of 3.5 -inch tubing run to 4260 feet TVD (5525 feet MD) ` A slickline survey of the well in June 2008 found fill above the tubing plug -back at a depth of 4770 feet TVD (5561 feet MD). Disposal Injection Order 35 Page 4 of 8 IRU 13 -31 December 9, 2008 and permanent packer installed at 4212 feet TVD (5450 feet MD), thereby establishing the Sterling Formation as the intended zone for Class II waste disposal injection. Union reports that the 7 -inch casing in IRU Well 13 -31 is cemented from surface to the 9- 5/8 -inch casing shoe at 2938 feet TVD (3460 feet MD), and from 3925 feet to 7352 feet TVD (5000 feet to 10,350 feet MD). Cement bonding in the 7 -inch casing section opposite the injection and confining layers was not evaluated during well construction. The reported cement top of 3925 feet TVD (5000 feet MD) was calculated from the volume of cement pumped and an assessment of the cement placement operation. Union plans to run a bond log from 2340 feet to 4710 feet TVD (2500 feet to 6250 feet MD) to evaluate the cement integrity adjacent to the upper confining, injection and lower confining zones prior to installing tubing and packer. A mechanical integrity test will be performed before injection commences and, after injection is begun, as required by the Commission. Union indicates it will comply with the Commission's requirements for testing, monitoring, and reporting waste slurry injection activities. 8. Disposal Fluid Type, Composition, Source, Volume, and Compatibility with Disposal Zone (20 AAC 25.252(c)(7)) IRU Well 13 -31 will be the second active waste disposal well located on the IRU drillsite. Union intends to use IRU Well 13 -31 to dispose of drilling, production, completion, workover wastes, and other associated wastes that are intrinsically derived from primary field operations. Union projects the injection volume into IRU Well 13 -31 could be as much as 1,135,000 barrels of Class II wastes over the expected life of the well. Union expects the injection to occur in daily batch volumes averaging 155 barrels and not exceeding 1000 barrels, with rates up to 4 barrels per minute. Fracture modeling evaluated the effect of injection rates up to 4 barrels per minute, injected batch volumes up to 2500 barrels per day, and fluid densities up to 10.1 pounds per gallon. No compatibility concerns relating to the injected fluids and in -situ formation fluids have been identified by Union in connection with the injection of a similar waste fluid stream into the Sterling Formation at the nearby IRU Well 14 -31. To date, Union has injected more than 45,500 barrels of Class II wastes into IRU Well 14 -31. 9. Estimated Injection Pressures (20 AAC 25.252(c)(8)) Union estimates that the average surface injection pressure will be between 1800 psig and 2800 psig. The maximum surface injection pressure could reach 5000 psig if sporadic plugging of perforations or fracture flow channels occurs. 10. Mechanical Condition of Wells Penetrating the Disposal Zone Within a 'l -Mile Radius of IRU Well 13 -31 (20 AAC 25.252(c)(12)) IRU Well 14 -31 and IRU Well 44 -36 penetrate the Sterling disposal injection zone within a '/ -mile radius of IRU Well 13 -31. Union's review of well construction records shows that Disposal Injection Order 35 • Page 5 of 8 IRU 13-31 December 9, 2008 both wells are cased and cemented to prevent the movement of injected fluids beyond the well's confinement zones. Records documenting the drilling, casing, cementing, and testing of these wells are in the Commission's files. CONCLUSIONS: 1. The 20 AAC 25.252 requirements for approval of an underground disposal application are met. 2. The Sterling disposal zone is approximately 400 true vertical feet thick. Upper confinement is provided by a stacked sequence of siltstone, mudstone and coal that is laterally continuous throughout the affected area. Lower confinement is provided by a sequence of coal, mudstone, claystone, and siltstone that is laterally continuous across the affected area. No significant faults are present in the vicinity of the proposed operations. Although these confining intervals are relatively thin, well log correlations indicate they are laterally continuous throughout the affected area. Additional upper confinement is provided by an overlying, 270 -foot thick sequence of mudstone and siltstone, and additional lower confinement is provided by about 400 feet of underlying coal and mudstone in the lowermost Sterling. 3. AEO 6A exempts from underground sources of drinking water freshwater aquifers between 2365 feet and 4681 feet TVD (2530 feet and 6183 feet MD). 4. Commercial gas accumulations are sufficiently separated and isolated from the proposed injection zone that IRU gas production should not be adversely affected by the proposed IRU Well 13 -31 disposal operations. 5. Injected fluids should be compatible with the lithology and resident water of the injection zone. This conclusion is based on operating experience and data from disposal injection within the Sterling Formation at IRU Well 14 -31 involving similar materials and performance parameters (e.g., pressures, rates, and volumes). There have been no reported compatibility issues associated with disposal injection into the Sterling Formation at other fields in the Cook Inlet area. 6. Based on the fracture modeling results, including the extreme case sensitivities considered for injection into IRU Well 13 -31, reasonable grounds exist to conclude that waste fluids should be contained within the receiving interval by the confining lithologies within the Sterling Formation, cement isolation of the well bore, and operating conditions. 7. Modeling predicts a zone of influence (i.e., waste plume area) for injected materials equal to a fracture domain potentially extending up to 1000 feet laterally from the well. An area of review within a 1 -mile radius of IRU Well 13 -31 is appropriate given the fracture modeling results. The wells penetrating this area have sufficient mechanical integrity to prevent the migration of fluids from the proposed IRU Well 13 -31 injection zone. Disposal Injection Order 35 • • Page 6 of 8 IRU 13 -31 December 9, 2008 8. Disposal injection operations in IRU Well 13 -31 as described and modeled are not expected to fracture through the confining zones. Therefore, oil field wastes injected into IRU Well 13 -31 should be confined to an isolated zone within the Sterling Formation. 