Abstract
The invention includes systems and methods for removing fluids from a subterranean well. An example embodiment includes a system having a well casing surrounding at least one inner tubing string, where the inner tubing string has a distal section and a proximal section, a first fluid removal means within the distal section of the inner tubing string, and a second fluid removal means within the proximal section of the inner tubing string.
Claims56
A system for removing fluids from a subterranean well having at least one inner tubing string, where the inner tubing string has a distal section and a proximal section, the system comprising;
- a first fluid removal means within the distal section of the inner tubing string;
- and
- a second fluid removal means within the proximal section of the inner tubing string.

A method of removing fluids from a subterranean well, comprising:
- inserting at least one inner tubing string through a well optionally having one or more well casings, the well having a distal portion that extends into a fluid source within a rock formation, wherein the well comprises a proximal well section extending from a surface of the rock formation and a deviated well section extending from the proximal well section to the fluid source;
- transporting at least one unwanted liquid through the inner tubing string from the fluid source to the proximal well section using a first fluid removal means;
- transporting the at least one unwanted liquid through the inner tubing string from the proximal well section to a proximal end of the inner tubing string using a second fluid removal means;
- and
- transporting a desired fluid from the fluid source to the proximal end of the well through an annulus between the inner tubing string and the well casing.

A combined sequential lift system for removing water from a well bore having a first substantially vertical section, comprising
- an inner tube disposed in the well bore;
- a primary pump system disposed in the first substantially vertical section capable of lifting water to a wellhead;
- a secondary pump system capable of removing water from the well bore hole into the inner tube;
- and
- a system sequencer that sequentially controls, adjusts and/or optimizes the operation of the primary and the secondary pump system.
