8.  OIL AND NATURAL GAS PROPERTIES AND EQUIPMENT

We review our oil and natural gas producing properties for impairment quarterly or whenever events or changes in circumstances indicate that the carrying amount of such properties may not be recoverable. When an oil and natural gas property’s undiscounted estimated future net cash flows are not sufficient to recover its carrying amount, an impairment charge is recorded to reduce the carrying amount of the asset to its fair value. The fair value of the asset is measured using a discounted cash flow model relying primarily on Level 3 inputs into the undiscounted future net cash flows. The undiscounted estimated future net cash flows used in our impairment evaluations at each quarter end are based upon the most recently prepared independent reserve engineers’ report adjusted to use forecasted prices from the forward strip price curves near each quarter end and adjusted as necessary for drilling and production results.

There was no triggering event in the second quarter of 2018 that would cause us to believe the value of oil and natural gas producing properties should be impaired.  Factors considered included the fact that we incurred no significant capital expenditures in 2018 related to the fields in the Etame Marin block, the future strip prices for the second quarter of 2018 modestly increased from the first quarter of 2018, and there were no indicators that adjustments were needed to the  year-end reserve report.

There was no triggering event in the second quarter of 2017 that caused us to believe the value of oil and natural gas producing properties should be impaired.  During the second quarter of 2017, prices remained stable and we incurred no significant capital spending.  We considered these and other factors and determined that there were no events or circumstances triggering an impairment evaluation for all of our fields.
