    Abstract: A method includes measuring electrical conductivity of a treatment fluid with one or more sensors at various instants of time. The method is further performed by generating one or more signals indicative of the electrical conductivity of the treatment fluid and transmitting the one or more signals to a computer system. The method is further performed by analyzing the one or more signals to determine a phase change in the treatment fluid based upon a positive or negative change in the electrical conductivity of the treatment fluid from a predetermined electrical conductivity range.

    Abstract: A mixing system and method for mixing a wellsite fluid including a mixture is provided. The mixing system includes a mixing unit, feed valves, and a calibrator. The mixing unit includes a mixing tank having mixing bins to pass the mixture therethrough, mixers positionable in the mixing tank, and a driver to drive the mixers. The feed valves selectively permit the components to pass into the mixing tank. The calibrator includes a calibrator sensor that connects to the mixers to measure equipment parameters thereof, and a controller connectable to the calibrator sensor and the feed valves to selectively adjust an amount of the components passing into the mixing tank based on the equipment parameters. The method may involve measuring equipment parameters of the mixers during mixing and calibrating by selectively adjusting an amount of the components passing into the mixing tank based on the measured equipment parameters.

    Abstract: A system and method are disclosed for preparing a treatment fluid and includes charging packets containing an additive encased within a liner to a first container packet storage area of a first container; passing the packets to a packet shredder; breaching the liners of the packets to expose the additive; passing exposed additive to a mixer; passing an aqueous solution to the mixer from a second container; and mixing the exposed additive with the aqueous solution to form the treatment fluid. The first container can also include a first container proppant storage area, and proppant is passed from the first container proppant storage area to the mixer. The treatment fluid can be charged to a well bore penetrating a subterranean formation. The system and method can also include a silo positioned in fluid flow communication with the first container and partitioned into a silo packet storage area and a silo proppant storage area.

    Abstract: A technique for reducing harmonic vibration in a multiplex multi-pump system. The technique includes establishing a lower bound of system specific vibration-related information such as via pressure variation or other vibration indicator. Establishing the lower bound may be achieved through simulation with the system or through an initial sampling period of pump operation. During this time, random perturbations through a subset of the pumps may be utilized to disrupt timing or phase of the subset. Thus, system vibration may randomly increase or decrease upon each perturbation. Regardless, with a sufficient number of sampled perturbations, the lower bound may be established. Therefore, actual controlled system operations may proceed, again employing random perturbations until operation of the system close to the known lower bound is substantially attained.

    Abstract: A pumping system including a plurality of pumps each having a pump fluid outlet, a drive shaft, a prime mover, and fluid displacing members operatively coupled with the drive shaft. A common fluid conduit may be fluidly coupled with each pump fluid outlet. A control system of the pumping system includes position sensors operable to generate information relating to phase and/or speed of each pump, pressure sensors operable to generate information relating to fluid pressure spikes, and a controller in communication with the position and pressure sensors. The controller is operable to cause the prime movers to adjust the phasing of the pumps with respect to each other, based on the information relating to fluid pressure spikes, and synchronize the speed of the pumps.
