摘要： The invention comprises a tubing assembly for use in testing an unconsolidated open-hole portion of a well bore located below a cased portion of the well bore and a method of using the assembly. The tubing assembly comprises an elongated tubing string extending from a well surface into the unconsolidated open-hole portion of the open hole, an open-hole packer mounted on the tubing string for use in sealingly engaging the unconsolidated open-hole portion of the well bore, a casing packer mounted on the tubing string between the open-hole packer and the well surface for sealingly engaging the cased portion of the well bore and a sand control device connected to the tubing string below the openhole packer. The assembly may further comprise additional open-hole packers and sand control devices mounted on the tubing string. Segments of the tubing string may be retrievable. The assembly may have one or more tubing disconnects mounted to the tubing string to disconnect segments of the tubing assembly. The tubing string may further comprise a selective flow device for selectively controlling the flow of well fluids from the well bore into the tubing string.

摘要： A well tool assembly and a method of operating same including a clutch which provides a rotary-driving connection between a running tool and well tool mandrel when the running tool is rotated in a first direction (e.g. clockwise) and has cammed surfaces which ride up on complementary cammed surfaces on the mandrel to disengage the clutch when the running tool is rotated in a second (e.g. counterclockwise) or opposite direction. Once the clutch is disengaged, the running tool can be disconnected from the mandrel by rotating the running tool in said first direction. The clutch can be disengaged either hydraulically at the same time a well tool (e.g. a packer) is being hydraulically set or by rotation of the running tool in the second direction in the event the well tool assembly becomes stuck before the assembly reaches its destination.

摘要： A system for completing a wellbore (38) having multiple zones. The system includes a completion (42) having a plurality of landing points defined therein positioned within the wellbore (38). A service tool is axially movable within the completion (42). The service tool is coupled to a pipe string (36) extending from the surface and selectively supported by a movable block (30) above the surface. A subsurface model is defined in a computer operably associated with the wellbore (38). The model is operable to predict the position of the service tool relative to the landing points of the completion (42) based upon a dynamic lumped mass model of the service tool and a dynamic lumped capacitance thermal model of the wellbore environment.
