| titleOfInvention | System and method of improved fluid production from artificial lift gaseous wells using pressure cycling |
| abstract | A system and method are provided for improving hydrocarbon production from gaseous wells, and in particular improving hydrocarbon production using pumping systems employing artificial lifts. The pumping system of the well is controlled so as to cyclically decrease and increase gas pressure in the casing annulus, thus cyclically decreasing PBHP in response to the decrease in the casing annulus pressure and permitting the PBHP to increase in response to the increase in casing annulus pressure. Production of fluid from the reservoir is therefore increased during the cyclical decrease in casing annulus pressure, and production of fluid from the downhole pump is increased during the cyclical increase in casing annulus pressure. In addition, gas interference due to production of foam in the casing surrounding a downhole pump can be mitigated by forcing liquid from the foam during the period of increased casing annulus pressure. |
