  (1) Mcf equivalents (Mcfe) consist of natural gas reserves in mcf plus NGLs converted to mcf using a factor of 6 mcf for each barrel of NGL.
Schedule of prices as adjusted for transportation, quality

The following prices as adjusted for transportation, quality, and basis differentials were used in the calculation of the standardized measure:

 

    2015     2014     2013  
                   
Oil per Bbl   $ 43.54     $ 85.63     $ 91.06
