    摘要: A fluid discrimination system can include a fluid discriminator which selects through which of multiple outlet flow paths a fluid composition flows, the selection being based on a direction of flow of the fluid composition through the discriminator, and the direction being dependent on a fluid type in the fluid composition. Another fluid discriminator can include a structure 58 which displaces in response to a fluid composition flow, whereby an outlet flow path of the fluid composition changes in response to a change in a ratio of fluids in the fluid composition.

    摘要: A bidirectional downhole fluid flow control system is operable to control the inflow of formation fluids and the outflow of injection fluids. The system includes at least one injection flow control component 112 and at least one production flow control component 114 in parallel with the at least one injection flow control component 112. The at least one injection flow control component 112 and the at least one production flow control component 114 each have direction dependent flow resistance, such that injection fluid flow experiences a greater flow resistance through the at least one production flow control component 114 than through the at least one injection flow control component 112 and such that production fluid flow experiences a greater flow resistance through the at least one injection flow control component 112 than through the at least one production flow control component 114.

    摘要: A system for optimizing a stimulation operation includes an interface to equipment and sensors for performing the stimulation operation. The interface supplies control signals to the equipment and obtains measurement signals from the sensors. The system further includes a short-term optimizer that derives a current job state based at least in part on the measurement signals, and that further adjusts the control signals to optimize a short-term cost function. The short-term cost function includes a difference between the current job state and a desired job state derived from optimized values of a set of decision variables. The system further includes a long-term optimizer module that determines the optimized values based on a long-term cost function, the long-term cost function accounting for at least a long-term reward and a final state cost.

    摘要: In accordance with some embodiments of the present disclosure, a method of vibration control for a wellbore logging tool is disclosed. The wellbore logging tool includes an acoustic transmitter. The method may include providing a braking signal to the acoustic transmitter. The braking signal may be based, at least in part, on at least one prior vibration in the acoustic transmitter. The method may include determining a present vibration in the acoustic transmitter after the braking signal has been provided to the acoustic transmitter. The method may include determining whether to update the braking signal and, if so, updating the braking signal based, at least in part, on the present vibration in the acoustic transmitter.

    摘要: A variable flow resistance system for use with a subterranean well can include a structure which displaces in response to a flow of a fluid composition, whereby a resistance to the flow of the fluid composition changes in response to a change in a ratio of desired to undesired fluid in the fluid composition. Another system can include a structure which rotates in response to flow of a fluid composition, and a fluid switch which deflects the fluid composition relative to at least two flow paths. A method of variably resisting flow in a subterranean well can include a structure displacing in response to a flow of a fluid composition, and a resistance to the flow of the fluid composition changing in response to a ratio of desired to undesired fluid in the fluid composition changing. Swellable materials and airfoils may be used in variable flow resistance systems.
