French, Chair Alaska Oil & Gas Conservation Commission RECEIVED 333 W. 7th Avenue, Suite 100 Anchorage, Alaska 99501-3539 JUL I 0 2017 AOGCC 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.

,'..1) 14 �r''�' Anchorage, Alaska 99501-3539 Re: 2015 Annual Disposal Report for the 14-31 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 14-31 wellbore. These disposal operations are governed by AOGCC Disposal Injection Order#23 issued 08/09/01. 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 14-31 well were essentially produced water from the Ivan River, Pretty Creek, and Lewis River fields. • The average monthly injection volume into IRU 14-31 during the reporting time period was 63 barrels/month (^'2.1 barrels/day). • The average injection pressure during injection was 1,103 psig and the maximum injection pressure was 1,614 psig which is below the permitted 5000# maximum injection pressure. • Injection rates never exceeded 1.0 BPM on any given day. These injection rates and pressures are lower than the rates estimated to fracture through confining zones. • Injection is contained within receiving intervals by confining Iithologies within the Sterling formation, cement isolation of the wellbore, and the operating conditions.

Mr. Guy Schwartz Alaska Oil & Gas Commission RECEIVED n_ 333 W 7th Avenue, Suite 100 Anchorage, Alaska 99501-3539 JUL 0 1 Zuij AOGCC Re: 2014 Annual Disposal Report for the 14-31 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 14-31 wellbore. These disposal operations are governed by AOGCC Disposal Injection Order#23 issued 08/09/01. 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 14-31. A MIT is required every two years. • In 2014 the fluids injected into the IRU 14-31 well were essentially produced water from the Ivan River, Pretty Creek, and Lewis River fields. • The average monthly injection volume into IRU 14-31 during the reporting time period was 18 barrels/month (^'2.1 barrels/day). • The average injection pressure was 951 psig and the maximum injection pressure was 1309 psig which is below the permitted 5000# maximum injection pressure. • Injection rates averaged exceeded 0.05 BPM on any given day. These injection rates and pressures are lower than the 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.

Here are my opinions. 1) Finding 18 basically restates what was contained in the application. It particularly references the workover program planned at that time and then includes a produced water volume likely developed for some unstated time into the future. It is possible that these estimated volumes are also linked to the "frac study" where different rates and injection durations were analyzed. You are correct that there is no volume limit stated in the rules. For class II injection, I don't believe that the Commission has specified a volume limit in the orders I have worked on and clearly no volume limit is specified within these rules and there is no volume limit specified in the regulations. Chevron does need to keep track of the cumulative volumes since there are comments regarding the proximity of other wells at IR and a statement regarding the potential size of the waste plume. Monitoring the offset wells' annular pressures was required so that any potential communication would be identified. If the total volume were to approach the estimates, which you say is unlikely, it might be appropriate to reexamine the frac study, however monitoring the annular pressures should provide information to demonstrate continued integrity. 2) I believe that Chevron will need to do both the monthly reporting and the annual report regardless of what waste is injected. The monthly reporting is pretty well standard for production and injection projects. Annual reports are pretty well standard as well and such reports is something that Jim Regg looks for as he oversees the Class II program. I hope these comments answer your questions. Call or message with anything further. Tom Maunder, PE AOGCC Greenstein, Larry P wrote, On 8/9/2006 2:41 PM: Sorry to hear about the teleconference.

I of2 8/10/200610:17 AM believe we are about half way there or so on the 'oilfiela waste' and 1/250th of the way on the PW. We are going back over to do somemore CT work on three or four wells that will be generating somemore of the oilfield wase type of fluid (nowhere near 15000 bbls though). The limit was not part of the Rules listed at the end. I'm not worried about the PW component at this time, but people are asking how firm is this estimated limit for oilfield waste in the findings when it is not listed in the Rules?? Do we need to firm up our running total of this type of fluid to make sure we stay away from this estimated maximum limit?? 2) If we use the well for somemore of this oilfield waste type fluid, does the normal monthly volume and pressure reporting suffice, or as part of Rule 44, do we need a special annual report evaluating the performance of the disposal operation' done next July 1?? This is not a grind and inject project, just some desanded cleanout fluids. Any performance issues that might arise this fall would lead to us talking with you and dealing with them at that time. Thanks Tom for listening. I'll be in the office tomorrow morning also if you would like to discuss.

