May 5, 2016 Hilcorp Alaska, L.L.C.'s Request to Commingle Production from the Beluga and Tyonek Gas Pools in the wellbore BCU 23 2. May 9,2016 Notice of Public Hearing, Affidavit of Publication, bulk mail list, email distribution list CONSERVATION ORDER 726 ORDERS STATE OF ALASKA ALASKA OIL AND GAS CONSERVATION COMMISSION 333 West 7th Avenue, Suite 100 Anchorage Alaska 99501 Re: THE APPLICATION OF Hilcorp Alaska, LLC for a waiver of the requirement to provide complete separation of flow streams from separate pools as specified in 20 AAC 25.210 and authorization under 20 AAC 25.215(b) for downhole commingling of production in the Beaver Creek Unit 23 well (PTD 214-093). IT APPEARING THAT: DocketNumber: CO-16-011 Conservation Order No. 726 Beaver Creek Unit Beluga Gas Pool Tyonek Gas Pool Kenai Peninsula Borough, Alaska July 18, 2016 I . By letter dated May 5, 2016, Hilcorp Alaska, LLC (Hilcorp) requested a waiver of the requirement to provide complete separation of flow streams from different pools as specified in 20 AAC 25.210 for the Beaver Creek Unit 23 (BCU 23) (PTD 214-093) well and authorization under 20 AAC 25.215(b) for downhole commingling of production from the Beluga Gas Pool (Beluga) and the Tyonek Gas Pool (Tyonek) in the BCU 23 well. 2. Pursuant to 20 AAC 25.540, the Alaska Oil and Gas Conservation Commission (AOGCC) tentatively scheduled a public hearing for June 14, 2016. On May 6, 2016, the AOGCC published notice of the opportunity for that hearing on the State of Alaska's Online Public Notice website and on the AOGCC's website, electronically transmitted the notice to all persons on the AOGCC's email distribution list, and mailed printed copies of the notice to all persons on the AOGCC's mailing distribution list. On May 9, 2016, the AOGCC published the notice in the ALASKA DISPATCH NEWS. 3. No protest to the application or request for hearing was received. 4. Because Hilcorp provided sufficient information upon which to make an informed decision, the request can be resolved without a hearing. 5. The tentatively scheduled hearing was vacated on May 31, 2016, and the period for public comments closed on June 10, 2016. No public comments were received. FINDINGS: I . Hilcorp is the operator of the Beaver Creek Unit (BCU) and the BCU 23 well, located onshore in the Kenai Peninsula Borough, Alaska. 2. The BCU 23 well is a deviated development well with an onshore surface location 1,125 feet from the north line and 1,715 feet from the west line of Section 34, Township 7 North, Range 10 West, Seward Meridian (S.M.). The bottom -hole location is approximately 1,935 feet from the north line and 1,565 feet from the east line in the same section. Conservation Order No. 726 July 18, 2016 Page 2 of 3 3. The surface and bottomhole locations of the BCU 23 well lie within Bureau of Land Management lease A028083. 4. The BCU 23 well was completed in the Beluga in December 2014 with disappointing results. Initial production was less than 350 MCF/D. Additional perforations were added to the Beluga in May 2015 but did not appreciably add to production from the well. 5. Hilcorp proposes to perforate zones in the deeper Tyonek while keeping the existing Beluga perforations open to production. 6. The pressure in the Beluga at the BCU 23 well's location was determined to be 2,615 psi, which equates to a pressure gradient of 0.33 psi/ft, during a pressure buildup test that commenced on March 19, 2016. Hilcorp expects this to be greater than the flowing pressure of any Tyonek sand that it may produce. 7. Hilcorp proposes that initially any increase in production seen by the well after the Tyonek has been perforated would be allocated to the Tyonek and that yearly thereafter a production log will be run to determine the allocation split between the Beluga and Tyonek. CONCLUSIONS: 1. A waiver of the requirements of 20 AAC 25.210 is not required because authorization to commingle production in the wellbore is addressed by 20 AAC 25.215.. 2. Allowing commingling of production from the Beluga and Tyonek should extend the economic life of the BCU 23 well and thus lead to greater ultimate recovery than if the zones were produced separately. 