Schedule of Product Prices Used for Valuing the Reserves

The weighted-average benchmark product prices used for valuing the reserves are based upon the average of the first-day-of-the-month price for each month within the period January through December of each year presented:

	2022		2021
Oil ($/Bbl):
WTI (1)	$	93.67	$	66.56
NGL ($/Bbl):
WTI (1)	$	93.67	$	66.56
Natural Gas ($/MMbtu):
Henry Hub (2)	$	6.36	$	3.60

(1) The weighted average WTI price was adjusted by lease for quality, transportation fees, and a regional price differential.

(2) The weighted average Henry Hub price was adjusted by lease for energy content, compression charges, transportation fees, and regional price differentials.
