Unproved property costs of $4.1 million and $4.7 million have been excluded from amortization as of June 30, 2017 and December 31, 2016, respectively. We transferred $2.0 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 six months ended June 30, 2017. We capitalized internal costs of $1.1 million and interest of $0.1 million during the six months ended June 30, 2017 in accordance with our accounting policies. Average depreciation, depletion and amortization per barrel of oil equivalent of proved oil and gas properties was $11.74 and $10.02 for the six months ended June 30, 2017 and 2016, respectively.
