Methods and apparatus for removing liquid from a gas producing well
A method and apparatus for pumping fluid at a wellhead that improves liquid removal by eliminating the need to transport liquid produced from a well to containment facilities using trucks or large diameter pipelines capable of accommodating periodic surges of a high volume of fluid. The danger that the liquid will freeze in cold weather is also addressed. The invention removes liquid from the well site through a small diameter pipeline as a continuous flow at a constant flow rate.
1. An apparatus for withdrawing gas from a well comprising:
(a) a pumping assembly for drawing fluid from the well;
(b) a holding tank located within a cavity defined by a support structure for supporting the pump assembly and having an inflow port directly connected to the pumping assembly and an outflow port directly connected to a pipeline to remove the gas from a well site at which the apparatus is provided;
(c) an air compressor for pressuring gas in the holding tank located within the cavity defined by the support structure, the pressurized gas entering to the pipeline; and
(d) a power source that powers the pumping assembly and the air compressor.
2. An apparatus for withdrawing gas from a well comprising:
(a) a pumping assembly for drawing fluid from the well;
(b) a holding tank located within a cavity defined by a support structure for supporting the pumping assembly and having an inflow and an outflow port for directing gas in and out of the holding tank, wherein the inflow port is directly connected to the pumping assembly, and the outflow port is directly connected to a pipeline to remove the gas from a well site at which the apparatus is provided;
(c) a holding tank pump connected to the holding tank and located within the cavity defined by the support structure;
(d) a vapor recovery unit located within the cavity defined by the support structure; and
(e) a power source that power the pumping assembly, the holding tank pump and the vapor recovery unit.