DIO 23.001 Mr. Larry Greenstein ~'~~~ ,1AN ~ ~ 20G~ Unocal Alaska P.O. Box 196247 Anchorage, AK 99519-6247 RE: Disposal Injection Order 23-Ivan River Unit Well 14-31 (175=008) Request to Change Mechanical Integrity (MIT) Interval Dear Mr. Greenstein: By letter dated March 31, 2004, Unocal requested an Administrative Approval under Rule 6 of Disposal Injection Order No. 23 to change the interval between Mechanical Integrity demonstrations (MIT) for the {van River Unit Well 14-31 (175-008) from annual to once every 4 years. Unocal's basis for the request is that the well is used intermittently and a 4-year test interval is specified for other intermittent service disposal wells. Unless superseded by a conservation order, 20 AAC 25.252 (d) requires that the mechanical integrity (MI) of a disposal well be demonstrated at least once every 4 years as specified in 20 AAC 25.412 (c). DIO No. 23 was issued March 9, 2001. In Rule 4, the MIT interval specified was 1 year and in addition to the standard inner annulus pressure test a temperature log was required. Findings in the order file indicate the annual MIT frequency was specified because of close proximity to 2 production wells on the pad. Finding 14 of DIO No. 23 indicated IRU well 13-31 is 114' north and IRU well 44- 36 is 342' north of the disposal well at the top of the injection interval. Unocal has disposed of Class II wastes in accordance with DIO No. 23 from September 9 -November 27, 2001 and July 19 -August 11, 2002. A successful pressure MIT was performed in advance of each injection and a temperature log was obtained August 14, 2002. Approximately 39,000 barrels of waste were injected at about 1.5 bpm and 2000 psi. The rate and pressure correspond to the fracture initiation pressure determined by the infectivity test performed in June 2001. The temperature log showed cooling reversals at about 3050' and and in the perforated interval at 3190' md. The temperature plot appears to validate Finding 22 of the injection order that the planned disposal will not "... reach or • • DIO 23.001 June 1, 2004 Page 2 of 2 penetrate the confining interval at 2945' and". Aquifer Exemption Order No. 6 exempts aquifers between the measured depths of 2500' - 3450'. After mid 1999, MIT intervals were specified at 2 years in 5 of the 7 orders issued on disposal wells. The basis for the decreased test interval is to increase scrutiny of wells that inject solids from waste grinding operations. Ivan River 14- 31 is approved for the disposal of liquid and ground solid waste. Intermittent operation has not been a consideration with regard to the MIT interval. A temperature log has not been required in the other orders, however none of the other disposal wells have wells in such close proximity to the disposal well. Disposal of liquefied solids slurry° is accomplished via fracturing the receiving formation (Finding 21). A temperature log after slurry is pumped is a valid method to confirm the slurries are confined to the receiving formation. Surveillance of offset well annular pressure is the best method to identify slurry breakthrough to a nearby well. The diagnostic information provided by Unocal indicates that the wastes disposed have been contained as designed and in accordance with 'the requirements of DIO No. 23. Increasing the time interval between MIT demonstrations should not result in an increased risk of contaminating fresh water provided future disposal operations are conducted as required by the DIO. Unocal has not requested modification of any other rule in the Order. Now therefore, as provided by Rule 6 of DIO No. 23, it is Ordered that: 1. When disposal operations are resumed, Unocal shall perform an MIT and thereafter at intervals of not more than once every 2 years. 2. A temperature log will not be routinely required, except when operating parameters or offset well annular pressures indicate liquefied slurry may be leaving the confined receiving interval; or; if requested by the Commission. i dated June 1, 2004. /~ ~-- ~~ /~' ~' ~ U-- ~ ~; ;; ~:., f' Daniel T.

Unocal, requests that Rule #6 of Disposal Injection Order #23 for the Ivan River Unit well 14-31 be used to provide the administrative relief clause to authorize the following wording change within Rule #4 - Monitoring Program. Remove the words - "An annual report evaluating the performance of the disposal operation, including an annual MIT and temperature log must be submitted by July 1 of each year." Replace with the sentences - CIA schedule must be developed and coordinated with the Commission that ensures the tubing-casing annulus is pressure tested at least once eveI}' 4 years. The casing must be tested at a surface pressure of 1500 psi or 0.25 psi/it multiplied by the true vertical depth of the packer, whichever is greater, but may not be subjected to a hoop stress greater than 70% of the minimum yield strength of the casing. The test pressure must show stabilizing pressure and may not decline more than 10% within thirty minutes. The Commission must be notified at least twenty-four (24) hours in advance to enable a representative to witness pressure tests." All other reporting and monitoring requirements for this well will remain in effect. The IRU 14-31 well is an intermittent Class II water disposal well and, so far, has been used for water disposal, safely handling a total of around 40,000 bbls of fluid. The well has been shut-in since the last injection cycle in October of 2002. This well has passed all previous MITs performed. The well will be asked to handle more of the day to day produced water disposal function for the West Side gas fields as the Lewis River Unit 0-1 well is phased out of service. Similar to Granite Point Field GPP 44-11 (0\0 #10, Rule #2 dated June 16, 1995), and Granite Point State 17587 #3 (010 # 19, Rule #3 dated July 6, 1999), both intermittent Class II disposal wells which were regulated to demonstrate tubing/casing annulus mechanical integrity every 4 years, Unocal believes IRU 14-31 can safely be utilized as a Class II disposal well with a MIT frequency of every four years.

The IRU 14-31 well is an intermittent Class II water disposal well authorized and regulated by Disposal Injection Order No. 23, dated August 9, 2001. The listed MIT frequency is annually. As of now, this well has been used for water disposal four times, handling a total of around 40,000 bbls of fluid, with the last injection occurring in October of 2002. The well has been shut- in since that time. This well has passed all previous MITs. Similar to the Lewis River Unit well 0-1, also an intermittent Class II disposal well (010 #6 dated May 11, 1989), which was regulated to require a MIT every four years, Unocal believes IRU 14- 31 can safely be utilized as a Class II disposal well with a MIT frequency of every four years.

That is exactly what was going on last October. The reserve pit clean up (grind & inject) shut down then. The normal water production from all the wells at Ivan River is collected in a plastic tank on the pad. Once a week, or every other week, a water truck offioads what it can carry and delivers it to the plastic tanks at Lewis River D-1 disposal pad. After enough volume collects at Lewis River D-1 pad, the operator starts up the pumps and pushes the water into the D-1 disposal well. The D-1 well also handles the water, if any, from Pretty Creek #4 as well as the other Lewis River wells. Hope this is what you were looking for Tom. Larry ..... Original Message .....

