    摘要： A method of controlling fluid loss from a wellbore comprises the steps of: installing a completion string including a well screen and a fluid loss control device in the wellbore; then installing a production string in the wellbore; then engaging the production string with the completion string; and then operating the fluid loss control device by varying pressure in a fluid passage. A well system comprises a completion string including a fluid loss control device, a packer and a well screen, the packer being positioned between the fluid loss control device and the screen; and a production string including another packer and engaged with the completion string, the fluid loss control device being positioned longitudinally between the packers, and the fluid loss control device being operable in response to variation of pressure in a fluid passage.

    摘要： A valve device and associated methods of selectively communicating between an interior and an exterior of a tubular string. A valve device includes an openable and closable flowpath for selectively permitting and preventing flow between an interior and exterior of the valve device, and a lock assembly which prevents the flowpath from being opened greater than a predetermined number of times. A method of testing at least one annular seal in an annulus formed between a tubular string and a wellbore wall includes the steps of: sealingly engaging the annular seal to thereby prevent flow through the annulus across the annular seal; and applying a pressure differential across the annular seal to thereby test the annular seal, the pressure differential being applied via a valve device interconnected in the tubular string

    摘要： A packer or bridge plug is described which may be released by manipulation of the production tubing connected to it. If manipulation of the production tubing is unsuccessful in releasing the packer, the tensile strength of the production tubing need not be exceeded in attempting to remove the packer. Instead, the production tubing is removed along with certain internal components of the packer. Thereafter, heavy-wall tubing, with or without jars, can be lowered into the wellbore with a retrieving tool at the bottom of that string. The retrieving tool latches onto components of the packer to allow an alternative method of release which allows for use of significantly higher tensile loads to liberate the packer from the wellbore.

    摘要： A hydraulically set well packer. The setting sleeve is releasably locked to the packer mandrel to prevent premature setting while the packer is being lowered to its desired downhole location. The setting sleeve is unlocked by increasing fluid pressure within the packer mandrel above a preselected value. The length of the setting sleeve can be easily adjusted to accommodate additional piston units, changes in mandrel length, and various packing elements.

    摘要： Inflow control devices for sand control screens. A well screen includes a filter portion and at least two flow restrictors configured in series, so that fluid which flows through the filter portion must flow through each of the flow restrictors. At least two tubular flow restrictors may be configured in series, with the flow restrictors being positioned so that fluid which flows through the filter portion must reverse direction twice to flow between the flow restrictors. A method of installing a well screen includes the step of accessing a flow restrictor by removing a portion of an inflow control device of the screen.
