Abstract: A system can include one or more processors; memory; a data interface that receives data; a control interface that transmits control signals for control of pumps of a hydraulic fracturing operation; and one or more components that can include one or more of a modeling component that predicts pressure in a well fluidly coupled to at least one of the pumps, a pumping rate adjustment component that generates a pumping rate control signal for transmission via the control interface, a capacity component that estimates a real-time pumping capacity for each individual pump, and a control component that, for a target pumping rate for the pumps during the hydraulic fracturing operation, generates at least one of engine throttle and transmission gear settings for each of the individual pumps using an estimated real-time pumping capacity for each individual pump where the settings are transmissible via the control interface.

Abstract: An apparatus and method are disclosed for measuring a rheology indicator in a rheometer utilizing a rheometer attachment including a shaft having a shaft axis, an outer surface, and a plurality of helical vanes each extending radially from the outer surface.

Abstract: The application is directed to a hydraulic fracturing method and can be used for enhancement of the well production. The method for enhancement of fracture conductivity comprises the chemical treatment of the fracture surface and the space between the proppant pillars over the protective mask formed by material precipitated out from the proppant pillar.

Abstract: The invention relates to the area of oil-and-gas production, based on hydraulic fracturing method and can be used for enhancement of the well production. The method for enhancement of fracture conductivity comprises the chemical treatment of the fracture surface and the space between the proppant pillars over the protective mask formed by material precipitated out from the said proppant pillar.