9. Supplemental mechanical integrity demonstrations and the surveillance of injection operations— including baseline and subsequent temperature surveys, monitoring of injection performance (i.e., pressures and rates), and analyses of the data for indications of anomalous events —are appropriate to ensure that waste fluids remain within the disposal interval. NOW, THEREFORE, IT IS ORDERED THAT disposal injection is authorized into the Sterling Formation within Ivan River Unit Well 13 -31 subject to each of the following requirements: RULE 1: Injection Strata for Disposal The underground disposal of Class II oil field waste fluids is permitted into the Sterling Formation within IRU Well 13 -31 in the interval from 4272 feet to 4681 feet TVD (5544 feet to 6183 feet MD). The Commission may immediately suspend, revoke, or modify this authorization if injected fluids are not confined by the upper and lower confining zones. RULE 2: Fluids This authorization is limited to Class II oil field waste fluids generated during drilling, production or workover operations. RULE 3: Injection Rate and Pressure Disposal injection is authorized at (a) rates that do not exceed 4 barrels per minute and (b) surface pressures that do not exceed 5000 psig. RULE 4: Demonstration of Mechanical Integrity The mechanical integrity of IRU Well 13 -31 must be demonstrated before injection begins and before returning the well to service following a workover affecting mechanical integrity. A Commission- witnessed mechanical integrity test must be performed after injection is commenced for the first time in IRU Well 13 -31. That test must be performed when injection conditions (temperature, pressure, rate, etc.) have stabilized. Subsequent mechanical integrity tests must be performed at least once every two years after the date of the first Commission - witnessed test. The Commission must be notified at least 24 hours in advance of each such test to enable a representative to witness the test. Unless an alternate means is approved by the Commission, mechanical integrity must be demonstrated by a tubing/casing annulus pressure test that meets the following conditions: (1) uses a surface pressure of either 1,500 psig, or 0.25 psig/ft multiplied by the vertical depth of the packer, whichever is greater; (2) shows stabilizing pressure; and (3) does not change more than 10 percent during a 30- minute period. The results of all mechanical integrity demonstrations and Union's interpretation of those results shall be provided to the Commission and be readily available for Commission inspection. RULE 5: Well Integrity Failure and Confinement Whenever any pressure communication, leakage or lack of injection zone isolation is indicated by the injection rate, an operating pressure observation, a test, a survey, a log, or any other Disposal Injection Order 35 • Page 7 of 8 IRU 13 -31 December 9, 2008 evidence, the operator shall notify the Commission by the next business day and submit a plan of corrective action (on Form 10 -403) for Commission approval. The operator shall immediately shut in the well if continued operation would be unsafe or threaten contamination of freshwater, or if so directed by the Commission. A monthly report of daily tubing and casing annuli pressures and injection rates must be provided to the Commission for IRU Well 13 -31 indicating any well integrity failure or lack of injection zone isolation. RULE 6: Surveillance The operator shall run a baseline temperature log and perform a baseline step -rate test prior to initial injection. A subsequent temperature log must be run one month after injection begins to delineate the receiving zone of the injected fluids. Surface pressures and rates must be monitored continuously during injection for any indications of anomalous conditions. Results of daily wellhead pressure observations in IRU Well 13-31 must be documented and available to the Commission upon request. The conduct of subsequent temperature surveys or other surveillance logging (e.g., water flow; acoustic) will be based on the results of the initial and follow -up temperature surveys and injection performance monitoring data. A report evaluating the performance of the disposal operation must be submitted to the Commission by July 1 of each year. The report shall include data sufficient to characterize the • disposal operation, including, among other information, the following: injection and annuli pressures (i.e., daily average, maximum, and minimum pressures); fluid volumes injected (i.e., in disposal and clean fluid sweeps); injection rates; an assessment of the fracture geometry; a description of any anomalous injection results; and a calculated zone of influence for the injected fluids. RULE 7: Notification of Improper CIass II Injection The operator must immediately notify the Commission if it learns of any improper Class II injection. Complying with the notification requirements of any other local, state or federal agency remains the operator's responsibility. RULE 8: Administrative Action Unless notice and public hearing are otherwise required, the Commission may administratively waive or amend any rule stated above as long as the change does not promote waste or jeopardize correlative rights, is based on sound engineering and geoscience principles, and will not result in fluid movement outside of the authorized injection zone. Disposal Injection Order 35 • Page 8 of 8 IRU 13 -31 December 9, 2008 RULE 9: Compliance Operations must be conducted in accordance with the requirements of this order, AS 31.05, and (unless specifically superseded by Commission order) 20 AAC 25. Noncompliance may result in the suspension, revocation, or modification of this authorization and other penalties, ENTERED at Anchorage, Alaska, and dated December 9, 2008. "6 1°1-- . - ► .