3. The Beluga is a relatively low permeability formation and as such is not a prolific producer. Any potential for crossflow between the Beluga and Tyonek would be minimized by the low permeability and low productivity of the Beluga. 4. Basing production allocation initially on the pre -and post Tyonek perforating of the BCU 23 well and then conducting yearly production logs thereafter will result in adequate allocation of production from those separate pools. NOW THEREFORE IT IS ORDERED: Pursuant to AS 31.05.030 and 20 AAC 25.215(b), the downhole commingling of production between the Beluga and Tyonek in the BCU 23 well is hereby approved with the following conditions: 1. For the first year production may be allocated based on the difference between the well's production pre and post perforating of the Tyonek. 2. Thereafter, a production log must be run at least once every 12 months to determine a new production allocation factor for the well. 3. Copies of all tests and logs used for determining allocation of production shall be submitted to the AOGCC within 30 days of being run. Conservation Order No. 726 July 18, 2016 Page 3 of 3 Unless notice and public hearing are otherwise required, upon proper application the AOGCC may administratively amend this order as long as the change does not promote waste or jeopardize correlative rights, is based on sound engineering and geoscience pr, s, and will 4� f 1, 0 �C�!

Issuance of the requested Order requires an exception to 20 AAC 25.215(b).' Additionally, Hilcorp requests waiver of the requirement to provide complete separation of flow streams from separate pools as specified in 20 AAC 25.2 10 . 2 On February 18, 2016, Hilcorp submitted a proposal to modify Conservation Order 237 to formally define the Tyonek. A hearing on that issue was held on Tuesday, March 29, 2016. To date, the AOGCC has not issued an order and that docket remains in adjudication. For the purposes of this comingling application, Hilcorp is utilizing the currently approved definition of the Beaver Creek Field's Beluga Gas Pool (6,370' MD to 9,650' MD in the BCU IA well); and the proposed definition of the Beaver Creek Field's Tyonek Gas Pool (8,8 86' MD to 14,518' MD in the BCU No. 4 well). 120 AAC 25.215(b) provides: Comingling of production within the same wellbore from two or more pools is not permitting, unless, after request, notice, and opportunity for public hearing in conformance with 20 AAC 25.540, the commission (1) finds that waste will not occur, and that production from separate pools can be property allocated; and (2) issues an order providing for commingling for wells completed from these pools within the field. 2 20 AAC 25.2 10 provides: A well may not be completed in more than one pool without approval of the commission. The commission will require evidence of complete separate of flowstreams from separate pools, as ascertained by a pressure test or other acceptable test conducted at the time the packers are set. Subsequently, if packer leakage is suspected, the commission will require the operator to provide proof of complete separation of the pools involved in the completions or make a packer leakage test. At least 24 hours notice must be given so that the packer leakage test may be witnessed by a representative of the commission. BCU 23 Comingling Application • Page 2 of 5 Notably, Hilcorp has submitted, and BLM has approved, a parallel application to allow the requested commingling in the wellbore of BCU 23. See Exhibit E. Background Hilcorp drilled the BCU 23 in August 2014.3 Initial perforations were not productive. In December 2014, well was brought online from new perfs in the Beluga (-250 mcf/d). A perf gun and tool string was lost in the well during the December 2014 perf add but were fished out in February 2015. Additional Beluga perforations were added in early May 2015 with a nominal increase in rate. Initial production peaked at 373mcf/d in January 2014 and has declined since. The well is currently producing approximately 100-150mcf/d. By adding perforations to the Tyonek, Hilcorp anticipates increasing production. For a comparison of well performance see Figure 2 (BCU 23 - Beluga vs. BCU 24 - Tyonek). BC 24 is located over 1,200ft south of BC 23 at the top of the Tyonek and is currently producing 3 Permit to Drill Number 214-093; API Number 50-133-20635-00. BCU 23 Comingling Application• Page 3 of 5 8.4mmcf/d out of two sands. Although duplicating BC 24 does not have a high chance of probability, our goal is to identify similar productive sands in the BC 23. 