Gdnding and injection was re. initiated July 19, 2002 and continued to August 11, 2002. A total of 31,870 bis have been injected to date. The injected volume consists of slurried cuttings, drilling mud, completion fluids and flush waters generated from the ddlling of local wells PCU No. 4 and LRU C-1 during the 2001 Drilling Program. The injection pressure has averaged 1984 psi at a rate of 1.5 BPM. The attached temperature survey indicates the near-surface effects of circulating heated glycol in adjacent pad wells to a depth of about 1500 feet. Between 1500 feet and 2750 feet, the profile shows a gradient of 0.59 psi/100 feet of depth. Below 2750 feet, the effect of injecting cold fluids causes a gradient shift to the left. The temp curve plots as anticipated, but over all the entire curve is shifted left or is cooler than one may anticipate. Beyond that the log does not appear exceptional. AS I believe you have heard, the Environmental group intends to de-water tO some extent the Ivan River Pit. They are planning tO remove the pit (next year I believe) and want to lower the water level in the pit to help them with their technical plans. It is anticipated that they could inject between 5,000' bbls and 15,000 bbls depending on Fish and Game Permit expiration for the project. Once you have reviewed the attached, please call me at 263-7657 or (907) 252-3923.

June 22,2001 Ms. Wendy Mahan Alaska Oil and Gas Conservation Commission 333 West 7th, Suite 100 Anchorage, Alaska .99501 Dear Wendy: Application for Disposal Injection Order ReqUest for Additional Information Ivan River Well 14-31, Section 1, T13N, R9W, S.M. Matanuska-Susitna Borough, Alaska As discussed in the meeting yesterday with Tim Brandenburg, DOn Andrews, and Erik Graven, the following information is submitted in response to your questions concerning Unocal's application for a disposal injection order. (1) The disposal interval conflicts with top of plug in well. The log indicates good invasion between 3145'-3420' MD. We propose to perforate this whole interval if necessary. It is expected that perforations placed on top of the retainer at 3225' MD, or as deep as possible, will allow injected wastes to be pushed below the retainer, possibly to the base of the injection zone at 3420'. If necessary, a well workover could remove the retainer and cement plug currently inside the casing, thereby adding more direct access to the lower part of the interval. (Note: Unocal has requested that the injection zone include everything from a depth of 2962' MD to the unconformity at 3420' MD). (2) Why was a % mile radius around 14-31 requested, rather than the standard ¼ mile radius? If 14-31 fails, we would like to have the option to permit a new disposal well at the same location. It is likely that such a well would need to be located outside the ¼ mile radius. (3) Why were some procedural pages included in Exhibit 8? Also, following the sundry notice some hand written notes dated 718175 are included. What was actually done regarding construction on well 14-317 ;CANNEF] ~'~UG 0 ! 2003 Ms. Wendy Mahan June 22, 2001 Page 2 Exhibit 8 should consist of one page, which is the well schematic. Please discard any other pages. Exhibit 9 consists of the casing and cementing records on IRU 14-31. Exhibit 9 should include the following: Page 1 Page 2 Page 3 Page 4 Page 5 Pages 6-7 Well completion report 8/26~75 to AOGCC. Sundry notice 9-22-86 to AOGCC. Record of actual daily events describing cementing of the surface casing. Original plan for cementing surface casing. This can be discarded since it duplicates page 3. Record of actual daily events describing cementing of the 7 inch, long string. Plan to cement the 7 inch casing. This can be discarded since it duplicates page 5. (4) Well 13-31 has a DV leak. Please note there is a write-up on what occurred, and the final leak status, at the start of Section (c) 12. (5) Summarize what was disposed of down surface casing annuli and the problems that occurred. See the attached letter for details of annular disposal on the Ivan River pad. Injected wastes were exempt drilling rig fluids, mud, and cuttings from the three Ivan River wells drilled in 1992. These wastes were pumped down the annuli after being stored in a'pit for several months. (Wells drilled were 13-31,41-1,44-36). Problems occurred on two of the three wells during annular injection. As the attachment shows, after 11,686 barrels were injected through 44-36, the annulus plugged and pressured up'to 3900 psi. The problem that occurred on 13-31 is summarized at the start of section (c)12. Please let me know if you need any additional information. Thank you for your assistance.

We understand that this test is planned to assess the suitability of converting this suspended well to a Class II disposal well to support your upcoming drilling and workover program. We concur with your reasons for proposing the injectivity test. By copy of this email you have approval to conduct the planned test, subject to the following conditions. In the absence of a Disposal Injection Order (DIO), subsurface placement of fluids may be approved provided the pumped fluid does not degrade the quality of the native fluids present in the receiving formation. We understand your potential water sources are source well water and water that has collected in the reserve pit at the well site. You may meet this requirement by testing either water for Total Dissolved Solids (TDS) and comparing that determined value with the formation water TDS derived from the available logs. If the pit water is used, it would be prudent to test for hydrocarbons and assure none are detectable using the standard test. No total volume to pump is specified in the sundry application, but you are approved to pump sufficient volume that prudent engineering requires to obtain the pressure information needed. Good luck. Please pass this approval to Don Andrews. Should there be any questions, please call.

