By using the formula below, you can arrive at the pressure (PSIA) that an Annugas Production Enhancer® will draw the casing pressure down to.
|Formula:||MCF/D x 1600||= PSIA|
|S X L X A|
MCF/D is the gas production of the well.
|Where||S = Strokes/minute of walking beam|
|L = Length of stroke of Annugas in feet|
|A = Area of Annugas piston in Compression Area (in2)|
|P = Suction pressure absolute (PSIA)|
|And:||Diam. of Piston (in.)||Compression Area (in2)|
S=6, L=4, A=51.5
|12 X 1600||= 15.5 PSIA|
|6 x 4 x 51.5|
Subtract absolute pressure (14) to get guage reading.
