Hydraulic fracturing spread and mechanisms

Abstract

A hydraulic fracturing spread system has modular high-pressure fracturing fluid manifold assemblies which couple to form a large trunk line for collecting and conveying high pressure fracturing fluid toward the well bore. Oil-hydraulic intensifier pump units integrated with the modular manifold assemblies increase the fracturing fluid pressure into the trunk line. The manifold assemblies may be configured differently from one to the other and coupleable horizontally and/or vertically.

What is claimed is: 
     
         1 . A hydraulic fracturing spread layout system, comprising:
 a plurality of oil-hydraulic pumping units, each oil-hydraulic pumping unit comprising one or more pump actuators and one or more oil-hydraulic pumps;   wherein a plurality of oil-hydraulic pumps are coupled to, and drive, an individual intensifier unit of a manifold assembly, the manifold assembly further comprising a high-pressure trunk line to supply fracturing fluid to a well bore.   
     
     
         2 . The hydraulic fracturing spread layout system of  claim 1 , further comprising a control valve on each oil-hydraulic pumping unit. 
     
     
         3 . The hydraulic fracturing spread layout system of  claim 1 , further comprising one or more control valves on the manifold assembly. 
     
     
         4 . The hydraulic fracturing spread layout system of  claim 1 , further comprising a plurality of manifold assemblies, wherein the plurality of manifold assemblies are vertically coupled to one another. 
     
     
         5 . The hydraulic fracturing spread layout system of  claim 1 , further comprising a plurality of manifold assemblies, wherein the plurality of manifold assemblies are adjacent to one another and horizontally coupled to one another. 
     
     
         6 . The hydraulic fracturing spread layout system of  claim 1 , further comprising a plurality of manifold assemblies, wherein a first number of the plurality of manifold assemblies are adjacent to one another and horizontally coupled to one another and a second number of the plurality of manifold assemblies are vertically stacked and coupled to one another. 
     
     
         7 . The hydraulic fracturing spread layout system of  claim 1 , wherein the one or more pump actuators each comprise a diesel engine, a natural gas engine, a turbine, or a motor. 
     
     
         8 . The hydraulic fracturing spread layout system of  claim 1 , wherein the manifold assembly comprises a skid.
