System and methods for removing fluids from a subterranean well
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, an apparatus for removing a first fluid within the distal section of the inner tubing string, and an apparatus for removing a second fluid within the proximal section of the inner tubing string.
1. A method of removing fluids from a subterranean well, comprising:
inserting at least one inner tubing string through a well, wherein an outer tubing string surrounds the inner tubing string forming a first annulus therebetween and a well casing surrounds the outer tubing string forming a second annulus therebetween, the well having a distal section 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;
injecting a first fluid into the first annulus at a proximal end of the well;
rerouting the first fluid from the first annulus proximate the proximal well section into the inner tubing string using a crossover device;
transporting a second fluid from the fluid source to the proximal well section using a first fluid removal means;
rerouting the second fluid from the first annulus proximate the distal section into the inner tubing string using the crossover device;
transporting the second fluid from the proximal well section to the proximal end of the well using a second fluid removal means; and
transporting a third fluid from the fluid source to the proximal end of the well through the second annulus.
2. The method of claim 1 , wherein the first fluid comprises an injected gas, the second fluid comprises an unwanted liquid, and the third fluid comprises a desired fluid.
3. The method of claim 1 , wherein the first fluid comprises an injected gas, the second fluid comprises a desired fluid, and the third fluid comprises an unwanted liquid.
