The locations of the OKOP wells are shown on Attachment B. Currently two producers (ODSK-14 and ODSN-29 Kuparuk) and two injectors (ODSK-35Ai and ODSK-38i) are active. The ODSK-33 well is inactive due to high water cut, the ODSK- 13i well remains shut-in for long term pressure fall-off monitoring, the ODSK-41 well is shut-in due to a failed ESP (failed October 17, 2018), and the ODSN-40i Kuparuk is currently shut-in due to limited injection capacity. A rig workover to complete the ODSN- 29 Kuparuk interval and run a selective single completion concluded on September 6, 2017; tract operations were initiated on October 20, 2017, and the Oooguruk Kuparuk Participating Area was expanded on July 11, 2018 to include the associated area. The interval is currently producing at approximately 920 BOPD with cumulative production through December 31, 2018 of 571 MSTB. While the Kuparuk production has temporarily shut-in Nuiqsut production from the ODSN-29 well, the long-term plan, which requires AOGCC approval, is to commingle production from the two pools at this OU location or alternate production from each zone as the Kuparuk is much more prolific and is currently at a higher pressure than the underlying Nuiqsut in the area. Annual average daily OKOP production for 2018 was 1,578 BOPD. Total oil production during 2018 was 576,072 barrels for a total 9,358,761 barrels since field start-up. During 2018 Kuparuk River Unit seawater supply to Oooguruk was restricted to less than 5,000 bwpd for 164 days; consequently, water injection purposely targeted Oooguruk-Nuiqsut Oil Pool (ONOP) patterns in order to optimize voidage replacement. Average daily OKOP water injection for 2018 was 1,313 BWPD. Total water injection in 2018 was 479,356 barrels and 15,188,431 barrels since the start of the project. 2.0 Results and Analysis of Reservoir Pressure Surveys within the Pool Ten pressure surveys were reported from six OKOP wells during 2018; the pressure survey results are presented in Attachments C and D. Overall, the pressures in the Kalubik fault block indicate pressure stabilization due to historical voidage replacement, excluding the ODSK-41 area, which continues to show limited communication to offset injection wells. Pressures from the ODSK-13i injection and fall off test indicate the western Ivik block has relatively low transmissibility and is not in hydraulic communication with the main Kalubik block development area. Kuparuk pressures measured in the ODSN-29 Kuparuk eastern Ivik well confirmed communication with the main Kalubik fault block but not to ODSK-13i in the western Ivik fault block. Caelus Natural Resources Alaska, LLC Page 1 3.0 Results and Analysis of Production and Injection Log Surveys, Tracer Surveys, Observation Well Surveys and Any Other Special Monitoring A chemical tracer program was initiated in May 2012 and completed in 2014. Tracers were injected into ODSK-35Ai and ODSK-38i. Within 20 months of initial injection tracer concentrations were observed in ODSK-33 and ODSK-14 from ODSK-35Ai. To date, ODSK-38i tracer has only been seen in minor amounts in ODSK-33. Produced water samples for ODSN-29 Kuparuk have not shown signs of either tracer. 4.0 Review of Pool Production Allocation Factors and Issues Over the Year Production from the OKOP, ONOP, and Oooguruk-Torok Oil Pool (OTOP) is commingled at the surface into a common production line. Allocation between the pools is based on the ratio of total production for a pool to the total production for the Oooguruk Unit. The pool allocation factors for 2018 are: ONOP: 84.1% OKOP: 14.7% OTOP: 1.2% Theoretical production for individual wells for all pools is calculated on a daily basis. During 2018 wells were produced with chokes at 100% most of the time due to the capacity of the production line. Daily theoretical production for a well was calculated using the data from the most current well test and the amount of time a well was on production for a given day: MlnLit eS produced xDailyRate(BOPD)ryesre.,,=TheoreticalDailyProduction 1440 MinuteSl, day The daily allocation factor for the unit is calculated by dividing the actual total production for the day by the sum of the theoretical daily production for each individual well. Daily allocated production is assigned to each well by multiplying its theoretical daily production by the daily allocation factor. The average daily allocation factor for 2018 was 1.0542. 