Unproved property costs of $132.6 million and $117.6 million have been excluded from amortization as of September 30, 2018 and December 31, 2017, respectively. An additional $18.7 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 September 30, 2018. We transferred $11.4 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 nine months ended September 30, 2018. We capitalized internal costs of $2.4 million and $1.6 million and interest of $7.1 million and $0.1 million during the nine months ended September 30, 2018 and 2017, respectively, in accordance with our accounting policies. Average depreciation, depletion and amortization (“DD&A”) per barrel of oil equivalent of proved oil and gas properties was $15.83 and $11.93 for the nine months ended September 30, 2018 and 2017, respectively.
