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). No additional Lookout drilling is planned in 2020. Producer MT6-06 was fracture stimulated in March 2019. The ongoing development scheme premises water injection with alternating gas injection for pressure maintenance and improved recovery. Gas injection commenced in June 2019. Cumulative water injection in 2019 was 8.1 MMBW. Water production in 2019 was 0.5 MMBW which equates to an annual average water cut of 7%. 2: 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, 2020. The cumulative I/W ratio at the end of 2019 was 0.95. The following is a summary of the Lookout Oil Pool status as of January 1, 2020.

Please see Attachment 3 for the 10-412 report of reservoir pressures. 4: Results and Analysis of Production and Injection Log Surveys, Temperature, Tracer Surveys, Observation Well Surveys and Special Monitoring An IPROF was completed on well MT6-08 on November 3, 2019 while the well was on water injection. Results of the IPROF are as follows: 2019 GMTU Reservoir Surveillance Report 3 A follow-up IPROF was completed on well MT6-08 on December 16, 2019 while the well was on water injection. Results of the IPROF are as follows: 2019 GMTU Reservoir Surveillance Report 4 A production log was run on MT6-03 on December 14, 2019. The purpose of this log was to evaluate zones of water influx. Results of the PPROF are as follows: 5: Review of Production Allocation Factors and Issues Well test and allocation review shows a total of 119 well tests were used to allocate production from the Lookout Oil Pool in 2019. 2019 GMTU Reservoir Surveillance Report 5 Attachment 1: Greater Moose’s Tooth Unit Map 2019 GMTU Reservoir Surveillance Report 6 Attachment 2: Reservoir Pressures at Datum Lookout Oil Pool 2019 GMTU Reservoir Surveillance Report 7 6.
