The following table summarizes our property and equipment as of the dates presented:
Unproved property costs of $63.5 million and $49.9 million have been excluded from amortization as of March 31, 2021 and December 31, 2020, respectively. An additional $0.5 million and $1.2 million of costs, associated with wells in-progress for which we had not previously recognized any proved undeveloped reserves, were excluded from amortization as of March 31, 2021 and December 31, 2020, respectively. We transferred $7.6 million and $1.4 million of undeveloped leasehold costs associated with acreage unlikely to be drilled or associated with proved undeveloped reserves, including capitalized interest, from unproved properties to the full cost pool during the three months ended March 31, 2021 and 2020, respectively. We capitalized internal costs of $0.7 million and $0.8 million and interest of $0.8 million and $0.7 million during the three months ended March 31, 2021 and 2020, respectively, in accordance with our accounting policies. Average depreciation, depletion and amortization per barrel of oil equivalent of proved oil and gas properties was $12.92 and $16.73 for the three months ended March 31, 2021 and 2020, respectively.
At the end of each quarterly reporting period, the unamortized cost of our oil and gas properties, net of deferred income taxes, is limited to the sum of the estimated after-tax discounted future net revenues from proved properties adjusted for costs excluded from amortization (the “Ceiling Test”). As of March 31, 2021, the carrying value of our proved oil and gas properties exceeded the limit determined by the Ceiling Test, resulting in a $1.8 million impairment for the quarter.