WEST SIDE COOK INLET, ALASKA \.E1) Dear Commissioner Seamount: Union Oil Company of California (Union Oil), a wholly -owned indirect subsidiary of Chevron Corporation, is hereby enclosing two (2) amended Class II Disposal Injection Order applications for underground disposal of oil field wastes in Ivan River Unit (IRU) Well 13 -31. Class II exempt wastes would be injected in the interval between 5,544 and 6,183 feet measured depth (4,221 to 4,630 feet true vertical depth) in IRU Well 13 -31. The original Class II Disposal Injection Order was submitted on September 8, 2008. This amended disposal injection order application provides additional information and clarification requested by the Alaska Oil and Gas Conservation Commission (AOGCC). This application is in conjunction with Union Oil's request for a depth extension to the existing Aquifer Exemption Order No. 6 for IRU Well 14 -31, in order to capture the base of the proposed injection zone in IRU Well 13 -31. The aquifer exemption order amendment request submitted by Union Oil on July 15, 2008, was approved by the AOGCC on November 25, 2008 and submitted to the Environmental Protection Agency (EPA) for concurrence on November 26, 2008. The Aquifer Exemption Order No. 6 Amendment is currently pending approval from the EPA. Thank you for your assistance with this project. Sincerely, • A lask JAidlAva Sharon T.

