Overview, Enhanced Recovery and Reservoir Management Summary Lookout Oil Pool production and injection was initiated in October 2018. Lookout development drilling began in March 2018 with six wells completed by year-end 2018. One additional well was drilled in 2019 for a total of seven development wells (three producers and four injectors). Producer MT6-06 was the only producer fracture stimulated in March 2019. There is one additional producer drilling target in the long range plan but timing is dependent on rig utilization The ongoing development scheme premises water injection with alternating gas injection (WAG) for pressure maintenance and improved recovery. Gas injection commenced in June 2019 and WAG cycles continued through 2021. A Lookout geomodel was rebuilt in 2019 based on the data collected while drilling the development wells. Subsequent updates to the geomodel and resulting simulation model continued through 2020 based on observations and learning from dynamic production data as well as data collected from well logging campaigns. These models are used for optimization and to aid in the identification of future development opportunities and will continue to be updated as new data is collected. Reservoir Voidage Balance and Cumulative Status The tables below summarize average daily injection and production rates, cumulative fluid volumes, and voidage balance as of January 1, 2022. The cumulative I/W ratio at the end of 2021 was 0.95. The following is a summary of the Lookout Oil Pool status as of January 1, 2022. Lookout Oil Pool 2021 Daily Average Rate Cumulative Volume Oil Production 2.4 MBOPD 7.0 MMSTB Gas Production 8.4 MMSCFD 13.1 BSCF Water Production 4.6 MBWPD 4.3 MMSTB Gas Injection 5.3 MMSCFD 5.0 BSCF Water Injection 7.6 MBWPD 14.7 MMSTB 2021 GMTU Reservoir Surveillance Report Lookout Oil Pool 2021 Voidage Balance Month Monthly Injection/Withdrawal Ratio, RVB/RVB Cumulative Injection/Withdrawal Ratio, RVB/RVB January 0.67 0.96 February 0.78 0.95 March 0.93 0.95 April 1.18 0.96 May 1.08 0.96 June 0.67 0.95 July 0.93 0.95 August 0.94 0.95 September 0.98 0.95 October 0.75 0.95 November 0.83 0.94 December 1.17 0.95 Summary and Analysis of Reservoir Pressure Surveys Seven pressure surveys were performed in Lookout Oil Pool wells during 2021. See Attachment 3 for the 10-412 Report of Reservoir Pressures. Results and Analysis of Production and Injection Log Surveys, Temperature, Tracer Surveys, Observation Well Surveys and Special Monitoring There were no injection or production profile logs run in 2021. The Lookout 1 exploration well was plugged and abandoned (P&A) in March 2021. Prior to P&A a reservoir saturation tool (RST) log was run in the Lookout 1 to assess the waterflood sweep. Review of Production Allocation Factors and Issues In accordance with AOGCC Other Order 112 dated October 12, 2016, Other Order 112A dated December 22, 2016, and BLM Sundry Approval for Measurement by Other Methods dated October 14, 2016, LOP production will receive an allocation factor of one (1.0). Production allocation to individual production wells in the LOP is performed in the same manner as other CPAI North Slope fields. An allocation factor comparing actual total daily LOP production sales to the sum of individual well theoretical rates will be used to adjust theoretical well production to allocated well production. The average individual well allocation factor in 2021 is 0.91. 2021 GMTU Reservoir Surveillance Report 2 Rendezvous Oil Pool Annual Reservoir Review ConocoPhillips Alaska, Inc., (CPAI) as Operator and sole working interest owner of the Greater Mooses Tooth Unit (GMTU), submits this Rendezvous Oil Pool (ROP) Annual Reservoir Review as required by Conservation Order 793, Rule 8. Overview, Enhanced Recovery and Reservoir Management Summary Rendezvous development drilling began in April 2021 with four wells completed by year-end (two producers and two injectors). Rendezvous Oil Pool production was initiated in November 2021 and injection was initiated in December 2021. Well MT7-06 was brought online as an unstimulated producer in November 2021 for a temporary production test. Once adequate production flowrate was confirmed via the production test, the MT7 drillsite was successfully started up on December 12, 2021 with MT7-06 alone. Well MT7-01 was completed, fracture stimulated, and brought on production also in December 2021. MT7-03 water injection was initiated in December 2021 and MT7-04 was started on water injection in January of 2022. The ongoing development scheme premises water injection with alternating gas injection (WAG) for pressure maintenance and improved recovery. Gas injection is expected to commence by Q4 2022. Cumulative water injection in 2021 was 15.3 MBW. There was no gas injection in 2021. A Rendezvous geomodel is being updated as new data is acquired while drilling the development wells. Updates to the geomodel and resulting simulation model will continue based on newly acquired data from drilling, observations and learnings from dynamic production data, as well as any surveillance data collected. These models are used for forecasting and identifying optimization opportunities. Reservoir Voidage Balance and Cumulative Status The tables below summarize average daily injection and production rates, cumulative fluid volumes, and voidage balance as of January 1, 2022. The cumulative I/W ratio at the end of 2021 was 0.04. Water injection and voidage replacement are low in 2021 due to production coming online for 1.5 months prior to starting up water injection and water injection only online for 3 days in 2021. The following is a summary of the Rendezvous Oil Pool status as of January 1, 2022. Rendezvous Oil Pool 2021 Daily Average Rate Cumulative Volume Oil Production 0.5 MBOPD 186.7 MSTB Gas Production 0.9 MMSCFD 315.8 MMSCF Water Production 0.0 MBWPD 10.3 MSTB Gas Injection 0.0 MMSCFD 0.0 MMSCF Water Injection 0.0 MBWPD 15.2 MSTB 2021 GMTU Reservoir Surveillance Report 3 Rendezvous Oil Pool 2021 Voidage Balance Month Monthly Injection/Withdrawal Ratio, RVB/RVB Cumulative Injection/Withdrawal Ratio, RVB/RVB January 0.00 0.00 February 0.00 0.00 March 0.00 0.00 April 0.00 0.00 May 0.00 0.00 June 0.00 0.00 July 0.00 0.00 August 0.00 0.00 September 0.00 0.00 October 0.00 0.00 November 0.00 0.00 December 0.04 0.04 Summary and Analysis of Reservoir Pressure Surveys Four static pressure surveys were performed in Rendezvous Oil Pool wells during 2021.

Results and Analysis of Production and Injection Log Surveys, Temperature, Tracer Surveys, Observation Well Surveys and Special Monitoring There were no injection or production profile logs run in 2021. Review of Production Allocation Factors and Issues In accordance with AOGCC Other Order 148 dated December 19, 2018 and BLM Sundry Approval for Oil Measurement by Other Methods and Redundancy Verification of Oil Measurement Secondary Pressure and Temperature Instruments Greater Moose's Tooth Unit (Rendezvous) dated July 1, 2019, ROP production will receive an allocation factor of one (1.0). Production allocation to individual production wells in the ROP is performed in the same manner as other CPAI North Slope fields. An allocation factor comparing actual total daily ROP production sales to the sum of individual well theoretical rates will be used to adjust theoretical well production to allocated well production.
