    Abstract: A method includes positioning a downhole acquisition tool in a wellbore in a geological formation. The method includes operating a pump module to gather information for a fluid outside of the downhole acquisition tool that enters the downhole acquisition tool from a first flowline, a second flowline, or both while the downhole acquisition tool is within the wellbore. Operating the pump module includes controlling a valve assembly to a first valve configuration that enables the fluid to flow into the downhole tool via the first flowline fluidly coupled to a first pump module. Operating the pump module includes controlling a valve assembly to a second valve configuration that enables the fluid to flow into the downhole tool via the second flowline fluidly coupled to a second pump module, and selectively using a turnaround module or a crossover portion disposed between the first flowline and the second flowline to permit discharging the fluid from one flowline to the other flowline by actuating a valve associated with the turnaround module when the first pump module or the second pump module is not in use.

    Abstract: Techniques are described for axial vibration control of wireline tools and cables during logging operations. In undesirable cases the axial vibrations may lead to or exasperate the stick-slip problems of the logging tool. Control systems and strategies to minimize vibrations are described. Techniques are also described for identifying and inhibiting the sticking of the cable. A described system includes a surface actuator and a sensor. The actuator generates an axial wave on the wireline cable which travels down the cable. If there is sticking of the cable, a reflection can also occur at the location of sticking. This shift in the transmission of the wave on the wireline cable is used to identify the onset and/or presence of sticking.

    Abstract translation: 描述了在测井操作期间用于电缆工具和电缆的轴向振动控制的技术。 在不希望的情况下,轴向振动可能导致或者使用测井工具的粘滑问题。 描述了使振动最小化的控制系统和策略。 还描述了用于识别和抑制电缆粘附的技术。 所描述的系统包括表面致动器和传感器。 执行器在电缆上沿导线产生轴向波,该电缆沿着电缆行进。 如果有电缆的粘附,也可能会在粘贴位置发生反射。 使用有线电缆上的波的传输的这种变化来识别粘着的发生和/或存在。