5.0 Reservoir Management Summary The Alaska Oil and Gas Conservation Commission (AOGCC) issued pool rules under Conservation Orders No. 645, 596 and 597 for the OTOP, OKOP and ONOP, respectively. While there is no subsurface commingling, unitized substances produced from the three oil pools are commingled on the surface. Caelus Natural Resources Alaska, LLC Area Injection Order No. 33 authorizing the injection of fluids for enhanced oil recovery in the OKOP was issued by the AOGCC in 2008 and injection commenced in 2009. OKOP production was primarily associated with the ODSN-29 Kuparuk in the eastern Ivik fault block. Performance to -date suggests a significant associated pore volume with support from the Kalubik injection wells, ODSK-35A and ODSK-38, but not with the ODSK-13 well in the western Ivik fault block (refer to Attachments C and D). Since initiating Kuparuk production from ODSN-29 there has been no change in the fall-off trend in the ODSK-13 well. Consequently, the Oooguruk Kuparuk Participating Area was expanded on ,duly 11, 2018 to include the associated area around the well on lease ADL 355036. Future development plans of the expanded area are contingent on the longer term performance from the well and evaluation of alternatives to further develop this area of the OKOP. Because the main Kalubik fault block development area is a mature flood, in a dual porosity system, with highly variable matrix permeability and open fracture networks, voidage replacement has been purposely reduced, currently at 67% cumulative voidage replacement, to minimize waterflood by-pass while stabilizing the reservoir pressure and GOR, refer to Attachment A. 'rhe estimated average reservoir pressure is currently 2,700 psi at 6,050 ft TVDss and the average annual producing GOR is 1,183 SCFISTBO (refer to Attachment E, Kuparuk Annual Reservoir Properties Report Form 10-428). As a result, the producing OKOP water oil ratio increases have slowed and oil production has remained relatively stable. A simulation model has been maintained and updated to assist in reservoir and flood management decisions in the OKOP Caelus Natural Resources Alaska, LLC Page 3 Month n Since Jan -18 Feb -18 Mar -18 Apr -18 May -18 Jun -18 fid -VA Aug -18 Sep -18 Oct -18 Nov -18 Dec -18 Totals Oil, MRS p thru 73 65 67 43 78 71 71 60 63 58 35 36 720 ATTACHMENT A: Kuparuk Voidage Balance by Month of Produced and Injected Fluids 2018 Fluids 562 386 Fluids Total Total Cum since Cum since Free Gas, Water, Voidage, Year Cum, start-up, MRS MRS MRS MRS MRS 17» 18 18 14,727 20,909 22 38 133 133 21,042 24 31 120 253 21,162 28 31 126 379 21,288 11 31 86 464 21,374 46 38 162 626 21,536 69 35 175 802 21,711 77 31 179 980 21,890 60 27 147 1,127 22,036 61 38 163 1,290 22,199 75 36 170 1,459 22,969 44 23 102 1,562 22,471 45 26 106 1,668 22,577 562 386 Fluids 0 479 479 (Injection - Production) Total Cum since Gas, Injection, Year Cum, start-up, MRS Water, MRS MRS MRS MRS i Since Start -Up thru 2017» -115 14,709 18 18 18 14,727 18 18 36 14,745 16 16 52 14,761 15 15 67 14,776 14 14 81 14,790 37 37 118 14,827 103 103 222 14,931 48 48 270 14,979 43 43 312 15,022 28 28 341 15,050 84 84 425 15,134 55 55 479 15,188 0 479 479 (Injection - Production) Net Cum since Injection, Year Cum, start-up, MRS MRS MRS -6,200 -115 -115 -6,315 -102 -217 -6,417 -110 -327 -6,527 -71 -398 -6,598 -147 -545 -6,745 -138 -683 -6,883 -76 -759 -6,959 -99 -857 -7,058 -120 -977 -7,178 -142 -11119 -7,319 -18 -1,137 -7,337 -52 -11188 -7,389 -1188 Caelus Natural Resources Alaska, LLC Page 4 C) ADL389960 O, ADL355037 ADL355039 N W+E S 0 0.5 , 1 2 ATTACHMENT B: Map of Kuparuk Well Locations ADL389956 ADL389965 i � G ADL389959 G' ADL389958 ODSK-13 O)SK-35Ai OD:; K-14 ©7S'V-29 ODSK-38 • ADL355d36 QK-33 ODYN -406 D SK ►; — s i ADL355038 ��■� Miles 3 4 ADL379301 A -L389954 JADL389953 ADL389950 IADL389949 ADL389952 ADL389951 t Legend i Kuparuk Poo!