An application is pending to convert suspended well Ivan River 14-31 to a Class II waste disposal well. An injection test is necessary to determine if the disposal zone will accept fluids, mud, and possibly slurried cuttings at anticipated pressures. The well recently passed a 1500 psi mechanical integrity test and the proposed injection test will verify and support the pending disposal injection order application. Well work and the test would proceed as follows: Perforate the interval from 3180'- 3220' MD, or as deep as possible if there is fill on top fo the cement retainer at 3225' MD. Inject pit water as follows: · Step rate sequence from ½ BPM TO 6 BPM. · Record break down pressure if this occurs. · Shut well in and obtain pressure fall-off data for 3 hours or until pressure decline stabilizes.

The applicable regulation is as follows: 20 AAC 25.110 SUSPENDED WELLS (a) Upon application by the operator under 20 AAC 25.105(e), the commission will, in its discretion, approve the suspension of a well if the well (1) encounters hydrocarbons of sufficient quality and quantity to indicate the well is capable of producing in paying quantities as reasonably demonstrated by well tests or interpretive formation evaluation data; or (2) is reasonably demonstrated to have future value as a service well. For each well on the attached list of suspended wells, please provide data showing that the well meets the criteria of (1) or (2) above or advise as to your plans to abandon the well. Wells that meet the criteria of (a) above that you wish to maintain as suspended, as required by 20 AAC 25.110(e), must have well site inspections as appropriate this year prior to snow covering the locations. , Chairman c: Blair Wondzell encl bew/llunsusp 00-0146-0 61-0045-0 66-0008-0 66-0038-0 67-0007-0 67-0023-0 67-0042-0 72-0007-0 75-0008'-0 77-0017-0 78-0096-0 79-0017-0 81-0022-0 90-0041-0 90-0071-0 o _ API ~Tu-~iBER 133-10145-01 133-10144-01 283-10020-01 283-10021-00 283-20003-00 733-20018-00 733-20032-00 133-20237-00 283-20045-00 733-20300-00 733-20119-00 733-20441-01 733-20339-00 733-20302-01 733-20417-00 _ _ OPERATOR LT~ON O~L CO LT~ON O~L ~ION OIL UNZON OmL ~YNION OIL ~O~ OIL ~ION OIL U~ION OIL CO ~ION OIL CO UNION OIL UNION OIL UNION OIL CO U~ION OIL U~ION OIL U~ION OIL CO ALASKA SUSPENDED WELLS AS OF AUGUST 1994 SWANSON RIVUNIT 14-15 SWANSON RIV UNIT 43-15RD NICOLAI CK ST 1-A NICOLAI CKLTNIT 2 NICOLAI CKI/NIT 3 GRANITE PT ST 18742 9 GRANITE PT ST 18742 10 SWANSON RIVUNIT 24-33 IVAN RI--v-~RU~IT 14-31 MGS ST 17595 16 GRANITE PT ST 18742 31 G~NITE PT ST 18742 34 G~D~NITE PT ST 18742 40 TRA~ING BAY ST A-20R~ TRADING BAY U~IT M-04 _ WELL CLASS D~V DEV DEV DEV DEV DEV SER DEV DEV DEV SEI~ D~V DEV DEV D~V WELL STATUS SUSP SUSP SUSP SUSP SUSP SUSP SUSP STATUS DATE 11/08/91 8/20/91 s/14/91 9/18/91 9/02/91 9/16/89 9/29/88 4/Ol/93 8/18/75 2/05/92 10/07/88 9/20/91 4/2m/s2 4/23/90 7/03/90 SECT 16 15 29 29 2O 12 31 O4 01 31 31 31 31 04 33 TWP 08N 08N 11N 11N 11N 10N 11N 07N 13N 09N 11N 11N 11N 09N 09N 009W 009W 012W 012W 012W 012W 011W 009W 009W 012W 011W 011W 011W 013W 013W MER Health, Environmental, Safety Alaska Energy Resouri'- ~ivision Unocal Unocal Corporation 909 West 9th Avenue, RO.

If the injection facilities are to be used for wastes generated on leases in which UNOCAL has on ownership interest, or from units for which UNOCAL is the operator, a lease plan of operations approval is required from the Division of Oil and Gas.

This application was received in conjunction with an application to convert the Ivan River Unit 14-31 well to a Class II disposal well. Both applications were published for public notice in the Anchorage Daily News on March 27, 1993. Following a review of these applications with AOGCC staff, UNOCAL has elected to modify the original documents and resubmit them at a later date.

Attached is a form 10-403 requesting a change of approved program. If you have any questions please call George Buck at 263-T~8~. RECEIVED FEB - Sincerely, G.

