Abstract
A system for producing oil and/or gas from an underground formation comprising a first array of wells dispersed above the formation; a second array of wells dispersed above the formation; wherein the first array of wells comprises a mechanism to inject a miscible enhanced oil recovery formulation into the formation while the second array of wells comprises a mechanism to produce oil and/or gas from the formation for a first time period; and wherein the second array of wells comprises a mechanism to inject a miscible enhanced oil recovery formulation into the formation while the first array of wells comprises a mechanism to produce oil and/or gas from the formation for a second time period.
Claims16
A system for producing oil or gas from an underground formation comprising:
- a first array of wells dispersed above the formation;
- a second array of wells dispersed above the formation;
- a miscible solvent comprising a carbon disulfide formulation;
- wherein the first array of wells comprises a pump to inject the miscible solvent into the formation while the second array of wells comprises a pump to produce oil or gas from the formation for a first time period;
- and
- wherein the second array of wells comprises a pump to inject the miscible solvent into the formation while the first array of wells comprises a pump to produce oil or gas from the formation for a second time period.
A method for producing oil or gas comprising:
- injecting a miscible solvent comprising a carbon disulfide formulation into a formation for a first time period from a first well;
- producing oil or gas from the formation from a second well for the first time period;
- injecting the miscible solvent into the formation for a second time period from the second well;
- and
- producing oil or gas from the formation from the first well for the second time period.
