The computation of gas properties includes corrections for contaminants
and adjustments for condensate content. ResGAS also calculates wet gas in
place and recoverable wet-, dry- and sales-gas volumes as well as recoverable
condensate volumes.
ResGAS computes the estimated recovery of propane, butane and sulfur and
approximates the BTU content of separator and gas sales. A user must enter
separator-gas component percentages derived from laboratory analysis and
other data input, including well and reservoir parameters and recovery factors.