I~ox 107839, Anchora§e, AK 99510 · Phone (907) 786-6600 September 10, 1986 Extension of Suspended Status Ivan River Unit Well No. 14-31 Stump Lake Well No. 41-33 Mr. L. C. Smith Alaska Oil & Gas Conservation Commission 3001 Porcupine Drive Anchorage, AK 99501-3192 Dear Mr. Smith: In response to your letter of July 15, 1986 concerning the suspended status of Ivan River Unit Well No. 14-31 and Stump Lake Well No. 41-33, Chevron U.S.A. Inc. as operator is requesting a time extension of the suspended status of the two subject wells. There currently is no economic market for potential gas production from these wells and surface facilities have not been installed. Ivan River Unit Well No. 14-31 was suspended on August 18, 1975. Stump Lake Well No. 41-33 was suspended on May 14, 1978. Both wells were suspended under Alaska Oil & Gas Conservation regulations and statutes which were effective at that time. The regulation that applied to both wells was Regulation No. 2106 (Temporary Abandonment) in the 1973 Oil & Gas Conservation regulations and statutes. It states "If a well is to be temporarily abandoned and no casing pulled, then, subject to approval by the Committee, the operator shall place a plug at the top and bottom of the casing in such a manner as to prevent the intrusion of any foreign matter into the well and shall leave the well full of mud." Both wells were supended and subsequent well site inspection by AOGCC personnel were done and the sites were found satisfactory. Chevron, as operator, feels that any additional well work to meet the current regulations regarding properly plugging the subject wells is unwarranted. The wells were suspended according to regulations at the time. Both wells are in a safe, non-hazardous condition. Stump Lake Well No. 41-33 is currently shut-in with eight bridge plugs isolating perforated intervals, and a 280 ft. cement plug above the top bridge plug. Ivan River Well No. 14-31 has no open perforations and a 158 ft. ~-ement plug isolating the lowest fresh water sand (3420') from the top hydrocarbon sand (5840'). It should also be noted that Well 14-31 is being reviewed as an abandoment candidate. If additional work is to be done on .Well 14-31, Chevron requests that it be delayed until after the abandonment review has been completed. Mr. L. C. Smith Alaska Oil & Gas Conservation Commission September 10, 1986 Page 2 Chevron welcomes any AOGCC personnel to inspect the well sites for location clearance at their convenience. Please contact Mr. G. R. Molesworth at 786-6638 to set up a time for these inspections, or if you have any further questions. Sincerely, M. K.

Section. i10(a) of the regulations states the Con~nission will, in its discretion, approve the suspension of a well if the well is capable of producing hydrocarbons in paying quantities or is reasonably demonstrated to have future value as a serivce well. Section 105(e) states that "[e]ach well to be abandoned or suspended must be plugged...to prevent the movement of fluid either into or between freshwater and hydrocarbon sources and to prevent all other fluid migration within the well bore." In compliance with Section 170(a) of the regulations, "It]he location of an abandoned well onshore or upon a historically stable island must be cleared within one year following well abandonment .... " Section 170(b) provides the means for an extension of time if a valid reason exsists, and the wellbore is properly plugged. We are, therefore, requesting you to submit Form 10-403, Application for Sundry Approval,. with a program whiCh will bring the status of these wells into compliance with the new regulations and provide a schedule for this summer when our field inspectors can accompany your representatives to the well sites for location clearance inspection.

Regulation 20 AAC 25.170 Thursdayj July 8, 1982 - I traveled this date to Beluga River with Bill Sieske, Chevron representative and inspected the following locations: Prett~y Creek #2 - As the attached pictures show, thiS location is clean: and free of any trash. The well sign is posted, the cellar is covered and the well head secure. There is no reserve pit at this location. It is my recommendation to the Commission that this location be accepted as a suspended location for one year from the date of this report, at which time another inspection will be performed. Stump Lake #1 - As the attached pictures show this location is level'and small areas of vegetation growing on the pad area. The cellar is open, there is no well sign, there is a 10" pipe sticking up near the cellar which was used as a rat hole for the kelly during the drilling of 'the -well and there is a drum that needs to be removed from the location. The well head is secure, the reserve pit contains water and some trash -- empty barrels and cable -- and the burn pit is empty and clean. There is a flowing freshwater well on this location and at the southeast corner of the pad a 4" plastic pipe is sticking up out of the pad and what appeared to be a buried tank. Apparently this ~as used as a septic tank during the drilling of the well. It is my recommendation to the Commission that this location not be accepted until the following work has been'.:comp!eted: .

There are two suspended wells and an abandoned well on this pad. There is a water well that is flowing a very small amount of freshwater on the location. There is an open cellar and some mud pallets on location. The reserve pit contains water and there is a small amount of cable at the south end of the pit. I recommend to the Commission that~this location not be accepted until the following work has been completed. . 2, Blind flanges or plugs be placed on well head openings. Cellar covered Well signs put on wells ' Mud pallets and cable removed from location Water well flow be diverted off location P & A marker be extended so all information bead welded on same is above ground level.

Smith Commissioner FmOM-Doug Amos Petroleum Inspector Sta' e of Alaska DATE: April 30, 1982 FILE NO: TELEPHONE NO: SUBJECT: Conduct clean-up inspec- tion on Chevron's suspended Ivan River Unit 14-31 Well. Sec 1, T13N, R~, SM. Permit No. 75-08. Thu,.r. sday, Sept. 3, 1981: I traveled this date from Anchorage to Chevron's Ivan River Unit 14-31 Well to conduct the clean-up inspection. As the attached photographs show there are three wells on the pad. The bead welded information on the well marker post was not visible, as the photos show, the post is approximately 2' above final grade. There is f drilling line in the open pit and. pallets stacked on the pad as well. The pad it's self is level and graded and clean except for the afore mentioned items. Because 'of the absence of well signs and the buried well mar'ker post I was unable to determine which of the three wells Shown is Ivan River Unit 14'13. Therefore, I recommend to the Commission that clean-up approval not be granted: to. this location until the drilling line in the pit is removed, the stacked pallets are removed and the three wells on the pad are pro- perly marked with well signs. Also that another inspection be conducted during the summer of 1982 after Chevron has completed this work. In Summary: I conducted the clean-up inspection on Chevron's suspended Ivan River Unit ell 14-31. I do not recommend that the Commission approve this location for clean-up until the debris has been removed from the pit., and pad area and the three wells on the pad have been properly marked. I also recommend that another inspection be conducted during the Summer 1982 to confirm that this work has been completed. I filled out an A.O.G.C.C. surface abandonment reportAalong with photo- graphs showing the location ~ are attached. Attachment: After researching the well files I was able to identify the three wells on this pad. The open cellar with the wellhead is Well No. 14-31, the abandonment marker .i.s for Well ¢~23-12 and the covered cellar is Well ~44-1. 02-001/~(Rev.10/79) 'Sen. I l)ia. Stc.

