A flow system is used to mix and transport a slurry of sand and water in support of a hydraulic fracturing operation that is to be conducted at a well site location. The flow system utilizes lay-flat hose to transport the slurry under motive force provided by one or more centrifugal pumps. The lay-flat hose may be constructed in total lengths exceeding several miles in length and may be provided to place a mobile mine in fluidic communication with the well site location.
A straining system is provided to facilitate the removal of rocks and other debris from wet, unprocessed sand that is used as proppant during hydraulic fracturing operations which are well stimulation operations that are performed as an instrumentality for stimulation to achieve enhanced flow rates in and from wells, such as oil, gas, water, injection, or geothermal wells. The straining system has an intake manifold that is configured to accept frac fluid from a blender and a discharge manifold that is configured to discharge strained frac fluid to an array of frac pumps. An internal flow pathway places the intake manifold in fluidic communication with the discharge manifold. The flow pathway includes a strainer basket for the removal of debris that may be entrained in the frac fluid emanating from the blender.
An automated gate actuator system is provided for use in selectively opening and closing a gate that dispenses proppant from a proppant container during the course of a hydraulic fracturing operation. A lever arm is pivotally mounted for movement to place a drive gear in contact with a driven gear to open and close the gate. The gate may be remotely or autonomously actuated in this manner utilizing an electronic control triggered by human and/or sensor input.

An intermodal container for transporting frac proppant, such as frac sand, and/or other types of granular material is disclosed. The intermodal container is designed to receive frac sand from a quarry or other frac sand supply source. Once the container is filled with material, the container is loaded onto a transportation device and transported to a well site. Once received at the well site, the containers can be stacked and the frac sand stored until needed. Once the frac sand is needed, the containers are placed on a base unit and the container discharges its contents onto a conveying system formed as part of the base unit. The conveying system directs the frac sand to a blending location. The empty intermodal containers can be removed from the base unit and loaded onto a transportation device to be refilled at a mine site.
