Abstract
Systems and methods presented herein generally relate to a method that includes receiving water at a centralized facility. The method also includes receiving sand from one or more sand mines at the centralized facility. The method further includes receiving one or more chemicals at the centralized facility. In addition, the method includes using processing equipment of the centralized facility to process the water, the sand, and the one or more chemicals to produce a fracturing slurry. The method also includes conveying the fracturing slurry from the centralized facility to one or more fracturing sites.
Claims20
A method, comprising:
- receiving water at a centralized facility;
- receiving sand from one or more sand mines at the centralized facility;
- receiving one or more chemicals at the centralized facility;
- using processing equipment of the centralized facility to process the water, the sand, and the one or more chemicals to produce a fracturing slurry, wherein using the processing equipment comprises:
- using a low-shear addition system to add a friction-reducing additive to the fracturing slurry, wherein using the low-shear addition system comprises using at least one eductor to disperse the friction-reducing additive into the fracturing slurry;
- and
- conveying the fracturing slurry from the centralized facility to one or more fracturing sites.
A method, comprising:
- receiving water at a centralized facility via one or more water pipelines;
- receiving sand from one or more sand mines at the centralized facility via one or more sand pipelines;
- receiving one or more chemicals at the centralized facility;
- using processing equipment of the centralized facility to process the water, the sand, and the one or more chemicals to produce a fracturing slurry, wherein using the processing equipment comprises:
- using a dilution manifold to dilute concentrations of the sand, the one or more chemicals, or both, in the fracturing slurry;
- using dewatering equipment to remove water from the fracturing slurry;
- using blending equipment to add water into the fracturing slurry;
- or
- using a low-shear addition system to add a friction-reducing additive to the fracturing slurry;
- or
- a combination thereof;
- and
- conveying the fracturing slurry from the centralized facility to one or more fracturing sites via one or more fracturing slurry pipelines, wherein the one or more fracturing slurry pipelines comprise a textured, interior surface that facilitates passive mixing of the fracturing slurry.
A method, comprising:
- receiving produced water from one or more well sites at a centralized facility via one or produced water pipelines;
- receiving sand from one or more sand mines at the centralized facility via one or more sand pipelines;
- receiving one or more chemicals at the centralized facility;
- and
- conveying the produced water, the sand, and the chemicals from the centralized facility to one or more fracturing sites via one or more fracturing slurry pipelines and processing equipment of the centralized facility, wherein:
- movement of the produced water, the sand, and the one or more chemicals through the one or more fracturing slurry pipelines and the processing equipment passively mixes the produced water, the sand, and the one or more chemicals into a fracturing slurry without using active mixing equipment;
- and
- the processing equipment comprises:
- a low-shear addition system to add a friction-reducing additive to the fracturing slurry, wherein the low-shear addition system comprises at least one eductor to disperse the friction-reducing additive into the fracturing slurry.
