Solution Overview

Problem

In oilfield operations, space constraints and high energy consumption are exacerbated by the need for extensive equipment and long-distance transfer of materials, particularly in fracturing operations, where bulk materials and chemicals are moved from central storage units to blending equipment, contributing to energy consumption and environmental impact.

Innovation Solution

An integrated material blending and storage system comprising storage units, a blender located beneath them, a liquid additive storage module with a pump for maintaining constant pressure, and a pre-gel blender, where gravity directs contents to the blender, reducing the need for conveyer systems and energy-intensive transfers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If materials are stored in central storage units and transferred to blending equipment, then material storage capacity is improved, but space availability deteriorates and energy consumption increases

Engineering Contradiction:
Improvematerial storage capacityVSAvoidspace availability
Core Design Contradiction:
Quantity of substanceVSArea of stationary object

Solution Approach 1:

The patent combines storage units and blending equipment into a single integrated system. The storage units are positioned directly above the blender, merging the functions of storage and blending into one compact structure. This eliminates the need for separate storage areas and transfer equipment, thereby improving space availability while maintaining material storage capacity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The storage units are nested vertically above the blender in a compact arrangement. This nesting configuration allows the storage function to be embedded within the overall blending system structure, maximizing space utilization by using vertical space rather than horizontal spread.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If conveyer belts and screw conveyers are used to transfer materials, then material transfer reliability is improved, but energy consumption increases

Engineering Contradiction:
Improvematerial transfer reliabilityVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The storage units are positioned directly above the blender at a height that allows gravity to naturally drive material flow into the blender. This gravitational flow eliminates the need for energy-consuming conveyer belts and screw conveyers, while the direct vertical alignment ensures reliable material transfer without mechanical intervention.

Inventive Principle:
Principle #12Equipotentiality

Solution Approach 2:

The system uses gravity as a free energy source to automatically transfer materials from storage to blending. The materials self-flow downward without requiring external power input, making the transfer process both energy-efficient and reliable through passive gravitational force.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If equipment is mounted on trucks and brought to location, then mobility is improved, but device complexity increases

Engineering Contradiction:
ImprovemobilityVSAvoidequipment complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent integrates multiple equipment functions into a single modular unit that combines storage units, blending equipment, and transfer mechanisms into one assembly. This integrated design can be mounted on a truck as a complete system, maintaining mobility while reducing the overall complexity compared to transporting and assembling multiple separate pieces of equipment at the job site.

Inventive Principle:
Principle #5Merging (Combining)
