International Classification:

E21B 43/24

US Classification:

1662722

Abstract:

A method for containing and capturing liquids and gases generated during in situ pyrolysis that migrate through pyrolysis generated or natural fractures includes placing a row of horizontal hydraulic fractures above and below the heated zone and completing production wells within the horizontal hydraulic fractures. The method serves at least two purposes: 1) provides a local zone of weak mechanical strength to blunt the propagation of vertical pyrolysis generated fractures and 2) provides a drainage point for fluids to relieve pressure in the formation and improve recovery. Preferably, the organic-rich rock formation is an oil shale formation.

US Classification:

175 40, 16625012, 166248

Abstract:

Systems and methods of detecting an intersection between a wellbore and a subterranean structure that includes a marker material. The systems and methods include drilling the wellbore and determining that the wellbore has intersected a portion of the subterranean structure that includes the marker material by detecting the marker material. The systems and methods also may include distributing the marker material within the subterranean structure, aligning the marker material within the subterranean structure, determining one or more characteristics of the marker material, ceasing the drilling, repeating the method, and/or producing a hydrocarbon from the subterranean structure. The systems and methods further may include forming an electrical connection between an electric current source and a granular resistive heater that forms a portion of the subterranean structure, forming the granular resistive heater, and/or forming the subterranean structure.

Abstract:

The present disclosure provides a system and method for recovering hydrocarbons that minimize surface disturbance. The system includes an electrical heater, electrical cables substantially within the subsurface formation that connect to the electrical heater, electrical pathways substantially within the subsurface formation that are configured to transmit power to the electrical heater, and a first local electrical room that is configured to (i) detect a pathway error within the electrical pathways based on pathway characteristics of pathway sensors and (ii) correct the pathway error by switching power transmitted from a first one of the electrical pathways to a second one of the electrical pathways that is separate from the first one of the electrical pathways.

Abstract:

Systems and methods for bulk heating of a subsurface formation with at least a pair of electrode assemblies in the subsurface formation are disclosed. The method may include electrically powering the pair of electrode assemblies to resistively heat a subsurface region between the pair of electrode assemblies with electrical current flowing through the subsurface region between the pair of electrode assemblies; flowing a shunt mitigator into at least one of the pair of electrode assemblies; and mitigating a subsurface shunt between the pair of electrode assemblies with the shunt mitigator. Mitigating may be responsive to a shunt indicator that indicates a presence of the subsurface shunt.

These methods may include determining an expected operating range for an environmental parameter for the composite granular resistive heating material within a subterranean formation, selecting a first material, selecting a second material, and/or generating the composite granular resistive heating material from the first material and the second material. The methods may include forming a granular resistive heater. The methods may include determining the expected operating range and/or locating the composite granular resistive heating material within the subterranean formation. The systems may include a composite granular resistive heating material that includes a first material and a second material and that defines a composite functional relationship between an electrical property of the composite granular resistive heating material and the environmental parameter. The composite functional relationship includes a mathematical extremum.
