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: A system for delivering hydraulic fracturing fluid to a wellbore is provided. The system includes a first frac tree connected to a first wellbore and a second frac tree connected to second wellbore. The system further includes a zipper module and a first single straight-line connection between the zipper module and the first frac tree. The system also includes a second single straight-line connection between the first frac tree and the second frac tree.

Abstract: A combination pet leash and exercise apparatus that is configured to be utilized in a first configuration and a second configuration. In the first configuration the present invention is utilized to walk a pet. In the second configuration the present invention provides a resistance exercise for the user. A first member and a second member are adjacent to each other and releasably secured in the first configuration. The first member is a nylon strap and the second member is an elastic tube. Fasteners are present at each end of the first member and second member and are secured to ring members in the first configuration. A handle member is secured to the first ends of the first member and second member in the first configuration. In the second configuration handle member is released from operable engagement with the first member so as to be only coupled to the second member.