At the shallower depths that are the focus of this application, the structure is nearly flat, and is unfaulted. A thick layer of glacial outwash deposits covers the surface. These sediments were deposited by high- energy braided streams and are comprised of bedload sands and gravels, interlayered with low permeability floodplain deposits consisting of clay -rich sandy silts, and shales. The thickness of these glacial deposits is difficult to determine due to their lithologic similarity to the underlying Sterling Formation, although they appear to extend down to a depth of approximately 3,100 feet MD. The sediments of the Sterling Formation were deposited by a meander belt stream system (Hayes et. al., 1976). The resulting deposits generally include fining- upward sequences of bedload conglomerates overlain by thick quartz -rich sands which are often capped by flood plain siltstone and mudstones. Because deposition was rapid as the meanders migrated across the flood plain, the siltstones and mudstones were not completely eroded. The result of this process is extensive lateral continuity of both the coarse grained and fine grained lithologies. Coals are also common and represent the vegetative cover of abandoned meanders. The effective winnowing of the high- energy channel deposits and their relatively poor consolidation creates excellent porosity and permeability in many of the Sterling Formation sands. This formation is approximately 2,000 feet thick at the Ivan River Field. Underlying the Sterling Formation are the meander belt and braided stream deposits of the Beluga Formation. This unit is comprised of fine grained sandstones, siltstones and coals, with minor conglomerates. Due to the nature of their deposition, the sands in the Beluga are much thinner than those of the Sterling Formation and they are relatively limited in lateral extent. These sands are also relatively rich in clay which decreases their permeability. The thickness of the Beluga Formation at the Ivan River Field is approximately 2,600 feet. Underlying the Beluga Formation is the Tyonek Formation. Like the Sterling Formation, these sediments were deposited in a meander belt stream system and consist of laterally extensive sandstones, siltstones, shales and coals. The Tyonek Formation is over 4,500 feet thick at Ivan River. The location of existing wells at Ivan River Field is shown on Exhibit 2. Primary gas production is from the Tyonek Formation. The IRU 44 -01 well currently produces gas from the Tyonek Formation at a vertical depth of 7,800 to 7,900 feet below sea level. Secondary gas production comes from the Lower Sterling (top at -4,848 feet TVDSS) and Beluga (top at -5,180 feet TVDSS). 5 Injection and Confining Zones As the Exhibit 3 type log and Exhibit 4 cross section illustrate, the injection is proposed in the IRU 13 -31 well into very fine- to coarse- grained sandstones and conglomerates at 5,544 to 6,183 feet MD (4,221 to 4,630 feet TVDSS). The injection zone is in sandstones above the productive Lower Sterling. These sands are shown on the IRU 13 -31 type log in Exhibit 3 and on the cross section presented as Exhibit 4. The injection sands are individually 80 to 120 feet, totaling 390 to 415 feet in thickness. The structure maps for the top of the injection zone and top of the confining zones are based on well data and seismic data mapping. The structure maps illustrate that the injection sands are part of a doubly plunging anticline and have no faulting or fracturing in the area of review. The 810 to 855 foot thick upper confining zone is part of the thick laterally extensive sands of the Lower Quaternary and Upper Sterling formations. The 175 to 190 foot thick lower confining zone is contained within the base of the Upper Sterling Formation. The coals and shales within the lower confining zone are laterally extensive within the area and act as a barrier for vertical migration of fluids. Structural maps of the upper confining zone, the injection zone, and the lower confining zone, with depths presented in TVDSS, are shown in Exhibits 5 through 7, respectively. Reservoir Properties The injection interval within the Lower Quaternary and Upper Sterling formations have average porosities of 25% to 33% with expected permeabilities ranging from 100 millidarcies to greater than 500 millidarcies. No core data or testing is available for these sands to verify the permeabilities. 6 Page 1 of 1 • i Maunder, Thomas E (DOA) From: Bonnett, Nigel (Nigel.Bonnett) [Nigel.Bonnett@chevron.com] Sent: Monday, December 01, 2008 1:18 PM To: Maunder, Thomas E (DOA) Subject: RE: Ivan River Unit -13-31 : Sundry No. 308-387 r~~-~~~ Thank you, Tom.

