Given the following data for a gas well in a field with an area of 120 acres, formation thickness of 300 ft, porosity of 34%, and gas saturation of 0.82:
COMP Mass Fraction, %
CO2 4.60
H2S 6.50
C1 76.8
C2 4.60
C3 4.30
C7+ 3.20
For heptane plus, specific gravity is 0.78 and molecular weight is 175 lb/lb mole and the gas mixture is at 1900 psig and 175 degree F.
Determine:
1. Gas density and gas specific gravity
2. Gas weight in lb mass and lb moles
3. Gas volume in SCF
