Abstract
The present invention comprises a downhole unit that includes at least one plunger and that uses a power fluid to recover production fluid from a well. The downhole unit recovers production fluid and brings it to the surface of the well during both the downward and upward motion of the at least one plunger. The downhole unit can also optionally dispose of unwanted fluids in a formation.
Claims7
A method for removing fluid from a well comprising:
- disposing a downhole unit at least partially within the well, the downhole unit comprising a first side and a second side, the first side comprising one or more plungers disposed on a first pipe, and the second side comprising a second pipe;
- connecting a pulsar to the first and second pipes;
- forcing the one or more plungers of the downhole unit in a downward direction and forcing the production fluid into the second pipe and up to the pulsar;
- forcing the one or more plungers of the downhole unit in an upward direction and forcing production fluid into the first pipe and up to the pulsar;
- commingling power and production fluids in the pulsar;
- and
- releasing the fluids through at least one valve disposed on the pulsar.

A system for removing fluid from a well comprising:
- a pulsar that allows commingling of power and production fluids;
- a downhole unit comprising a first side and a second side, said first side comprising one or more plungers disposed on a first pipe, and said second side comprising a second pipe at least partially within the well;
- said pulsar connected to said first and second pipes;
- wherein said one or more plungers are forced in a downward direction thereby forcing production fluid into said second pipe and up to said pulsar;
- said one or more plungers forced in an upward direction thereby forcing production fluid into said first pipe and up to said pulsar;
- and
- at least one valve disposed on said pulsar for releasing commingled production and power fluids.
