Abstract: A system and methodology facilitates the handling of oilfield materials in a space efficient manner. The oilfield materials are delivered without blowers to at least one modular silo. Each modular silo comprises an outer housing defining an enclosed interior. A vertical conveyor is positioned within the enclosed interior and is used to lift the oilfield material from a silo inlet to an upper portion of the modular silo without utilizing airflow to carry the oilfield materials. Once the oilfield materials are disposed within the upright modular silo, the outflow of oilfield materials through a silo outlet may be controlled so as to selectively release the desired amount of material into a blender or other suitable equipment.

Abstract: A multi-tank system for preparing fluids for hydraulic fracturing of reservoirs and methods of injecting the prepared fluid upstream from pumping units are disclosed. The multi-tank system allows for a proppant slurry to be continuously formed and mixed with a proppant carrier in staggered phases to form a fracturing fluid. This fracturing fluid can then be injected into the reservoir at normal injection pressures, thus reducing wear and downtime on the blender, and allowing continuous flow of proppant.