During 2018 ONOP rig workover operations were completed on ODSN-02 and ODSN-04. The workovers were conducted to install gas lift completions to replace the ESP completions in the wells, one of which had failed prematurely (ODSN-02). The workover program was completed in October 2018. The locations of the existing ONOP wells are shown on Attachment B. Within the central Kalubik fault block, ODSN-01A, ODSN-24, ODSN-25, ODSN-31, ODSN-36, ODSN-37 and ODSN-42B continued to produce in 2018. The wells are supported by water and gas injection in ODSN-19i, ODSN-26i, ODSN-32i, and ODSN- 34i. Production from ODSN-01A was occasionally cycled on and off during the year to manage voidage replacement and the producing gas oil ratio (GOR). ODSN-10, ODSN-16, ODSN-17 and ODSN-18 continued to produce throughout 2018 in the Colville Delta fault block, supported by water and gas injection in ODSN-23i and ODSN-151. Offtake from the ODSN-10 well has been restricted to manage voidage replacement and the producing GOR. Within the northern Ivik fault block, ODSN-02, ODSN-04, ODSN-06, and ODSN-28 continued to produce in 2018. ODSN-29 Nuiqsut production remained shut-in for evaluation and testing of the Kuparuk in the area from the well via a selective single completion installed in 2017. The long term plan, which requires AOGCC approval, is to commingle production from the two pools at this location or alternate production from each zone as the Kuparuk is much more prolific and is currently at a higher pressure than the underlying Nuiqsut in the area. Production is supported by water injection in wells ODSN-03i, ODSN-07i and ODSN-27i. ODSN-22 and ODSN-43 in the southwestern ONOP continued to produce throughout 2018 supported by water and gas injection in ODSN-48i. In order to manage voidage and producing GORs production from the pattern has been restricted during the year by alternating production cycles from the two wells. Annual average daily ONOP production during 2018 was 9,002 BOPD. Total oil production from the ONOP during 2018 was 3,285,556 barrels and is 26,609,103 barrels since field start-up thru 2018. The annual average producing GOR and watercut were 1,204 SCFISTBO and 16%, respectively. Annual average daily ONOP injection during 2018 was 8,173 BWPD and 3,440 Mscfd. Cumulative water injection in the ONOP during 2018 was 2,982,964 barrels and 21,661,486 barrels since the start of the project. Total gas injection in the ONOP during 2018 was 1,256 MMscf and 10,817 MMscf since the start of the project. Throughout 2018, water and gas injection continued in the ONOP; however, during 2018 Kuparuk River Unit seawater supply to Oooguruk was restricted to fess than 5,000 bwpd for 164 days which reduced overall ONOP voidage replacement. Attachment A details the 2018 voidage balance for the ONOP. Caelus Natural Resources Alaska, LLC Page 1 2.0 Results and Analysis of Reservoir Pressure Surveys within the Pool Thirty-one pressure surveys were reported from 20 wells. The details of the pressure tests and interpretation can be found in Attachments C and D. The estimated average reservoir pressure is currently 2,650 psi at 6,350 ft TVDss (refer to Attachment E, Nuiqsut Annual Reservoir Properties Report Form 10-428). 3.0 Results and Analysis of Production and Injection Log Surveys, Tracer Surveys, Observation Well Surveys and Any Other Special Monitoring Well surveillance equipment was placed in the liners of seventeen Nuiqsut wells during the initial completions. The systems are in-place to assess production profiles and continuity along the lateral via target fluid tracers, which are monitored and analyzed by collecting surface fluid samples during restarts and over time. The tracers have recently been used to assess hydraulic connectivity along the laterals to evaluate the need for coil tubing interventions to clear any sand or debris blocking the flow path. The tracers will also be used, where available, to help diagnose water breakthrough in the future. Coiled tubing conveyed gamma ray logs were recorded in four wells, ODSN-01 A, ODSN- 22, ODSN-37 and ODSN-43, to identify initial breakthrough intervals along the laterals. The gamma ray log detect increased activity in areas with precipitated barium sulfate scale indicative of seawater breakthrough. The data has been incorporated in the geologic description and the simulation modeling. The information may be helpful in diagnosing and treating possible injection thief intervals. An extended reservoir surveillance and remedial program is ongoing in the ODSN-03i pattern which had early water injection breakthrough in both offset producing wells, ODSN-02 and ODSN-04. In July 2016 plugs were placed in the lateral of ODSN-03i to isolate suspected thief zones and the response was monitored in the ODSN-02 and ODSN-04 wells. A thief zone was identified in ODSN-03i in 2017 and injection restored to the lateral. Remediation of the ODSN-03i thief interval using a conformance gel treatment was completed in August, 2018; injection was reestablished and a log to assess the change in infectivity along the lateral is planned for 2019 using coiled tubing.

