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： A safety valve system includes a safety valve having an actuator and a line connected to the actuator. The safety valve is operable by opening the line in the well, with the line being free of any connection to a surface control system. Another safety valve system includes multiple safety valves. An actuator of each safety valve is connected to an actuator of another safety valve via a line. A biasing force in each of the actuators is operative to close the respective one of the safety valves in response to opening of the line. The biasing force is produced at least in part by hydrostatic pressure in a well.

摘要： A multicycle hydraulic control valve. A control and actuation system for a well tool includes a control valve having one or more metal-to-metal seals which open while differential pressure exists across the seals to thereby selectively connect pressure sources to an actuator to operate the well tool. Both seals may be closed while a connection between the actuator and the pressure sources is switched by the control valve. The control valve may include a member having areas formed thereon acted upon by various pressures to facilitate operation of the control valve.

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： 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.
