Sizing Formula
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) |
| 5 | 34.4 | |
| 6 | 51.5 | |
| 7 | 72.1 | |
| 8 | 95.5 | |
| 10 | 152.0 | |
| Example | (Model AG648) S=6, L=4, A=51.5 12MCF/D |
|
| 12 X 1600 | = 15.5 PSIA | |
| 6 x 4 x 51.5 |
Subtract absolute pressure (14) to get gauge reading.