We were only able to wash over the 2-7/8" tubing to 6225 ft MD, due to finding cement higher than anticipated (Step 10 of the AOGCC approved 10-403). The plan was to wash over to 6250 ft MD. Subsequently, the tubing was cut at 6195 ft MD, below located coupling. We now propose to clean out, to leave 10 ft of cement on top of the 7" EZDrill Squeeze Packer, rather than the 25 ft outlined in Step 20 of the AOGCC approved 10-403. With these shallower depths, this reduction in cement on top of the squeeze packer will enable us to stay closer to the original initial planned perforation zone of 6163 - 6183 ft MD. Please advise if the above is acceptable.

We were unable to find rams to cover these tubing OD's (2.063" and 1.900"). However, we planned to have a joint of 2-7/8" tubing w/ a XO for each size sitting in the V-door in the event we were to close our rams on the well while pulling the heater string to close in on the 2-7/8" tubing. The heater string can be pulled without picking up the tubing hanger, so there is no communication between the well below the packer or to the long string and the heater string. The annulus above the packer is currently filled with glycol but we are planning to circulate out and change over to fresh water before pulling the heater string. I believe at this time the prudent plan forward would to request a waiver of the requirements outlined in 20AAC25.035(e)(1){A): (i) one equipped with pipe rams that fit the size of drill pipe, tubing, or casing being used, except that pipe rams need not be sized to bottom-hole assemblies (BHAs) and drill collars; We believe a waiver should be granted at this time because of our plan to have a joint of 2.7/8" tubing w/ a XO to the size of heater string we will be pulling can be close-in on by our current ram coverage. Following approval of the waiver, we will complete our BOP test and pull the heater string. Let me know if you need any additional information.

I do not find any discussion regarding the "Area of Review" (AOR). The AOR is a %4 mile radius of the well starting at the top of the injection zone and continuing to the bottom. The existence of any wellbores or wellbore sections in that radius needs to be determined and then the integrity of any wellbore or wellbore section needs to be assessed. 2.

