    摘要： Apparatus and method for controlling an unswept volume in a piston system. The method includes rotating a shaft around a rotation point to drive a piston within a cylindrical volume in a periodic manner, modifying the stroke length of the piston, and moving the center of the shaft relative to the cylindrical volume such that a change in an unswept volume or compression ratio is controlled.

    摘要： A reciprocating apparatus for pumping pressurized fluid. The reciprocating apparatus comprises a plunger disposed within a cylinder, wherein the plunger is hollow and ported for enabling fluid within the cylinder to flow into the plunger. The plunger includes at least one outlet through which fluid within the plunger flows out of the plunger. In operation, the plunger retracts to displace fluid from the hollow body and into a discharge chamber, and the plunger extends towards the discharge chamber to discharge the displaced fluid. As the plunger alternately retracts and extends, fluid within the plunger continuously flows towards the discharge chamber.

    摘要： Changes occurring downhole during a fracturing process can create or reflect pressure signals. Capturing and evaluating such pressure waves during fracturing enables personnel to monitor, in real time or later, what happens downhole. When a fracture extends, a burst of acoustic noise is embodied in a pressure wave or signal, as is noise coming from other sources. By transforming time-based pressure signals to a frequency base, one can monitor this acoustic noise. In a particular implementation, a waterfall plot of frequency spectra at successive time slices of the original signal is used to determine frequency ridges, such as a ridge of decreasing frequencies indicates fracture extension and a ridge of increasing frequencies indicates either closure or proppant backing up in the fracture. Filtering, such as wavelet filtering, can be used. A fracturing process can be controlled in response to determining whether the fracture is extending.

    摘要： A method for generating an artificial neural network ensemble for determining stimulation design parameters. A population of artificial neural networks is trained to produce one or more output values in response to a plurality of input values. The population of artificial neural networks is optimized to create an optimized population of artificial neural networks. A plurality of ensembles of artificial neural networks is selected from the optimized population of artificial neural networks and optimized using a genetic algorithm having a multi-objective fitness function.
