Abstract
A technique facilitates a water flood, e.g. dump flood, operation. A standard electric submersible pumping system is deployed in a wellbore to draw water from an aquifer or water source zone along the wellbore. A shroud and a crossover port are used in combination with the submersible pumping system to redirect pumped water downwardly along an isolated flow path. The downward flow of pumped water is directed along the wellbore and injected into a desired, injection zone to facilitate recovery of oil or to perform other types of water flood operations.
Claims22
A method of injecting water into a well zone, comprising:
- deploying a shroud around a non-inverted electric submersible pumping system to create a first flow path and a second flow path in a wellbore;
- drawing water from a water source zone along the first flow path via the electric submersible pumping system;
- pumping the water along the second flow path;
- and
- using a crossover port to direct the flow of water to an injection zone.
A method, comprising:
- using a non-inverted electric submersible pumping system in a wellbore to draw water from a water source zone;
- employing a shroud and a crossover port to redirect a flow of the water downwardly along an isolated flow path;
- and
- injecting the flow into an injection zone.
A system, comprising:
- an electric submersible pumping system positioned in a wellbore in a non-inverted orientation;
- a shroud positioned around the electric submersible pumping system;
- a crossover port engaged with the shroud;
- and
- a flow tube extending downwardly from the crossover port, wherein the shroud, the crossover port and the flow tube cooperate to create a first isolated flow path, along which water can be drawn from a water source zone, and a second isolated flow path, along which the water is redirected downwardly to an injection zone below the electric submersible pumping system.
