Electric or natural gas fired small footprint fracturing fluid blending and pumping equipment

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.

主权项

1. An integrated material blending and storage system comprising:
a storage unit; a blender located under the storage unit; wherein the blender is operable to receive a first input from the storage unit through a hopper; a liquid additive storage module having a first pump to maintain constant pressure at an outlet of the liquid additive storage module; wherein the blender is operable to receive a second input from the liquid additive storage module; and a pre-gel blender, wherein the pre-gel blender comprises at least a pre-gel storage unit resting on a leg, further wherein the pre-gel storage unit comprises a central core and an annular space, wherein the annular space hydrates the contents of the pre-gel blender; wherein the blender is operable to receive a third input from the pre-gel blender; wherein gravity directs the contents of the storage unit, the liquid additive storage module and the pre-gel blender to the blender; a second pump; and a third pump; wherein the second pump directs the contents of the blender to the third pump; and wherein the third pump directs the contents of the blender down hole; wherein at least one of the second pump and the third pump is powered by one of natural gas and electricity.
