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 phase change fluid spring (450) for actuating a downhole tool (50) in a wellbore. The phase change fluid spring (450) includes a housing (114) defining a fluid chamber (120) and a phase change fluid disposed within the fluid chamber (120). The phase change fluid is in a first phase and at a first pressure at the surface. The phase change fluid is in a second phase and at a second pressure in the wellbore, the second pressure being greater than the first pressure. The phase change fluid is operable to store and release energy downhole to actuate the downhole tool (50).

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： An apparatus, system and method are provided for measuring state properties without requiring an internal or proximate power supply. The apparatus provides a sensing device that is responsive to fluctuations in a state property that are encountered within the test zone. Due to the fluctuations experienced by the sensing device, a sensing signal is generated and transmitted to an optical device, such as an interferometer. The sensing signal's affect on the optical device produces an interference pattern that may be detected remotely and correlated to the fluctuation experienced by the sensing device.

摘要： The present disclosure addressed apparatus and methods for forming an annular isolator in a borehole after installation of production tubing. Annular seal means are carried in or on production tubing as it is run into a borehole. In conjunction with expansion of the tubing, the seal is deployed to form an annular isolator. An inflatable element carried on the tubing may be inflated with a fluid carried in the tubing and forced into the inflatable element during expansion of the tubing. Reactive chemicals may be carried in the tubing and injected into the annulus to react with each other and ambient fluids to increase in volume and harden into an annular seal. An elastomeric sleeve, ring or band carried on the tubing may be expanded into contact with a borehole wall and may have its radial dimension increased in conjunction with tubing expansion to form an annular isolator.

摘要： A screen assembly (38) and method for progressively treating an interval (48) of a wellbore (32) is disclosed. The screen assembly (38) comprises a sand control screen (40) that is positioned within the wellbore (32) and a plurality of diverter members (42) that are positioned along the sand control screen (40). During a treatment process when a treatment fluid is pumped into the interior of the sand control screen (40), the diverter members (42) progressively allow the treatment fluid to exit from the interior of the sand control screen (40) to the exterior of the sand control screen (40) from a first end (46) of the interval (48) to a second end (44) of the interval (48) to progressively treat the interval (48) of the wellbore (32).

摘要： Electrical power generators and methods of producing power in a subterranean well are provided. In a described embodiment, fluid flow through a fluid conduit causes a member to displace or vibrate. The displacement of the member is utilized to induce strain in a piezoelectric material, thereby causing the piezoelectric material to produce electricity. Various means may be used to create turbulence in the fluid flow, thereby increasing displacement of the member, resulting in increased power output from the generator.

摘要： An apparatus and method for monitoring and reporting downhole bit failure. Sensors are located on a sub assembly (which is removable from the drill bit) and send data to neural net or other adaptive filter. The neural net uses past sensor readings to predict future sensor readings. The value predicted for the sensors is subtracted from the actual value to produce a prediction error. Increases in prediction error are used to indicate bit failure. The results of this are transmitted to the operator by varying the pressure in the drilling mud flow.