Daily allocated production is assigned to each well by multiplying its theoretical daily production by the daily allocation factor. The average daily allocation factor for 2018 was 1.0542. 5.0 Reservoir Management Summary The Alaska Oil and Gas Conservation Commission (AOGCC) issued pool rules under Conservation Orders No. 645, 596 and 597 for the OTOP, OKOP and ONOP, respectively. While there is no subsurface commingling, unitized substances produced from the three oil pools are commingled on the surface. Area injection orders authorizing the injection of fluids for enhanced oil recovery in the Oooguruk-Torok, Oooguruk-Kuparuk, and Oooguruk-Nuiqsut reservoirs were issued by the AOGCC as Area Injection Orders No. 37, 33 and 34, respectively. Injection commenced into the ONOP in 2009. During 2018 the ONOP Under -Saturated Water -Alternating -Gas (US -WAG) reservoir management included maximizing voidage replacement and managing producing gas oil ratios by cycling producing wells on and off production where possible operationally. The Caelus Natural Resources Alaska, LLC Page 3 current cumulative voidage replacement ratio is at 52% which is consistent with ratio of injection wells to producing wells and the overall ONOP pattern layout. In general producing wells in the more mature flood areas have seen GOR stabilization, stabilized or increased oil production and some water breakthrough as expected. The average ONOP producing GOR for 2018 was 1,204 SCFISTBO which is slightly lower than the 1,264 SCFISTBO GOR in 2017. The 2018 average ONOP watercut was 16%. Flood throughput and reliable water supply are important to long-term ONOP recovery. Consequently, Caelus is moving forward with a seawater injection system (SWIS) enhancement project, increasing the available injection supply and pressure, and incorporating alternative stimulation techniques. The SWIS project, which will bypass KRU CPF-3 and consistently supply ODS with up to 25,000 bpd of seawater, increase water injection reliability, and avoid produced water injection at ODS, has been approved and is under construction with start-up planned in the fourth quarter of 2019. In association with the SWIS project, water injection supply pressures will be boosted to 3,500 psi from 2,800 psi. High pressure testing in 2018 on four ONOP injection wells, ODSN-261, ODSN-27i, ODSN-32i and ODSN-34i, demonstrated an average four -fold increase in injectivity with no containment or well integrity concerns consistent with historical performance and modeling. The ONOP fracture containment model for EOR operations has been updated to incorporate performance to -date and the results of the high pressure injection tests. An application to modify