ABSTRACT:
A downhole oil well pump apparatus is useful for lifting oil from the lower end of production tubing adjacent the formation to the earth's surface. The apparatus includes a tool body that can be lowered into the oil well to a level that contains oil that is to be pumped. Packers are used to close off the tubing below the tool body. The tool body includes a bladder that flexes between expanded and contracted positions. The tool body includes a production channel for transmitting oil from the bladder to the earth's surface. Valves above and below the bladder control fluid flow from the bladder to the production channel. The bladder is driven with pressurized gas such as butane.
