초록 ▼

A method of treating an oil shale formation in situ includes providing heat directly from one or more heaters to at least a portion of the formation. The heat is controlled to maintain an average temperature of the portion below a dissociation temperature of carbonate minerals in the portion. A first fluid is injected into the portion of the formation. A second fluid is produced from the formation. An in situ conversion process is conducted in the portion of the formation.

What is claimed is: 1. A method of treating an oil shale formation in situ, comprising: providing heat directly from one or more heaters to at least a portion of the formation; controlling the heat to maintain an average temperature of the portion below a dissociation temperature of carbonate minerals in the portion; injecting a first fluid into the portion of the formation; producing a second fluid from the formation; and conducting an in situ conversion process in the portion of the formation. 2. The method of claim 1, wherein the portion of the formation comprises nahcolite. 3. The method of claim 1, wherein the second fluid comprises at least some carbonate minerals dissolved in the first fluid. 4. The method of claim 1, further comprising removing mass from the portion of the formation in the second fluid. 5. The method of claim 1, further comprising removing mass from the portion of the formation in the second fluid such that a permeability of the portion of the formation increases. 6. The method of claim 1, further comprising removing mass from the portion of the formation in the second fluid and decreasing a heat transfer time in the portion of the formation. 7.

The method of claim 10, further comprising controlling the heat such that the average temperature of the portion is less than about 100° C. 16. The method of claim 10, further comprising conducting the in situ conversion process after at least some of the second fluid has been produced from the formation. 17. The method of claim 10, wherein the in situ conversion process comprises producing at least some pyrolyzed fluids from the portion of the formation. 18. A method of treating an oil shale formation in situ, comprising: providing heat directly from one or more heaters to at least a portion of the formation, wherein the portion of the formation comprises carbonate minerals; controlling the heat to maintain an average temperature of the portion below a about 100° C. in the portion; injecting a first fluid into the portion of the formation; producing a second fluid from the formation; and conducting an in situ conversion process in the portion of the formation. 19. The method of claim 18, further comprising removing mass from the portion of the formation in the second fluid such that a permeability of the portion of the formation increases. 20.