Gentlemen: In regard to the above referenced, regulations, your attention. is called to an attached list of wells which, according to our records, have not received a final location inspection and approval of clean up. In compliance with 20 AAC 25.170 Section (a), "~'Tithin one year of suspension or abandonment of an on- shore well", all clean up work is to be finished. Section (b) provides the means for an extension of time if a valid reason exists. Section (c) provides, for on site inspection. Consequently, we are presenting the following list of your abandoned and/or suspended wells. Many of these are now more than one year old~ and are. not in compliance with regulations. Others should have the final inspection completed this summer while weather permits. This list covers the years 1975 to date. There may be some earlier wells that also need inspec- tion. If you have any earlier wells to be inspected this sum~.'~er please inforn~ us. There.fore, we are requesting a schedule from. you for this summer when our field inspectors can accompany your representa- tives to these sites for the final clean up insI~ction. CHEVRON U.S.A. INC.

SOCAL B~lzFg.~-lq~k~r- No. 14-31 On Sunday August 17, 1975, Mr. Will Richards of SOCAL called to obtain approval to suspend their Well No. 14-31. The well had been drilled to a total depth of 10,958 feet with a plug back total depth of 10,064 feet. Seven inch casing was being run and it stopped at 7,018 feet where it was cemented in place. In an effort to reopen the hole, drill pipe was struck and operator started to cement to base of 7" casing when the entire string became cemented in. Drill pipe and cement extends to 9927 feet with top at 3510 feet being cemented all the way between these two intervals. SOCAL proposes to place a 50 foot plug over the top of drill pipe at 3510 feet and suspend the well until future time. They plan to redrill the location and may utilize this 3500 feet of hole at that time - prob- ably one to two years in the future. I gave SOCAL verbal approval for these and advised them that it would be necessary to set surface plugs if they wanted to plug and abandon the well. They advised that at this time they do not and wanted to leave it in the suspended condition. I verbally approved the proposal and told them we would not witness the plugging since a fairly large plug already existed in the hole.

Monday morning the drilling supervisor, Will Richard called and informed me that a company charter would be ready to take off from Merrill field at 6-00 AM. I met the pilot at the airfield, helped him load freight on the aircraft and we departed Anchorage, arriving at Beluga airstrip at 6'45 AM where I was met by Mr. Richard.. We drove to his Beluga fi.eld office so he could complete his morning reports with t:he Anchorage SOCAL office. We then. drove the 15 miles to .,the Ivan River location. This location had previously been used to drill two other wells. One had been plugged and aban- doned and the other completed (.photos attached). Upon arrival at the location at 8:45 AM they were not quite ready to begin testing so I took a walk around the location reviewing the activities, the location of the equipment and the condition of the pad, the berms around the reserve pit, and general housekeeping, The steel fuel tanks were located on the pad ju.st south of the drilling rig and with no berm around them {photos attached). I lat.er checked with Mr. Riciiard and asked him if Division of Lands or Fish and Game had requi'red by letter of stip- ulatio.n that the fuel containers be bermed and he said' that they were not a requirement of the operation approval {I later found a copy of Lands approval letter which verified this as true). This was a .surprise to me since this was an operational area on the tidal mud flats where any uncontrolled fuel spill could be very damaging. At 9:15 AM testing commenced on the choke manifold, piping and valves. The choke manifold consist of ten various type 'valves with attendant flanges and welded connections which included two chokes, a Swaco automatic adjustable choke and a Shaffer manual adjustable choke. All valves and connections tested to 3000 psig with no leaks until we reached the Shaffer manual adjustable choke which would not seal off in a closed position. The Choke was torn down and the valve stem and seat were cleaned and appeared to be slightly fluid cut, they were put back l~ogether and another attempt was .made to test the valve but it still leaked so replacement parts were ordered. It was first thought that replacement parts could be received prior to completing the test but when they arrived they were for a different type of valve and could not be used. New parts were ordered from a'Shaffer representative in California and would, not arrive for one or two days. A flare line was laid from the choke manifold along side the edge of the m) R63072 O. K. Gilbreth, Jr. LCSmith-Field Trip SOCAL's Ivan River Unit 14-31 -2- May 29, 1975 pad and near the drilling observation trailer house where a meter run and bypass had been installed and then on off the drill pad to a vertical flare pipe. requested Mr. Richard to test this line out to the valves on the meter run instal- lation. He agreed that this would be a safe procedure and it should be tested and upon inspecting the line there was found to be a low pressure union installed immediately where it hooked on to the choke manifold system. This union was changed for a higher pressure union and the line was filled with water and pres- sure tested to 1500 psig with no leaks, this was completed by 12:3§AM. The kill line was next pressure tested from the mud pumps to the valves adjacent to the BOP stack. These valves, were all individually tested to 3000 psig. ~e later retested two of these valves when we tested the check valve, the stand pipe valve, stand pipe, kelly hose, kelly cock, kelly and lower kelly valve. These were all tested to 3000 psig with no problems other than considerable delays in opening and closing valves and bleeding off pressures. The stand-by safety floor valve was also pressure tested at this time {7:30 PM). The blind rams were .closed and an. attempt was made to pressure up against the casing, the blind rams and the side outlet valves. The small pun~ was used and we found and obvious leak past the blind rams. After several pressure-up attempts, the BOP's were opened to inspect the blinds ram seals. One. seal appeared to have a small cut on the top si.de so new ram seals were ordered and a Shaffer repairman was flown over' from Soldotna to. tnspec~t and repair the blind rams. Before he arrived we found that we could jump the pressure up with the rig mud pumps and after ~0 psig was attained the blind rams finally' sealed and held a satisfactory test at 8:45 PM. There were several things about the procedures on this well that required an unusually long time to complete the testing. No test plug was used in the well head so we were testing against the 10-3/4" casing and the cement plug in the casing. It required considerable time to pressure-up this large 'volume of fluid with the shoal 1 pump we were using. Several hours were spent waiting for the pressure increase to the test pressure of 2500 psig. Also, to test the pipe ranis and I.iydril without a test plug required a considerable an~ount of pipe in the hole to supply enough weight to prevent the pressure from pushing the pipe up during the test so )ir.. Richard ran the bit and drill collars to. drill out the cement plug. SOCAL is using a Shaffer rotating drilling head above the Hydril which is an additional piece of BOP equipment which required testing. The crew commenced picking up pipe to run into the hole to drill n,t +hA ~ ~ ,, plua nt 1N:NO PM h,.,+ ~,, ' '' ' O. K.

