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
