A bulk material dispensing system comprising a portable support structure with portable containers with wet bulk material. Locating each portable container onto the portable support structure couples a transfer member on each portable container to a vibration device on the support structure. Vibration energy is transferred from vibration device to the portable container via the transfer member. The material dispensing system is configured to route the wet bulk material from the portable container to a blender hopper via a material routing path in response to activating the vibration device.

A bulk material container can include a body, having a plurality of side walls, a bottom, a cavity, and an opening, and a first engagement element. The plurality of side walls are coupled to the bottom, and the cavity, which is configured to receive a bulk material, is formed within the plurality of side walls and above the bottom. The opening is formed by the plurality of side walls spatially opposite of the bottom and is configured to discharge the bulk material when the container is at least partially inverted. The first engagement element can be configured to receive one or more prongs of a transportation device or a bulk material unloading device. In some embodiments, the container may also include a second engagement element and/or a third engagement element, for example with the first, second, and/or third engagement elements differing from each other.

Systems and methods for efficiently managing bulk material are provided. The disclosure is directed to a portable support structure used to receive one or more portable containers of bulk material and output bulk material from the containers directly into the blender hopper. The portable support structure may include a frame for receiving and holding the one or more portable bulk material containers in an elevated position proximate the blender hopper, as well as one or more gravity feed outlets for routing the bulk material from the containers directly into the blender hopper. In some embodiments, the portable support structure may be transported to the well site on a trailer, unloaded from the trailer, and positioned proximate the blender unit. In other embodiments, the portable support structure may be a mobile support structure that is integrated into a trailer unit.

A method of determining a dry proppant concentration in a fracturing fluid includes combining a wet proppant with a carrier fluid in a mixer to form the fracturing fluid. The dry proppant concentration of the fracturing fluid leaving the mixer is determined using a moisture content of the wet proppant entering the mixer, wherein use of the moisture content prevents overestimation of the dry proppant concentration. The method can be preformed using a system for injecting fracturing fluid into a borehole, the fracturing fluid including a carrier fluid mixed with a wet proppant including a dry proppant dampened with a dampening liquid. The system includes a mixer operable to receive and mix the carrier fluid and the wet proppant to form the fracturing fluid, a frac pump operable to inject the fracturing fluid into the borehole, and a control system comprising a processor operable to receive a moisture content of the wet proppant before being mixed with the carrier fluid and programmed to determine a dry proppant concentration of the fracturing fluid formed in the mixer using a moisture content of the wet proppant, wherein use of the moisture content prevents overestimation of the dry proppant concentration.

Disclosed are systems and methods for detecting the beginning of a flush volume. A blended fluid is output by a fluid blending apparatus and pumped into a wellbore. The blended fluid transitions from a first composition to a second composition. A blending signal comprising time-varying data relating to characteristics of the blending apparatus or measured from sensors associated with the blending apparatus is received. Based on a first portion of the blending signal corresponding to the first composition, a calibration profile is generated. Based on the calibration profile and a second portion of the blending signal corresponding to the second composition, a transition indicator corresponding to a change in the blended fluid from the first composition to the second composition is determined. Based on the transition indicator, a flush signal indicating the beginning of a flush volume being output by the blending apparatus and pumped into the wellbore is generated.