Manual adjustable chokes leaks, replacement stem and seat on order. Test pressures also applied to 10-3/4" casing and cement. Operator agreed to post well sign when received and to retest ct~oke when repa i red. I left a copy of this inspection report with Will Richard and later sent the additional copy to W. D. Sauer in SOCAL's Anchorage office. We departed the loca- tion at 4:30 AM and drove back to the camp at the Beluga airstrip where ~a had breakfast. Mr. Richard ordered a plane and at 7:45 AM the plane arrived and flew me back to Anchorage where I arrived home at approximately 9:00 AM. On this field trip I went to SOCAL's Ivan River Unit No. 14-31 well and observed the BOPE test and inspected the location. Over a 15 hour period of observation and testing one valve leaked, one 'flange leaked .and a blind ram leakage were uncovered as was a low pressure union on the flare line. Operator agreed to replace the parts in the manual adjustable choke and retest the choke. The operator had also ordered a well sign and agreed to install it at the location as required.

Blowout Prevention Considerations: Potential Problems: A. Gas: The proposed well is a stepout location in a kn6wn gas field. Gas sands can be penetrated during the course of drilling this well to total depth. Gas entries into the mud column can cause serious problems. Care must be exercised at all times to prevent gas. entries by either swabbing the well or hydraul!cing the formation on trips. Rapid penetration causes an increase in mud weight and thereby increases the risk of lost circulation and Subsequent kicks. Penetration rates will be restricted. Coal beds can cause serious problems. They contain some gas, slough readily, and drill rapidly. If thick beds are encountered, reduce the penetration rate and/or circulate bottoms up. Caution should be used while drilling these beds since they slough, and cuttings tend to pack-off around the bit. This pack-off can cause lost circulation, a kick, and/or a stuck drilling string. Lost Circulation and Water Entries: There was no lost circulation or water entries reported to 9400' vertical depth in either Ivan River 44-1 or 23-].2. C. Precautions: Any kicks should be handled by our normal procedures. Drillings .crews should be made aware of these methods. Care should be exercised at all times by every member of the crew. The hole must be kept full at all times. APPROVED PROGRAM D. Special Prob!~ms: · Considerab!e hole problems[~% . ~t',~,,~. i~~ were experienced %~e~.~.l~.' ' v River 23-].2.

