摘要： Casing expansion and formation compression for permeability plane orientation. A method of forming at least one increased permeability plane in a subterranean formation includes the steps of: installing a casing section in a wellbore intersecting the formation; expanding the casing section in the wellbore; and then injecting a fluid into the formation, the injecting step being performed after the expanding step is completed. Another method includes the steps of: applying an increased compressive stress to the formation, the compressive stress being radially directed relative to a wellbore intersecting the formation; and then piercing the formation radially outward from the wellbore, thereby initiating the increased permeability plane. Yet another method includes the steps of: applying a reduced stress to the formation, the reduced stress being directed orthogonal to a wellbore intersecting the formation; and then piercing the formation with at least one penetration extending radially outward from the wellbore, thereby relieving the reduced stress at the penetration.

A well system includes at least one generally planar inclusion extending outward from a wellbore into a formation; a fluid injected into the inclusion, hydrocarbons being heated as a result of the injected fluid; and a tubular string through which the hydrocarbons are produced, the tubular string extending to a location in the wellbore below the inclusion, and the hydrocarbons being received into the tubular string at that location.

摘要： A method and apparatus for initiating and propagating a vertical hydraulic fracture in unconsolidated and weakly cemented sediments from a single bore hole to control the fracture initiation plane and propagation of the hydraulic fracture, enabling greater yield and recovery of petroleum fluids from the formation. An injection casing with multiple fracture initiation sections is inserted and grouted into a bore hole. A fracture fluid carrying a proppant is injected into the injection casing and opens the fracture initiation sections to dilate the formation in a direction orthogonal to the required fracture azimuth plane. Propagation of the fracture is controlled by supplying fracture fluid independent to the two opposing wings of the hydraulic fracture. The injection casing initiation section remains open after fracturing providing direct hydraulic connection between the production well bore, the permeable proppant filled fracture and the formation.

摘要： The present invention involves a method and apparatus for enhanced recovery of petroleum fluids from the subsurface by injection of a steam and hydrocarbon vaporized solvent in contact with the oil sand formation and the heavy oil and bitumen in situ. Multiple propped hydraulic fractures are constructed from the well bore into the oil sand formation and filled with a highly permeable proppant. Steam, a hydrocarbon solvent, and a non-condensing diluent gas are injected into the well bore and the propped fractures. The injected gas flows upwards and outwards in the propped fractures contacting the oil sands and in situ bitumen on the vertical faces of the propped fractures. The steam condenses on the cool bitumen and thus heats the bitumen by conduction, while the hydrocarbon solvent vapors diffuse into the bitumen from the vertical faces of the propped fractures. The bitumen softens and flows by gravity to the well bore, exposing fresh surface of bitumen for the process to progressively soften and mobilize the bitumen in a predominantly circumferential, i.e. orthogonal to the propped fracture, diffusion direction at a nearly uniform rate into the oil sand deposit. The produced product of oil and dissolved solvent is pumped to the surface where the solvent can be recycled for further injection.

摘要： The present invention is a method and apparatus for the enhanced recovery of petroleum fluids from the subsurface by in situ combustion of the hydrocarbon deposit, from injection of an oxygen rich gas and drawing off a flue gas to control the rate and propagation of the combustion front to be predominantly horizontal and propagating vertically downwards guided by the vertical highly permeable hydraulic fractures. Multiple propped vertical hydraulic fractures are constructed from the well bore into the oil sand formation and filled with a highly permeable proppant containing hydrodesulfurization and thermal cracking catalysts. The oxygen rich gas is injected via the well bore into the top of the propped fractures, the in situ hydrocarbons are ignited by a downhole burner, and the generated flue gas extracted from the bottom of the propped fractures through the well bore and mobile oil gravity drains through the propped fractures to the bottom of the well bore and pumped to the surface. The combustion front is predominantly horizontal, providing good vertical and lateral sweep, due to the flue gas exhaust control provided by the highly permeable propped fractures.

摘要： The present invention involves a method and apparatus for enhanced recovery of petroleum fluids from the subsurface by injecting a hydrocarbon solvent vapor in contact with the oil sand formation and the heavy oil and bitumen in situ. Multiple propped vertical hydraulic fractures are constructed from the well bore into the oil sand formation. The hydrocarbon solvent vapor and a non-condensing diluent gas are injected into the well bore, fill the hydraulic fractures, and thus contact and diffuse into the in situ bitumen. The hydrocarbon solvent vapors diffuse into the bitumen from the vertical faces of the propped fractures. The bitumen softens and flows by gravity to the well bore, exposing fresh surface of bitumen for the process to progressively soften and mobilizes the bitumen in a predominantly circumferentially, i.e. orthogonal to the propped fracture, diffusion direction at a nearly uniform rate into the oil sand deposit. The mobile oil may be deasphalted by the condensed solvent, leaving the heavy asphaltenes behind in the oil sand pore space with little loss of inherent fluid mobility in the processed oil sands. The processed product is produced with the dissolved solvent along with a tail diluent gas. The tail diluent gas is enriched with hydrocarbon solvent and re-injected into the process zone and the cycle repeated.