This perimeter encompasses two wells: IRU 14-31 and IRU 44-36. Both wells are cased and cemented so as to not provide a conduit for injected wastes to escape the injection Zone. No correction action plans are required. Detailed information on these wells has been provided to the State. Additional copies can be provided if requested. Well IRU 14-31: Exhibit 18 includes the well schematic. The 10 3/ inch surface casing is set at 2,037 feet MD (1,960 feet TVD). Cement was recorded to the surtace and bond logging shows good bonding. The 7-inch casing was set at 7,018 feet MD (5,829 feet TVD) and cemented to 4,197 feet TVD, which is above the top of the proposed injection zone. Second stage cement was placed from 3,646 feet TVD to 625 feet TVD, thus cement is across the injection zone and both ends of the upper confining zone. This well is an active Class II disposal well that has injected 46,500 barrels to date. Well IRU 44-36: Exhibit 19 includes the well schematic. The 9 5/8 inch surface casing is set at 3,449 feet MD (2,941 feet TVD). Cement was recorded at the surtace; logging shows good bonding from 3,449 to 2,400 feet, with fair bond up to 1,600 feet. The 7-inch casing logging shows good bond up to 4,400 feet with some cement to 4,250 feet MD, the top of the logged interval. Calculations place the top of cement at 3,591 feet TVD, which is across the injection zone and very near the top of the upper confining zone. ~~~ 1rJo~~ ~aE~®~ ~`~~~! ~~ This well is an active gas producer. 38 • • Ivan Rhrer F~~ ~1i1e11 ~~~' o~ :susw ~~~ f `~ ~ 1~1i3' ,Far `~' , ~ ~~' ~~ &'f~ib'tn~p j i1-~J4" ~.~ K,~ ; Bar 3=F~ i~Jear ~ ~9A~' ~ ~' 150 _~~~ ':F Pro3~e ~'i 2849' ~2.31~21D TTC ~ ~1 ` ;Booed ~a Baker ~IJL Fie~ntry C3utide ~t ' ~~~ia~ ~ its' awed an Et~ueigzatl~n cem+~ni 'Reiner ai ~' 7 emu Fia~elt Chao ; ~rneni .Plug ~' - 3~v(3i3' B~ga ~o11or ~ ' l~ SXB ~- ~-ru~uluo 17'~ Beeo ~184b' o~ ' <(CBi. ;Ncrt C~sr~cle~ir~e) 'F#~ ~'i BHA Thal Len X29' ~" 23, ;26 ~ 2~k J~M8i1 Pr~bly on Bo~rom ~t ¶ Dom' ~ ~01~' D ~ Fish ~C36'rsi'~l3" 1'9~P, ~'~3p ~ ~' ~B~cam ~ 9i'~~' Fish ~'lN:l~. ~ I3,C;'o Len~h 38~' ?op ;l~ 734' &,~tc~m ~` F'~sh 2876' ~-~` TBt3 .& ~ ~ 'i~2" L~,P. ?cep ~ ~9 i7 B+~tarn ~ ~i~$' carrmerri Plug 7~6L10'' 982' ~ i~° Llr ~ flfl,Df1D' ~I ~Cemaent lakug 10,11' -11~~i'J' Cement Plug 10,1' - i 11,840' `TD =1 11;958' Exhibit 18: IRU 14-31 Well Schematic 38 • • I~'ao Ri~-er Chevron ~~'ell4~-36 ~ Victual C`olnpletion 9112/01 CASING A\D TL-BIG DETAIL SIZE ttT GRADE COSH ID TOP BT3I. 13-3'8° 66 Ii-55 Buttress Suface 908 9S'8" 47 N-BO Brutress Srrface 3.4+9' T" 29 F-80 Buttress 615+ Surface 7,789' ^_9 P-I10 &uKCSS 6.18+ 7.759' 8.308- Tubiuq ?.8` 6.4 L-SO Bmt SC ?

I do not find any discussion regarding the "Area of Review" (AOR). The AOR is a'/4 mile radius of the well starting at the top of the injection zone and continuing to the bottom. The existence of any wellbores or wellbore sections in that radius needs to be determined and then the integrity of any wellbore or wellbore section needs to be assessed. 2. What does it look like the spud date might be? Call or message with any questions.

Seamount Application for Sundry Approvals (Form 10-403) ivan River Unit Well No. 13-31 Commissioner Seamount: Unocal intends to mobilize coiled tubing to ivan River Unit Well No. 13-31 in order to remove a slickline fish from the welt and to re-establish production. Recent slickline efforts to remove a "pre-packed" sand screen installed for sand control has resulted in an additional fish being left in the hole. The plan is to remove the fish. and to verify the tubing is open to the Beluga 74-8 sand. if this sand fails to produce, a wireline bridge plug will be set and 20' of cement dump bailed on top of the plug after which the Beluga 73-2 and 60-2 sands will be perforated.

When I arrived the rig was fishing for a lost bottomhole assembly and Larry McAIlister (UNOCAL representative) asked if we could postpone the test until the following day since he felt they stood a good chance of recovering the fish on this trip. I agreed to this and stood by. The crew successfully recoved the fish and we tested BOPs the following day after they finished laying down the fish. Friday, .November 27, 1992: We tested BOPS after the fish was laid down. The test was completed within three hours, which is an average time for this rig. All equipment operated correctly and held its respective pressure test. The crew seemed familiar with their testing procedure and, although this is a fairly old rig, I was impressed with the operation. No failures were observed and the surrounding location was clean and orderly with good access provided. SUMMARY: I witnessed a good BOP test on Grace Rig #154 drilling UNOCAL's Ivan River #13-31 on the west side of Cook Inlet. Unocal North Americar ~*~' Oil & Gas Division Unocal Corporation P.O.

