The following table summarizes our property and equipment as of the dates presented:



	September 30,			December 31,
	2017			2016
Oil and gas properties:
Proved	$	369,384		$	251,083
Unproved	147,594			4,719
Total oil and gas properties	516,978			255,802
Other property and equipment	12,484			3,575
Total properties and equipment	529,462			259,377
Accumulated depreciation, depletion and amortization	(43,402		)	(11,904		)
	$	486,060		$	247,473

Unproved property costs of $147.6 million and $4.7 million have been excluded from amortization as of September 30, 2017 and December 31, 2016, respectively. We transferred $1.9 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, 2017. We capitalized internal costs of $1.6 million and interest of $0.1 million during the nine months ended September 30, 2017 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 $11.93 for the nine months ended September 30, 2017, $10.04 for the Predecessor period from January 1, 2016 through September 12, 2016 and $11.09 for the Successor period from September 13, 2016 through September 30, 2016. The DD&A rate for the Predecessor period was determined under the successful efforts method while the Successor periods subsequent to September 12, 2016 were determined under the full cost method (see Note 2).
