1    Excludes the corporate office building and related other assets acquired in connection with the Lonestar Acquisition that were classified as Assets held for sale on the consolidated balance sheets as of December 31, 2021. We closed on the sale of the corporate office building in July 2022. See Note 4 for additional information. As of December 31, 2022, we had $1.2 million remaining other assets classified as Assets held for sale excluded from above.
Unproved property costs of $41.9 million and $57.9 million have been excluded from amortization as of December 31, 2022 and December 31, 2021, respectively. The total costs not subject to amortization as of December 31, 2022 were incurred in the following periods: $0.9 million in 2022, $1.3 million in 2021, $0.7 million in 2020 and $33.2 million prior to 2019 as well as $5.8 million of capitalized interest applied thereto. We transferred $25.2 million and $17.8 million of unproved leasehold costs, including capitalized interest, associated with proved undeveloped reserves, and acreage unlikely to be drilled or expiring acreage, to the full cost pool during the years ended December 31, 2022 and 2021, respectively. We capitalized internal costs of $5.3 million, $4.1 million and $2.1 million and interest of $4.3 million, $3.6 million and $2.7 million during the years ended December 31, 2022, 2021 and 2020, respectively, in accordance with our accounting policies. Average DD&A per boe of proved oil and gas properties was $16.42, $12.96 and $15.83 for the years ended December 31, 2022, 2021 and 2020, respectively.
Ceiling Test
Beginning in early 2020, certain events such as the COVID-19 pandemic coupled with decisions by the Organization of the Petroleum Exporting Countries (“OPEC”) and Russia (together with OPEC, collectively “OPEC+”) negatively impacted the oil and gas industry with significant declines in crude oil prices and oversupply of crude oil. Then in early 2021 with the deployment of vaccines and resulting increased mobility and global economic activity and other factors, demand for oil increased and commodity prices began to recover. Prior to the announced significant production cut to take effect in November 2022, OPEC+ had previously employed a strategy to gradually increase production. These shifts in OPEC+ production levels as well as the Russia-Ukraine war and related sanctions, which began in the first quarter of 2022, continue to contribute to a high level of uncertainty surrounding energy supply and demand resulting in volatile commodity prices. WTI crude oil and natural gas prices surged with prices over $120 per bbl and over $9 per Mcf, respectively, during the first half of 2022 due to oil supply shortage concerns. During the second half of 2022, WTI crude oil and natural gas prices dropped to lows under $72 per bbl and $4 per Mcf, respectively.
As discussed in Note 3, the Ceiling Test utilizes commodity prices based on a trailing 12-month average based on the closing prices on the first day of each month. With the higher commodity prices in 2022, we did not record any impairments of our oil and gas properties during the year ended December 31, 2022. However, the years ended December 31, 2021 and 2020 were impacted by the decline in commodity prices as a result of the various factors discussed above, resulting in impairments of our oil and gas properties of $1.8 million and $391.8 million, respectively.