Area Injection Order 34 Finding 13, which currently limits the surface injection pressure to less than 2,900 psi, to increase the pressure limit to 3,500 psi is in progress. Additionally, ODSN-26i was stimulated using a coil tubing placed treatment consisting of surfactant and solvent mixtures and downhole chlorine dioxide (CI02) generation as an oxidizing, biocide treatment to remove near wellbore plugging. Efficacy of the treatment is under evaluation but the initial results are encouraging. Individual well and pattern surveillance data will continue to be collected to monitor performance and improve recovery. A simulation model has been maintained and updated to assist in reservoir and flood management decisions in the ONOP Caelus Natural Resources Alaska, LLC Page 4 ATTACHMENT A: Nuiqsut Woidage Balance by Month of Produced and Injected Fluids 2018 Produced Fluids Caelus Natural Resources Alaska, LLC Total Injection, Total Gas, Cum since Injection, Oil, Free Gas, Water, Voidage, Year Cum, start-up, Month MRS MRS MRS MRS MRB MRB Cum Since Start-up thru 2017» 26,649 0 399 48,934 Jan -18 398 430 61 889 889 49,823 Feb -18 363 403 57 823 1,712 50,645 Mar -18 351 403 64 818 2,530 51,464 Apr -18 247 240 48 535 3,065 51,999 May -18 321 375 57 753 3,818 52,752 Jun -18 298 304 56 659 4,477 53,411 Jul -18 277 311 43 630 5,107 54,041 Aug -18 2S8 366 45 699 51806 54,739 Sep -18 294 354 49 697 6,502 55,436 Oct -18 295 307 35 638 7,140 56,074 Nov -18 304 377 46 727 7,867 56,801 Dec -18 309 373 50 731 8,599 57,532 2018 Totals 3,746 4,243 611 8,599 Caelus Natural Resources Alaska, LLC Net Total Injection, Cum since Gas, Water, Injection, Year Cum, start-up, MRB MRS MRB MRB MRB Cum Since Start -Up thru 2017 >> -844 26,180 0 469 469 469 26,649 0 399 399 668 27,048 0 452 452 1,320 27,500 0 419 419 1,739 27,919 0 386 386 2,125 28,305 5 86 91 2,216 28,396 180 4 184 2,401 28,581 176 14 189 2,590 28,770 192 48 241 2,831 29,011 147 63 210 3,041 29,221 162 371 533 3,574 29,754 132 272 404 3,977 30,157 994 2,983 3,977 Net Cum since Injection, Year Cum, start-up, MRB MRB MRS -22,754 -420 -420 -23,174 -424 -844 -23,598 -366 -1,210 -23,964 -116 -1,327 -24,080 -367 -1,693 -24,447 -567 -2,261 -25,014 -446 -2,707 -25,460 -509 -3,216 -25,969 -456 -3,672 -26,426 -427 -4,099 -26,853 -194 -4,294 -27,047 -328 -4,621 -27,375 Page 5 ATTACHMENT B: Map of Nuiqsut Well Locations N 8i ADL389956 �� ADL3899516�, Gig G� Q3�"az oasm.ori � .. oo I ADL37.9301 ` AW89960 nE)SN ADL389959 DL 5 I .,,0- ' Q7 SN -eta oosN + j ql �/ r 4f3&N-za QOSN-try URUK t f / }.�N.26i if �� ?'•,� L389954 ADL38993 -24 1 N 7�1y -`SN37 k f.'`_ s r ti QOSN 1oC1 6 N-38,. • � 'yf E - \,,,i � ;i Qi)s �a ' �` t)L389960 ` ADL389949 410 N a5 ADL35 3 A.

