Downhole electrical submersible power generator
First Claim
1. A downhole submersible electrical power generator, comprising:
- a housing forming a fluid conduit;
an inlet disposed on the housing;
an outlet disposed on the housing, wherein the inlet and the outlet are adapted to allow a fluid to flow into and out of the housing, respectively;
a fluid flow powered electrical power generator disposed inside the housing and adapted to generate electrical power from the fluid flowing through the housing;
a first isolation packer disposed outside the housing between the inlet and the outlet, wherein the first isolation packer is adapted to isolate the inlet and the outlet in different zones in a wellbore; and
a second isolation packer disposed outside the housing, wherein the second isolation packer is adapted to isolate the outlet from a portion of the well,wherein the inlet is disposed in a first zone, wherein the outlet is disposed in a second zone, and wherein the first zone is at a greater depth than the second zone.

Abstract
A method and apparatus is described for a downhole submersible electrical power generator. The electrical power generator includes a housing forming a fluid conduit. An inlet is disposed on the housing. Also, an outlet is disposed on the housing where the inlet and the outlet are adapted to allow a fluid to flow into and out of the housing, respectively. A fluid flow powered electrical power generator is disposed inside the housing and is adapted to generate electrical power from the fluid flowing through the housing. An isolation packer is disposed outside the housing between the inlet and the outlet where the isolation packer is adapted to isolate the inlet and the outlet in different zones in a wellbore.

15. A method for generating electrical power using a downhole submersible electrical power generator, comprising:
-
disposing the downhole submersible electrical power generator in a borehole; isolating a first wellbore zone from a second wellbore zone using an isolation packer disposed outside the downhole submersible electrical power generator, wherein the first wellbore zone is at a higher hydraulic pressure than the second wellbore zone, wherein the first wellbore zone comprises a first perforation and the second wellbore zone comprises a second perforation; flowing a fluid from the first wellbore zone to the second wellbore zone through a fluid path included in the downhole submersible electrical power generator; and generating electrical power dependent on the flowing, wherein the first wellbore zone is at a greater depth than the second wellbore zone. - View Dependent Claims (16, 17, 18, 19, 20, 21)
