A method, system, and composition for producing oil from a formation utilizing an oil recovery formulation comprising a surfactant, an ammonia liquid, an alkali metal carbonate or bicarbonate, a polymer, and water are provided.

Method, system, and composition for producing oil

An oil shale formation may be treated using an in situ thermal process. Heat may be applied to the formation to raise a temperature of a portion of the formation to a pyrolysis temperature. Heat input into the formation may be controlled to raise the temperature of portion at a selected rate during pyrolysis of hydrocarbons within the formation. A mixture of hydrocarbons, H, and/or other formation fluids may be produced from the formation.

In situ recovery from a hydrocarbon containing formation

A method including a) injecting into the formation an aqueous solution containing a polymer and a surfactant to create a organic phase and a aqueous phase, the surfactant being capable of reducing the interfacial tension between the phases to less than 1 dyne/cm; b) recovering a portion of the organic and aqueous phases containing at least a portion of the polymer and surfactant components and a portion of native petroleum surfactants generated in the porous formation; c) adjusting the conditions of the recovered portions to force a portion of the polymer and surfactant from one phase into the other phase by use of chemical, physical, electrical or gravitational means or a combination of said means; d) separating the polymer-and surfactant-containing phase; e) concentrating the polymer and surfactant components in the separated phase; and f) re-injecting at least a portion of the concentrated polymer and surfactant components into the formation.

Recovery and recycling of chemicals in chemical flooding process

An oil shale formation may be treated using an in situ thermal process. Heat may be applied to the formation to raise a temperature of a portion of the formation to a pyrolysis temperature. Heat input into the formation may be controlled to raise the temperature of portion at a selected rate during pyrolysis of hydrocarbons within the formation. A mixture of hydrocarbons, H, and/or other formation fluids may be produced from the formation. The mixture may be separated into condensable hydrocarbons and non-condensable hydrocarbons. The condensable hydrocarbons removed from the formation may be a high quality oil that has a relatively low olefin content and a relatively high API gravity.

A oil shale formation may be treated using an in situ thermal process. A mixture of hydrocarbons, H, and/or other formation fluids may be produced from the formation. Heat may be applied to the formation to raise a temperature of a portion of the formation to a pyrolysis temperature. Heat sources may be used to heat the formation. The heat sources may be positioned within the formation in a selected pattern.

In situ thermal processing of an oil shale formation using a pattern of heat sources

An in situ process for treating a diatomite formation is provided. The process may include providing heat from one or more heaters to at least a portion of the formation. The heat may be allowed to transfer from the one or more heaters to a part of the formation such that heat from the one or more heat sources pyrolyzes at least some hydrocarbons within the part. Hydrocarbons may be produced from the formation.

In situ thermal processing of a heavy oil diatomite formation

A method for treating a relatively permeable formation containing heavy hydrocarbons in situ may include providing heat from one or more heat sources to a portion of the formation. The heat may be allowed to transfer from the heat sources to a selected section of the formation. The transferred heat may pyrolyze at least some hydrocarbons within the selected section. A mixture of hydrocarbons may be produced from the selected section. In some embodiments, pressure may be controlled to produce a desired property in the produced mixture.

In situ thermal processing of a relatively permeable formation while controlling pressure

A method for treating a relatively permeable formation containing heavy hydrocarbons in situ may include providing heat from one or more heat sources to a portion of the formation. The heat may be allowed to transfer from the heat sources to a selected section of the formation. The transferred heat may pyrolyze at least some hydrocarbons within the selected section. A mixture of hydrocarbons may be produced from the selected section. In some embodiments, a reducing environment may be maintained in a portion of the formation.

In situ thermal processing of a relatively permeable formation in a reducing environment

An oil shale formation may be treated using an in situ thermal process. A mixture of hydrocarbons, H, and/or other formation fluids may be produced from the formation. Heat may be applied to the formation to raise a temperature of a portion of the formation to a desired temperature. A heating rate for a selected volume of the formation may be controlled by altering an amount of heating energy per day that is provided to the selected volume.

In situ thermal processing of an oil shale formation using a controlled heating rate

An oil shale formation may be treated using an in situ thermal process. A mixture of hydrocarbons, H, and/or other formation fluids may be produced from the formation. Heat may be applied to the formation to raise a temperature of a portion of the formation to a pyrolysis temperature. Heat may also be applied to the formation to increase a permeability of the formation. In some embodiments, the permeability of a portion of the formation may increase to a relatively high permeability as compared to the initial permeability.
