Note 12: Subsequent events

On October 13, 2017, we entered into a purchase and sale agreement with Perdure Petroleum, LLC., for the sale of our EOR assets along with some minor assets within geographic proximity for total cash consideration, subject to normal and customary closing adjustments, of $170,000 plus certain contingent payments. An $11,900 performance deposit was received in October 2017 and will be applied towards the purchase price at closing, which we expect to occur in November 2017. The effective date of the purchase is June 1, 2017.
