摘要： Initiation of injection planes in a well. A method of forming at least one generally planar inclusion in a subterranean formation includes the steps of: expanding a wellbore in the formation by injecting a material into an annulus positioned between the wellbore and a casing lining the wellbore; increasing compressive stress in the formation as a result of the expanding step; and then injecting a fluid into the formation, thereby forming the inclusion in a direction of the increased compressive stress. Another method includes the steps of: expanding a wellbore in the formation by injecting a material into an annulus positioned between the wellbore and a casing lining the wellbore; reducing stress in the formation in a tangential direction relative to the wellbore; and then injecting a fluid into the formation, thereby forming the inclusion in a direction normal to the reduced tangential stress.

摘要： A well tool can comprise a fluid input, a fluid output and a fluidic oscillator which produces oscillations in a fluid which flows from the input to the output. The fluidic oscillator can include a vortex chamber with inlets, whereby fluid enters the vortex chamber alternately via the inlets, the inlets being configured so that the fluid enters the vortex chamber in different directions via the respective inlets, and a fluid switch which directs the fluid alternately toward different flow paths in response to pressure differentials between feedback fluid paths. The feedback fluid paths may be connected to the vortex chamber. The flow paths may cross each other between the fluid switch and the outlet.

摘要： Systems and methods for thermal recovery of shallow bitumen using increased permeability inclusions. A method of producing hydrocarbons from a subterranean formation includes the steps of: propagating at least one generally planar inclusion outward from a wellbore into the formation; injecting a fluid into the inclusion, thereby heating the hydrocarbons; and during the injecting step, producing the hydrocarbons from the wellbore. 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： Systems and methods for drainage of a heavy oil reservoir via a horizontal wellbore. A method of improving production of fluid from a subterranean formation includes the step of propagating a generally vertical inclusion into the formation from a generally horizontal wellbore intersecting the formation. The inclusion is propagated into a portion of the formation having a bulk modulus of less than approximately 750,000 psi. A well system includes a generally vertical inclusion propagated into a subterranean formation from a generally horizontal wellbore which intersects the formation. The formation comprises weakly cemented sediment.

摘要： Casing deformation and control for inclusion propagation in earth formations. A method of forming at least one inclusion in a subterranean formation includes the steps of: installing a liner within a casing section in a wellbore intersecting the formation; and expanding the liner and the casing section, thereby applying an increased compressive stress to the formation. Another method of forming the inclusion includes the steps of: installing an expansion control device on a casing section, the device including at least one latch member; expanding the casing section radially outward in a wellbore, the expanding step including widening at least one opening in a sidewall of the casing section, and displacing the latch member in one direction; and preventing a narrowing of the opening after the expanding step, the latch member resisting displacement thereof in an opposite direction.

摘要： Flow control for increased permeability planes in unconsolidated formations. A well system includes a casing expansion device interconnected in a casing string for initiating an inclusion propagated into a formation surrounding the casing string. The device has at least one opening in a sidewall for fluid communication between the inclusion and an interior of the casing string. A flow control device is retrievably installed in the expansion device and controls flow between the formation and an interior of the casing string. A method of controlling flow of fluid between a formation and an interior of a casing string includes the steps of interconnecting a casing expansion device in the casing string; expanding the device to thereby initiate propagation of an inclusion into the formation; and installing a flow control device in the expansion device to thereby control flow between the inclusion and the casing string interior.
