Abstract: A process of managing inventory and delivery logistics of one or more chemical additives used at a well treatment site. The process includes placing one or more bulk containers at the well treatment site to maintain inventory capacity for one or more chemical additives on-site for a well treatment procedure. Monitoring chemical additive inventory within the one or more bulk containers. Making a determination, based on monitored chemical additive inventory, whether additional additive is needed in the one or more bulk containers; generating, based on the determination, initiation of an order for delivery of additional additive. delivering the additional additive in a delivery bulk container to the well treatment site. Also included is an automated additive inventory and delivery logistics control system.

Abstract: Automatically adjusting the amount of material delivered by a conveyor belt includes measuring the speed of a drive pulley that drives the conveyor belt and determining the weight of material dispensed onto the conveyor belt from at least one material dispenser on a real-time, ongoing basis. Based at least in part upon such speed and weight measurements, an electronic controller repeatedly adjusts the speed of the conveyor belt by dictating the output of at least one motor that drives the drive pulley.

Abstract: At least one probe assembly is used to measure the height of material dispensed into the bin of a hopper assembly.

Abstract: Apparatus and methods for assisting in controlling the supply of material onto a conveyor from a material dispenser include the use of a discharge control device coupled to each dispenser gate of the material dispenser. The discharge control device includes at least one wiper configurable to level the top of at least some of the material dispensed onto the conveyor through the material dispenser.

Abstract: A proppant delivery system for a fracturing fluid blending system. The proppant delivery system includes an automatic feed-screwless proppant dispensing unit configured to deliver proppant directly to a blender opening of a blender. A weighing device on an upstream side of the blender configured to weigh the proppant during delivery of the proppant to the blender. Also included is a method of delivering proppant to a fracturing fluid blender.

Abstract: In some embodiments, apparatus useful for assisting in controlling the discharge of material onto a conveyor from a material dispenser includes a carrier, first and second side restrictors extending downwardly from the carrier and at least one wiper extending downwardly from the carrier and transverse to the side restrictors. The side restrictors are configured to assist in preventing at least some material from overflowing off the sides of the conveyor, while the wiper is configured to level the top of at least some of the material dispensed on the conveyor.

Abstract: Method of controlling the amount of material delivered by conveyor belt includes measuring the speed of the conveyor belt or a drive pulley that drives the conveyor belt. A weighing device weighs material dispensed onto the conveyor belt from at least one material dispenser. Based at least in part upon such speed and weight measurements, an electronic controller maintains or changes the speed of the conveyor belt by dictating the output of at least one motor that drives the drive pulley.
