+Added: The decrease was primarily due to a 35% reduction in the SEC-prescribed oil price at year-end 2020 as compared to 2019 and a decrease in development activity.
+Added: As a result of lower demand caused by the COVID-19 pandemic and the oversupply of crude oil, spot and future prices of crude oil fell to historic lows during the second quarter of 2020, which in turn reduced development activity in the Williston Basin.
+Added: The decrease in development activity in 2020 led to a 56% reduction in our developmental capital expenditures compared to 2019 as well as a decrease in the number of undeveloped drilling locations reflected in our 2020 proved reserve estimates.
+Added: The number of proved undeveloped wells included in the reserves was reduced from 107.5 net wells in 2019 to 58.8 net wells in 2020.

Our future development drilling program includes the drilling of approximately 58.8 proven undeveloped net wells before the end of 2025 at an estimated cost of $341.0 million.
−Removed: Our development plan for drilling proved undeveloped wells calls for the drilling of 44.0 net wells during 2020 (includes 16.9 net wells drilled at December 31, 2019, but classified as proved undeveloped due to Cawley’s internal guidelines which require greater than 50% of total costs to be incurred to be classified as developed), 18.2 net wells during 2021, 13.0 net wells during 2022, 15.1 net wells during 2023 and 17.2 net wells during 2024 for a total of 107.5 net wells.

+Added: Our proved undeveloped locations were reduced from 107.5 net wells at December 31, 2019 to 58.8 net wells at December 31, 2020 due to lower commodity prices and reduced development activity.
We expect that our proved undeveloped reserves will continue to be converted to proved developed producing reserves as additional wells are drilled including our acreage.

Additionally, our proved undeveloped reserves at December 31, 2020 included 8.2 MMBoe for net wells that had commenced drilling activities but remained classified as undeveloped reserves due to Cawley’s internal guidelines which require greater than 50% of the total costs to have been incurred in order to be classified as proved developed (the related development costs incurred at December 31, 2020 were $20.5 million).
−Removed: In 2019, we also added 12.3 MMBoe of proved undeveloped reserves primarily in our North Dakota areas of operations as a result of higher commodity prices and increased well performance and development activity in the Williston Basin.
+Added: In 2020, we also added 5.6 MMBoe of proved undeveloped reserves as a result of our acquisition and development activity.
The SEC-prescribed commodity prices (after adjustment for transportation, quality and basis differentials) were $17.84 lower per barrel of oil and $0.51 lower per Mcf of natural gas at year-end 2020 as compared to year-end 2019.
−Removed: Additionally, we had negative revisions of 2.3 MMBoe due to lower pricing, partially offset by positive performance revisions due to improved well performance.

We have chosen to compare our proved reserves from the 2020 SEC case to two alternate pricing cases.
−Removed: The first case scenario uses a flat pricing deck of $50.00 per Bbl for oil and $2.50 per MMbtu for natural gas (the “$50 Flat Case”).
−Removed: The second case scenario uses a flat pricing deck of $60.00 per Bbl for oil and $2.50 per MMbtu for natural gas (the “$60 Flat Case”).
+Added: The first alternate scenario uses a flat pricing deck of $50.00 per Bbl for oil and $2.50 per MMbtu for natural gas (the “$50 Flat Case”).
+Added: The second alternate scenario uses a flat pricing deck of $60.00 per Bbl for oil and $2.50 per MMbtu for natural gas (the “$60 Flat Case”).
The sensitivity scenarios were not audited by a third party.
−Removed: In these sensitivity scenarios, all factors other than the commodity price assumptions have been held constant with the SEC case, including the number of proved undeveloped locations, drill schedules and operating costs assumptions.
+Added: In these sensitivity scenarios, all operating cost assumptions and other factors, other than the commodity price assumptions, have been held constant with the SEC case.
+Added: However, the higher pricing in the sensitivity scenarios did result in additional future drilling locations that became economic under the $50 Flat Case and the $60 Flat Case, while they were not economic under the 2020 SEC case.
+Added: As a result, the $50 Flat Case and the $60 Flat Case included an additional 24.4 and 44.6 proved undeveloped net wells, respectively, compared to the 58.8 proved undeveloped net wells included in the 2020 SEC case.
These sensitivities are only meant to demonstrate the impact that changing commodity prices may have on estimated proved reserves and PV-10 and there is no assurance these outcomes will be realized.