100,000 10 000 1,000 LL u_ U R m m 100 10 —BC 23 MCFPD — — BC 24 MCFPD 1 1/1/2016 1/162016 1/31/2016 2115/2016 311/2016 3M&2016 3/31/2016 4/15/2016 Production Date Figure 2: Comparison of BC 24 & BC 23 well performance. To extend the productive life of this wellbore, Hilcorp now requests permission to test potential by-passed production in the Tyonek without isolating existing perforations within the Beluga. As demonstrated below, Hilcorp's proposal to commingle production from both the Beluga and Tyonek Gas Pools will not lead to a loss of reserves or less ultimate recovery from either pool. Moreover, waste will not occur and that proper procedures will be in place to ensure that production from the Beluga and Tyonek pools are properly allocated, Discussion On March 19, 2016, Hilcorp conducted a build-up test on the BCU 23 well. After a 116 hour build up the final calculated sand face pressure was 2,615 psi and continuing to build (Figure 3) which gives a mid perf gradient of 2,615psi / 7,809ft TVD = 0.33 psi/ft. This pressure is greater than the maximum anticipated flowing tubing pressure of any of the prospective Tyonek zones. The Beluga sands are tight, but not wet, and will continue to produce at the anticipated post -perforation drawdown. BCU 23 Comingling Application• Page 4 of 5 0 ��c �� ■ice Figure 3: BC 23 tubing pressure build up, 3/19/2016 Moreover, BCU 23 is a monobore well utilizing 5-1/2", P110, 17 ppf production casing. Due to this design constraint, a dual production string cannot be used to isolate the downhole flows from the respective reservoirs. After the initial testing phase of the Tyonek is complete, any additional rate gained by the additional perforations will be attributed to the Tyonek. On an annual basis thereafter, Hilcorp proposes to run a production log across all open perforations within the wellbore. Such data will be used to meet the requirements of 20 AAC 25.215(b)(1) (requiring that production from separate pools can be property allocated). During the initial testing phase, and thereafter, all BCU 23 production associated with the Beluga will be reported, for royalty purposes, to BLM and CIRI (joint landowners) according to the allocation schedule required by the Beaver Creek Unit's Beluga Participating Area. See Exhibit A. For AOGCC reporting of production, all BCU 23 production from the Beluga will be reported as Beluga Gas Pool. Likewise, all BCU 23 production associated with the Tyonek will be reported, for the purpose of royalties, to BLM and CIRI (joint landowners) according to the allocation schedule required by the Beaver Creek Unit's Tyonek Participating Area. See Exhibit B. For AGOCC reporting of production, all BCU 23 production from the Tyonek will be reported as Tyonek Gas Pool. BCU 23 Comingfing ApplicationO 0 Page 5 of 5 Adherence to proper reporting requirements for both allocations of production and payment of royalties will ensure that the correlative rights of affected landowners are adequately protected. Conclusion Hilcorp respectfully requests that a Conservation Order be granted by the Alaska Oil and Gas Conservation Commission to permit the commingling of oil and gas production from the Beaver Creek Field, Beluga and Tyonek Gas Pools in the BCU 23 well. Further, Hilcorp requests waiver of the requirement to provide complete separation of flow streams from the two pools. If the Commission does not grant approval to commingle the two pools, Hilcorp will be unable to evaluate potential bypassed Tyonek pay in the BCU 23 wellbore If you require additional information regarding this request, please contact the undersigned at 907-777-8319 or dtaylorkhilcolp.co .
