ABSTRACT:
Double acting, gas operated pumps for lifting formation fluids from a well are disclosed as comprising a housing connectible to the lower end of a production string suspended within a well, and a pump assembly which may be lowered into and raised from a landed position within the housing. Upper and lower pump chambers are formed in the pump assembly and a piston is reciprocable in each chamber in response to the alternate supply and exhaust of a pressurized gas to one side thereto for alternately admitting formation fluid to the other side of one piston while pumping it from the other. The spool of a reversing valve for controlling the flow of gas to and from the chambers is connected to one of the pistons in such a manner that it is shifted into its alternate positions with a snap action.