A workover on ODST-39 to repair the 7" casing and to run a gas lift completion was completed on October 3, 2018; production from the well has been restored. ODST-47 is non-productive due to a mechanical failure in 2013; plans are in-place to isolate the Torok and utilize the slot for additional Nuiqsut development. Consistent with ongoing and future development plans the Oooguruk Torok Participating Area (GTPA) was revised on July 11, 2018 to remove southern acreage associated ODST-47. The two Nuna Drillsite 1 (NDS1) wells, Nuna-1 and NDST-2, are suspended pending restart of development activities. The locations of the existing OTOP wells are shown on Attachment B. Caelus continues to pursue funding for Phase 1 of the Nuna Torok project (Attachment C) which would access resources inaccessible from the Oooguruk Drill Site (ODS) in and near the Colville River Delta using extended reach drilling from NDS1. The project lies two miles north-west of existing facilities at KRU Drill Site 3S (DS -3S). During 2018 Caelus re-evaluated and continued to optimize the drilling and facility construction schedule and cost in light of lower oil prices and uncertainty in the tax structure environment. Equipment, material procurement and module fabrication are currently suspended. Annual average daily OTOP production for 2018 was 125 BOPD. Total oil production from the OTOP during 2018 was 45,767 barrels and is 907,879 barrels total through 2018. The 2018 annual average producing gas oil ratio was 1,134 SCFISTBO. Seawater injection continued in ODST-46i and the well was monitored pursuant to the rules of Area Injection Order 37 (AlO 37). Attachment F, in compliance with AIO 37, Rule 9, details the well injection pressures and injection for the report period. During 2018 Kuparuk River Unit seawater supply to Oooguruk was restricted to less than 5,000 bwpd for 164 days; consequently, water injection purposely targeted Oooguruk-Nuiqsut Oil Pool (ONOP) patterns in order to optimize voidage replacement. Torok water injection was limited to 62 days in 2018, yielding a daily average water injection rate of 748 BWPD. Cumulative water injection in the OTOP during 2018 was 46,376 barrels and 791,042 barrels since the start of the project. In 2018 no gas was injected in the OTOP. Total gas injection in the OTOP is 171 Mscf since the start of the project. Attachment A details the 2018 monthly voidage for the OTOP. 2.0 Results and Analysis of Reservoir Pressure Surveys within the Pool Nine pressure surveys were reported from four OTOP wells during 2018. The extended pressure build-ups in ODST-45A, ODST-39, and ODST-47 coupled with the ODST-46i falloff data, suggest similar levels of depletion and continuity in the ODS development area. The average OTOP pressure at 5,000 ft TVDss is estimated at 2,200 psi. Attachment D, E and F detail the surveys and relevant data. Caelus Natural Resources Alaska, LLC Page 1 3.0 Results and Analysis of Production and Injection Log Surveys, Tracer Surveys, Observation Well Surveys and Any Other Special Monitoring Extended shut-in bottomhole pressure data from ODST-39, ODST-45A, ODST-46i and ODST-47 indicate good communication in the reservoir as evidenced by the equalization of the pressures over time (see Attachments D and E). 4.0 Review of Pool Production Allocation Factors and Issues Over the Year Production from the OTOP, Oooguruk-Kuparuk Oil Pool (OKOP) and Oooguruk-Nuigsut Oil Pool (ONOP) is commingled at the surface into a common production line. Allocation between the pools is based on the ratio of total production for a pool to the total production for the Oooguruk Unit. The pool allocation factors for 2018 are: ONOR 84.1% OKOP: 14.7% OTOP: 1.2% Theoretical production for individual wells for all pools is calculated on a daily basis. During 2018 wells were produced with chokes at 100% most of the time due to the capacity of the production line. Daily theoretical production for a well was calculated using the data from the most current well test and the amount of time a well was on production for a given day: Minutes p,.O"„Cep Minutes' xDai1yRate(B4PD),,.,,,,,,, = TheoreticalDaily Production 1440 /day The daily allocation factor for the unit is calculated by dividing the actual total production for the day by the sum of the theoretical daily production for each individual well. Daily allocated production is assigned to each well by multiplying its theoretical daily production by the daily allocation factor. The average daily allocation factor for 2018 was 1.0542. 5.0 Reservoir Management Summary The AOGCC issued pool rules under Conservation Orders No. 645, 596 and 597 for the OTOP, OKOP and the ONOP, respectively. While there is no subsurface commingling, unitized substances produced from the three oil pools are commingled on the surface. Area injection orders (AIOs) authorizing the injection of fluids for enhanced oil recovery in the Oooguruk-Torok, Oooguruk-Kuparuk, and Oooguruk-Nuigsut reservoirs were i-aelus Natural Resources Alaska, LLC Page 2 issued by the AOGCC as AIO No. 37, 33 and 34, respectively. Injection commenced into the OTOP in 2012. Reservoir management included maximizing voidage replacement by maintaining injection in the ODST-46i well. The current cumulative voidage replacement ratio is at 33%. A simulation model has been maintained and updated to assist in reservoir and flood management decisions in the OTOP. A workover on ODST-39 to repair the 7" casing and to run a gas lift completion was completed on October 3, 2018; production from the well has been restored. ODST-47 is non-productive due to a mechanical failure in 2013; plans are in-place to isolate the Torok and utilize the slot for additional Nuiqsut development.
