Abstract
Systems and methods are provided for lifting hydrocarbons from reservoirs. A method includes injecting a heat carrier fluid comprising steam, hot water, or both into a first well and injecting an organic compound into a second well. The organic compound is selected to vaporize to a gas from the heat provided by the heat carrier fluid, forcing produced fluids to the surface. The produced fluids are collected at the surface.
Claims24
A method for lifting fluids from a reservoir, comprising:
- injecting a heat carrier fluid comprising steam, hot water, or both into a first well;
- injecting an organic compound into a second well, wherein the organic compound is selected to vaporize to a gas from the heat provided by the heat carrier fluid, forcing produced fluids to the surface through the second well;
- and
- collecting the produced fluids at the surface.
1 more element
A system for harvesting resources in a reservoir, comprising:
- a production well comprising a horizontal section located substantially proximate to a base of the reservoir;
- an injection system configured to inject an organic compound into an tube in the production well, wherein the organic compound is selected so as to vaporize at the end of the tube;
- and
- a continuous production system configured to produce a fluid from the production well, wherein the fluid comprises a bitumen and the organic compound.
1 more element
A method for harvesting hydrocarbons from a reservoir, comprising:
- drilling a production well substantially proximate to a base of a reservoir;
- injecting steam into the reservoir to lower a viscosity of bitumen, wherein the bitumen flows into the production well;
- injecting an organic compound in the liquid phase into the production well, wherein the organic compound flashes into a vapour in the production well;
- and
- producing fluids from the production well, wherein the fluids comprise the vapour and the bitumen.
