Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If traditional fracturing operations use extensive equipment and fuel, then the fracturing operations can be powered sufficiently, but the logistical complexity and environmental impact increase
Solution Approach 1:
The system divides the fracturing operation into modular components: a mobile power generation unit that can be independently positioned, a gas processing system, and fracturing equipment. This segmentation allows each component to be optimized and deployed separately, reducing overall logistical complexity while maintaining sufficient power supply capability.
Solution Approach 2:
The system uses hydrocarbon gas from the wellsite itself to generate electricity through a gas turbine, making the operation self-powered. This eliminates the need for external fuel supply chains and reduces logistical complexity by using the wellsite's own resources to power the fracturing operations.
2Productivity
If traditional fracturing operations use large volumes of fracturing fluid, then the fracturing process can be effective, but the environmental impact and resource consumption increase
Solution Approach 1:
The system changes the parameters of the fracturing operation by using compressed hydrocarbon gas instead of traditional water-based fracturing fluid. This parameter change maintains the effectiveness of the fracturing process while significantly reducing fluid volume and environmental impact.
3Quantity of substance
If the system compresses hydrocarbon gas for storage, then the gas can be stored at higher pressure, but the compression process requires additional energy
Solution Approach 1:
The system continuously compresses and stores hydrocarbon gas during operation, maintaining a steady state where the compression process is integrated into the overall gas handling workflow. This continuous operation eliminates idle time and ensures that compression energy is always being utilized productively, reducing the relative energy cost.
Solution Approach 2:
The compression system is powered by the same hydrocarbon gas that is being compressed and stored, creating a self-sustaining cycle. The gas turbine generates electricity from the hydrocarbon gas, which then powers the compressors, eliminating the need for external energy input and reducing the net energy consumption.
