Abstract
A method and systems for using a non-volatile solvent to recover heavy oils are provided. In a method a solvent that includes a non-volatile component is injected into the reservoir. A mobilizing fluid is injected into the reservoir. Fluid is produced from the reservoir, wherein the fluid comprises the solvent, the mobilizing fluid, and the hydrocarbons from the reservoir.
Claims26
A method of recovering hydrocarbons from a reservoir, comprising
- injecting a solvent comprising a non-volatile component into a well in the reservoir;
- injecting a mobilizing fluid into the reservoir;
- and
- producing fluid from the reservoir, wherein the fluid comprises the solvent, the mobilizing fluid, and the hydrocarbons from the reservoir.
1 more element
A system for recovering heavy oil from a reservoir, comprising:
- a reservoir comprising heavy oil;
- an injection well configured to inject at least a mobilizing agent into the reservoir;
- a production well configured to produce at least the heavy oil and the mobilizing agent from the reservoir;
- and
- a tubular placed within the injection well, the production well, or both, wherein the tubular is configured to convey a solvent into a well, and wherein the solvent comprises a non-volatile component.
2 more elements
A method for recovering hydrocarbons from a reservoir after a no-flow condition, comprising:
- injecting a solvent comprising a non-volatile component into the reservoir, wherein the solvent contacts the reservoir;
- soaking the solvent in contact with the reservoir;
- placing the reservoir back in service;
- injecting a mobilizing fluid into the reservoir;
- and
- producing fluid from the reservoir, wherein the fluid comprises the solvent, the mobilizing fluid, and the hydrocarbons from the reservoir.