This form and the attached procedure reflect that change in procedure along with a change in the approved casing and completion procedure. Since 7" casing became stuck at 10,350' we will be running a 5" liner. We have also reevaluated our original plan to gravel pack the Tyonek sands and instead will complete the well with tubing conveyed drop off guns. If you have any questions please call me at 263-7865.

A cement bond log was run in the 9-5/8" casing from 3392' to surface showing good bond up to 2560', establishing isolation from sands above the 9-5/8" shoe. A 64 arm caliper was run and showed some casing wear throughout with the wall thickness worn from original 14/32" to an average of 10-12/32". A higher degree of wear was detected at 1500'; 33% of the nominal wall thickness was remaining. Based on this measurement the 9-5/8" casing was pressure tested to 1800 psi surface pressure with 10.6 ppg mud. The pressure test was equivalent to 80% of the calculated burst at the weak point of the 9-5/8" casing. 7" casing was then run to 10,350' (approximately 1225' off bottom) where it became stuck. The 7" stage collar was left at 2793'. The 7" casing was cemented with the top of cement calculated to'be at 5000'. After cementing the 7" casing, injection was established down the 9-5/8" x 7" annulus with the previously established surface pressure limitation of 1800 psi. A total of 72 bbls of mud was injected before the injection rate dropped below a 1/4 bbl/min. This injection rate and the pressure limitations imposed by the 9-5/8" wall thickness anomaly at 1500' make successful injection operations questionable. The attached procedure is to repair the well for injection purposes. We will cement the 9-5/8" x 7" annulus from 2590' to surface, through the stage collar at 2793'. Placing a cement plug in this annulus will isolate the casing wall thickness anomaly from pressure generated by pumping through the stage collar to the formations below the 9-5/8" shoe. This plug will be verified by running a cement bond log. This will enable us to pump drilling mud and ground cuttings down the 7" casing, out the stage collar and past the 9-5/8" casing shoe without the pressure limitation of 1800 psi. The allowable pressure would then become 4600 psi. ,D~~\J~~~I '~ ~ After the volumes of drilling mud and cuttings have been injected into the formations below the 9-5/8" shoe the injection will be terminated. The stage collar will be closed and the integrity of the 7" casing verified with a pressure test. This annulus / injection point will be used only once and not re-entered. If you have any questions please call George Buck at 263-7685. Sincerely, ush Drilling Manager RECEIVED, Ivan River 13-31 Annulus Repair Procedure: 1.

When I arrived the rig was fishing for a lost bottomhole assembly and Larry McAIlister (UNOCAL representative) asked if we could postpone the test until the following day since he felt they stood a good chance of recovering the fish on this trip. I agreed to this and stood by. The crew successfully rec(~)/ed the fish and we tested BOPs the following day after they finished laying down the fish. Friday, October 27, 1992: We tested BOPS after the fish was laid down. The test was completed within three hours, which is an average time for this rig. All equipment operated correctly and held its respective pressure test. The crew seemed familiar with their testing procedure and, although this is a fairly old rig, I was impressed with the operation. No failures were observed and the surrounding location was clean and orderly with good access provided. SUMMARY: I witnessed a good BOP test on Grace Rig #154 drilling UNOCAL's Ivan River #13-31 on the west side of Cook Inlet.

I also checked on the choke manifold and it has two remote actuated chokes and all of its compnenets are rated to 10,000 psi. Our intention is to bring cement to surface when cementing both the 13-3/8" casing strings and the 9-5/8" casing strings. Since we are planning on injecting into the 9-5/8" x 7" annulus, and have secured the proper permits, we were only going to bring cement to 5000' when cementing the 7" casing. Cement calculations: Assume gauge hole 17.5" hole x 13-3/8" casing = 1251 cu ft (cement to surf) 12.25" hole X 9-5/8" casing = 1095 cu ft (cement to surf) 8.5" hole X 7" casing = 821 cu ft (cement to 5000') If you have any questions please call me at 263-7865.
