A wet gas reservoir has 5 wells. The gas flows from each well through
separate 4-inch flowlines to a common separator for a distance of 0.5 mile.
The gas flows from the common separator to the compressor through a 6-
inch line for a distance of 1 mile. The reciprocating compressor sends the gas
to the point of sale through an 8-inch line for a distance of 3 miles. The
following information is available:
Point of Sale Pressur: 1200 psia
Bottomhole Flowing Pressur: 1200psia
8-inch Line : T = 80°F 6-inch Line : T = 80°F 4-inch Line : T = 80°F
Compressor : E = 0.80
Separator : Yg = 0.60, fg = 0.9
Tubing d = 2.441 inches ft.
TVD = MD = 6000 ft.
Wellbore: T = 90°F
Pp = 14.7 psia To = 60°F
Determine the required compressor horsepower to deliver 40 MMcfd to the
point of sale.
