摘要： Methods and systems for integral storage and blending of the materials used in oilfield operations are disclosed. A modular integrated material blending and storage system includes a first module comprising a storage unit, a second module comprising a liquid additive storage unit and a pump for maintaining pressure at an outlet of the liquid additive storage unit. The system further includes a third module comprising a pre-gel blender. An output of each of the first module, the second module and the third module is located above a blender and gravity directs the contents of the first module, the second module and the third module to the blender. The system also includes a pump that directs the output of the blender to a desired down hole location. The pump may be powered by natural gas or electricity.

摘要： Methods and systems for blending fluids used in subterranean operations are disclosed. A first portion of a fluid component of the slurry is passed through a non-slurry pump (108) in a first process line (102). A second portion of the fluid component of the slurry is passed to a mixing tub (118) in a second process line (104). A solid component is added to the second portion of the fluid component of the slurry in the mixing tub. The second portion of the fluid component of the slurry is mixed with the solid component in the mixing tub so that the second portion of the fluid component of the slurry has a higher concentration than a desired downhole concentration. The output of the mixing tub is pumped through a slurry pump (122). The output of the slurry pump is diluted by adding the first portion of the fluid component of the slurry from the first process line and the diluted mixture is directed to a high pressure pump.
