    摘要: A formation fluid evaluation system (800) interconnected within a tubular string (818) for operation in a wellbore (802) having multiple zones (806, 808, 810). The evaluation system (800) includes a set of straddle packers (820, 822) that is operable to sequentially isolate the multiple zones (806, 808, 810). A test valve (824) is disposed between the straddle packers (820, 822). A fluid unloading assembly (828) is positioned uphole of the straddle packers (820, 822). The fluid unloading assembly (828) is operable to draw fluid (834) from the isolated zone (808) into the tubular string (818) through the test valve (824) in response to the circulation of a drive fluid down the tubular string (818). A formation evaluation instrument (836) is disposed within the tubular string (818) and determines a characteristic of the fluid (834) received from the isolated zone (808).

    摘要: A multi-channel downhole telemetry system for enabling communication in a wellbore. The system includes a downhole transmitter operable to optically transmit a first data stream on a first optical channel and a second data stream on a second optical channel. A downhole receiver is operable to receive the first data stream and the second data stream. An optically transmissive fluid disposed in the wellbore provides a medium for the optical transmission of the first data stream and the second data stream between the downhole transmitter and the downhole receiver. The optically transmissive fluid contains suspended solids having refraction surfaces that scatter the optically transmitted data streams in the wellbore.

    摘要: A well tool can comprise a fluid input, a fluid output and a fluidic oscillator which produces oscillations in a fluid which flows from the input to the output. The fluidic oscillator can include a vortex chamber with inlets, whereby fluid enters the vortex chamber alternately via the inlets, the inlets being configured so that the fluid enters the vortex chamber in different directions via the respective inlets, and a fluid switch which directs the fluid alternately toward different flow paths in response to pressure differentials between feedback fluid paths. The feedback fluid paths may be connected to the vortex chamber. The flow paths may cross each other between the fluid switch and the outlet.

    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.
