The Company recognized $3.5 million in revenues during the first six months of 2015 compared to $7.5 million during the first six months of 2014.

Michael J. Rugen, CEO said, “The Company continues to deal with depressed crude oil pricing. Like others in this industry, our drilling plans are largely on hold until prices improve.  We continue to consider workover and recompletion decisions on our existing wells as they arise in the context of current market realities.  However, we have seen some downward movement in service costs and intend to take advantage of those cost reductions by initiating a seismic program on our recently leased acreage in Kansas.  During the second quarter of 2015, we continued to evaluate corporate opportunities, as well as opportunities to purchase acreage and producing properties.  We believe we have started to see the beginning of distressed sales by others of producing properties and expect more of these acquisition opportunities to appear as existing price hedging begins to fall off and other producers are forced to deal directly with the realities of the current market.  We intend to evaluate taking advantage of those opportunities either on our own or in joint ventures with industry partners.”
