    摘要: A crossover tool for use with concentric tubing strings. The apparatus disclosed provides the ability to treat and/or gravel pack a producing zone in a well, and is particularly suited for use in a multiple-zone well. The crossover tool may be locked in any one of three positions: a circulate mode, a closed test mode, or a closed bypass mode to facilitate movement of the tool within the well bore. All operation of the crossover tool is effected by reciprocation of the pipe string to which it is attached. Alternative embodiments are also disclosed which dispense with the closed test mode.

    摘要: A method of gravel packing multiple zones with a single trip of the operating string into a well without inducing fluid movement across zones, and without disturbing the zone being packed in reverse circulation. Apparatus is disclosed to perform the method, comprising a screen liner assembly surrounding a concentric operating string. Mechanical force on the operating string is used to change all tool modes of the apparatus. The operating string is accurately positioned with respect to the screen liner assembly at every zone level and zones may be easily relocated if necessary. Zones may be packed in any order, and a zone may be repacked, if necessary, during the same trip into the well.

    摘要: Disclosed herein are methods and apparatus for releasing a releasable packer. The apparatus may include shear screws, a mechanism for isolating the shear screw from a shearing force. The mechanism for isolating the shear screw from a shearing force is selectively unlockable to expose the shear screw to the shearing force. The methods may include unlocking a mechanism protecting at least one shear screw, applying a shearing force to the at least one shear screw, and shearing the at least one shear screw.

    摘要: A transmission is provided having a dual clutch, to achieve torque flow through a countershaft gearing arrangement. The countershaft gearing arrangement includes a plurality of co-planar gear sets having gears that are selectively connectable to a first and second countershaft. A transfer gear set transfers torque from the countershaft to an output shaft. The output shaft is connected to a final drive unit that has a final drive unit output shaft that is transverse to an input member connected at one end to a torque converter and at the other end to the dual clutch.

    摘要: A computer-implemented method for managing participants of a marketing campaign is disclosed. The method includes generating a marketing campaign with multiple tracks. Each track comprises one or more steps that indicate an activity executed on campaign participants. The method also includes generating segmentation conditions based on natural language statements. Each segmentation condition includes a rule and a time condition. Additionally, the method includes associating a campaign participant from a first track to a second track if behavior information satisfies a segmentation condition. The behavior information includes a response by the campaign participant to an activity indicated by a step in the first track.
