Abstract
There is disclosed a pump and pumping system for pumping dense phase gases, specifically for injecting carbon dioxide into an oil or gas reservoir that includes a pump, a motor, and a casing in which the pump and motor reside. There is also disclosed a pump and pumping system for injecting dense phase greenhouse gases into a reservoir or underwater. The pump may include a downhole electric submersible pump. A method of controlling the pump and pumping system is also described involving the use of a variable speed drive in conjunction with an on-line gas chromatograph to maintain a constant carbon dioxide injection rate.
