More than 30% of U.S. production today comes from enhanced oil recovery techniques.
620,000 marginal wells
350,000 idle wells
The solution of the DOE towards this problem is to decrease the costs of production by developing new technologies.

This device is designed to reduce GAS LOCKING.
This tool is optional for this system.
The Dump/Vent Valve fits in the base of the pump barrel between the ball and seat and the hold down. The valve is opened by lifting the plunger against the top of the pump barrel.
This valve allows for controlled ventingor dumping the fluid out of the tubing.
It could be used to spot chemicals at the bottom of the hole and to wash out scale or other matter from around the pump barrel to reduce chances of sticking the pump.
We think this system could be used to spot hot fluids down the tubing to melt paraffin. In wells where packers are run, this could be a helpful tool to move the fluid from tubing to formation for any reason. This valve is closed by hydrostatic pressure as the plunger is lowered back into the pump barrel.
This valve can be run on any reciprocating pump and is optional for this system.