Very truly yours, EPW:dw · · RoWland-\ Attachment ,3 :'t. 19 iq'! OiL AND GA5 PLAN OF OPERATION IVAN RIVER UNIT WELL 14-31 BELUGA RIVER AREA, ALASKA 1. Wel~. Site and S~ttin~ The proposed surface location for well IRU 14-31 is an existing gravel pad in Section 1, T13N, R9W on the Susitna Flats. This location was used for drilling completed well IRU 44-1. The pad will require some modification to accomodate a second well. Approximately 10,000 cubic yards of new gravel will be required. This gravel will be removed from an existing gravel pit on the access road approximately 3.5 miles northwest of the well location. Application for purchase of material has been filed with the Division of Lands, and we intend using this gravel for the pad modifications contemplated. The location is situated in a treeless, grassy marsh area above high tide level. 2. Existing Roads, Bridges, and Airstrip Ail roads and bridges in this area from the Superior Landing to the south to the Ivan River 44-1 well to the north were built in the 1962- 1965 era by Standard Oil Company of California as operator for the Beluga River Unit as well as during the course of other exploratory activity. The pit proposed as a gravel source for well IRU 14-31 was also used as a source to build the existing road and location in 1965. Piling used in bridge constructionwas cut from local spruce timber south of the Beluga River. The Beluga River Airstrip was constructed during the1962-63 original field development. It will also be used in support of our proposed drilling operations at IRU 14-31. a. The road between the airstrip and the IRU 14-31 location will receive minor repairsand upgrading. b. The deck of the Beluga River bridge will be repaired and the upstream pile supported trash racks will be repaired and replaced as necessary. We propose to cut local spruce timber south of the Beluga River to use for the trash rack pile supports. c. The Theodore River bridge was in very poor condition due to trash accumulation and was removed during 1973. A new clear span bridge will be installed over the Theodore approximately 500 feet Upstream from the original bridge location in Section 34, T14N, R9W. The old bridge and approach were in an unstable oxbow por- tion of the river. Rerouted approaches will be constructed to the proposed bridge. Bridge support and wing wall piles will be steel. Stream bank or abutment protection as required will be pile supported log crib construction. Logs for this purpose will be cut from local spruce t~nber south of the Beluga River. Plan of OPeration Ivan River Unit Well 14-31 Beluga River Area, Alaska -2- d. The Lewis River bridge is in need of extensive repair, including replacement of some piles, deck sections, and approach abutments. We propose to cut local spruce timber south of the Beluga River for replacement piles in this structure. 3. Water Supply The water well drilled in support of our IRU 44-1 well will be cleaned out and used for IRU 14-31 if possible. If the well is not usable, a new one will be drilled. 4. Driling Rig We have negotiated with Kenai Drilling Company for use of Rig No. 1 to drill our proposed well. We anticipate spudding this well during December, 1974, after completing drilling well Beluga River 224-13. 5. Access to Site and Method of Supply The site is remote and is not connected to the Anchorage area by road. The Qnly access is by one or more of the following: A. BARGING TO THE SUPERIOR LANDING (STATE RESERVED AREA ADL-45327) During most of the year, barging is possible from the Kenai or Anchorage area to the Superior Landing and thence by truck to the proposed wellsiteo Use of this landing will definitely be required to drill the proposed well. Most all of the materials and supplies required to drill this well will have to be barged to the Superior Landing. We request continued permission to use the Superior Landing. We estimate operations will continue intermittently to the end of 1974. B. AIR TRANSPORT TO BELUGA AIRSTRIP The Beluga Airstrip can handle Hercules-type airplanes, and we intend using this method to move freight and other items as can be justified economically, in addition to barging. Since the rig uses diesel fuel, we will probably fly in the fuel. Sufficient hard tankage is available to eliminate con- sideration of "bladder" tanks. The rig location will be graded so that any fuel leakage will be conducted to the waste pit. Plan of Operation Ivan River Unit Well 14-31 Beluga River Area, Alaska -3- A 50,000 gallon fuel dump is established at the Beluga Airstrip at the same location as existing facilities installed in 1962. These tanks are installed in a diked area which will contain any fuel spillage or leakage. This installation was made for rig work in BRU 241-34 and drilling BR 224-13. 6. Personnel Support A camp capable of housing and feeding approximately 40 men has been installed in an area adjacent to the existing airstrip and will be our base of operations. Personnel will be flown in and out on a scheduled basis of approximately 10 days working and 5 days off. Food and other supplies will be flown in on an "as needed" basis. Sanitation facilities for the camp, consisting of a septic tank and two leach pits, have been constructed with the approval of the Anchorage Office of the Department of Environmental Conservation. A camp water well will be required, and at the time of drilling this well we will obtain biological tests andinform Department of Environmental Conser- vation with a plat and lab tests, In addition to the camp, a house trailer has been installed for Standard Oil Company supervisory personnel. 7. M_~.scellane~us RelAted Drilling Items A. The waste pit will be located, constructed, and diked as neces- sary to prevent the possibility of any seepage to the surrounding terrain or drainages. 'Upon completion of drilling activities, the waste pit will be filled, leveled, fertilized, and reseeded with natural grasses. B. Sanitary facilities at the rig location will be chemical toilets. These toilets will be emptied periodically and the material hauled and dumped into the Beluga camp septic tank. C. The proposed location is approximately 2000' from the nearest stream (Lewis River). Our proposed drilling operations should not disturb this area whatsoever° 8. Other Construction on the Site Commercial production should be encountered in IRU 14-31. This well is being drilled to aid in the determination of the fi.eld reserves and productive limits. There is no immediate market for the gas volumes expecte~ because our existing wells to the south have the capacity to supply our contractual requirements to Chugach Electric Plan of Operation Ivan River Unit Well 14-34 Beluga River Area, Alaska -4- Association. Accordingly, production facilities will not be imme- diately installed. When they are installed, the production, dehydration, and metering facilities on-site will be similar to those already installed for six existing producers'. At that time it will be necessary to install a pipeline connecting the IRU and BRU areas. At present we plan to complete the well with one produc- ing string. 9. General Corm~ents A. No unnecessary surface digging will be allowed. In the past we 'have restored construction areas and taken measures similar to the rehabilitation methods used at Swanson River. In this case, if sufficient need exists after the proposed work is completed, we intend to fertilize and reseed as necessary with natural grasses. Regrowth in the Beluga Area is rapid and does not appear from past experience to require much help except fertilizer. B. Solid wastes such as mud sacks, kitchen waste, etc., will be hauled to the central waste pit near the airstrip and buried, while other hard wastes such as drilling bits, etc., will be disposed of in the waste pit when it is closed and covered after drilling is finished.
