﻿ During the years ended December 31, 2017, 2016, and 2015, the Company recorded depletion expense of $796,000, $1.0 million, and $2.5 million, respectively. In addition, as a result of the ceiling test impairments during 2015 and the first three quarters of 2016, the accumulated depreciation, depletion, and amortization was been netted against the cost to reflect the post impairment value of the oil and gas properties. As no ceiling test impairment was recorded during the quarter ended December 31, 2016, nor during any of the quarters ended in 2017, these amounts were not netted against cost, but remained in accumulated depreciation, depletion, and amortization at December 31, 2017 and December 31, 2016.
