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.

Mobile support structure for bulk material containers

Systems and methods for using one or more pre-filled, portable containers, instead of pneumatic transfer, to move bulk material from a transportation unit to a blender receptacle of a blender are provided. A transportation unit may deliver one or more containers of bulk material to the well site, where the containers may be disposed in an elevated position around the blender receptacle. A gravity feed outlet may extend from one or more containers to route bulk material from the one or more containers directly into the blender receptacle. Since the transportation unit is able to unload the portable containers of bulk material without pneumatic transfer, the stackable containers may enable a cleaner and more efficient bulk material transfer at the site.

Container bulk material delivery system

In accordance with presently disclosed embodiments, systems and methods for determining the amount of bulk material being choke-fed into an inlet of a blender from one or more bulk material containers placed on a support structure are disclosed. The system includes sensors placed on the support structure beneath the one or more containers for determining the amount of bulk material contained within the container at any given time. By monitoring the change in the mass of the material in the containers overtime the amount of material being fed into the blender can be determined. The material is metered into a mixer within the blender using a metering mechanism, such as a sand screw, which supplies a fixed capacity of bulk material into the blender. The ability to precisely measure the amount of bulk material being choke-fed into the blender enables operators to calibrate the sand screw continuously.

A pumping system pumps material downhole, for example, to perform a fracturing operation. The pumping system comprises one or more variable speed engines, one or more variable displacement hydraulic pumps and one or more intensifiers. According to the desired or required load, the speed of the engine is set at an optimal or most efficient operating speed. The volumetric displacement of the variable displacement hydraulic pump is set to provide the desired output volume and pressure of the material from the intensifier. Varying the speed of the engine and the volumetric displacement of the variable displacement pump allows for the pumping system and in particular the engine to operate at an optimal efficiency which reduces at least fuel costs and wear and tear on components.

In accordance with presently disclosed embodiments, systems and methods for sequencing portable containers of bulk material to provide continuous bulk material usage at an outlet are provided. The disclosed sequencing techniques may involve identifying a sequence for opening different portable containers of bulk material (or identifying the 'next' portable container to open) and automatically actuating the discharge gates of the portable containers in the desired sequence to provide a continuous flow of bulk material to the outlet (e.g., blender unit). The identified sequence may be executed through a control system communicatively coupled to actuators used to open/close the discharge gates of the portable bulk material containers. A GUI may be communicatively coupled to the control system to allow an operator to select the desired sequence for execution by the control system and to display information regarding the portable bulk material containers.

Systems and methods for managing bulk material efficiently at a well site are provided. The disclosure is directed to a container support frame that is integrated into a blender unit. The support frame is used to receive one or more portable containers of bulk material, and the blender unit may include a gravity feed outlet for outputting bulk material from the containers directly into a mixer of the blender unit. The blender unit with integrated support frame may eliminate the need for any subsequent mechanical conveyance of the bulk material (e.g., via a separate mechanical conveying system or on-blender sand screws) from the containers to the mixer. As such, the integrated blender unit may be lighter weight, take up less space, and have a lower cost and complexity than existing blenders.

In accordance with presently disclosed embodiments, systems and methods for efficiently managing bulk material are provided. The disclosure is directed to systems and methods for efficiently combining additives into bulk material being transferred about a job site. The systems may include a support structure used to receive one or more portable containers of bulk material, and a mulling device disposed beneath the support structure to provide bulk material treatment capabilities. Specifically, the mulling device may facilitate mixing of coatings or other additives with bulk material that is released from the portable containers, as well as transfer of the mixture to an outlet location.

Electrically ignitable and electrically controllable explosive material (EIECEM) may be disposed within a shaped charge for deployment downhole. An explosion of the EIECEM is controlled by limiting the duration of excitation at the EIECEM, for example, the duration that an electrical source provides an electrical charge, electrical current or electrical signal. The shaped charge may be insulated from an electrical source to prevent explosion of the EIECEM and coupled to the electrical source to create ignite or explode the EIECEM. A plurality of shaped charges may be disposed downhole and may be ignited or exploded in any suitable order. The EIECEM may be ignited multiple times such that multiple explosions are created. The explosion of the EIECEM creates or extends a perforation or fracture in a formation. The shaped charges may be excited in a predetermined sequence and for a predetermined duration of time.
