Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current methods for determining extraction efficiency are used, then extraction efficiency can be determined, but the procedure is complex and results are unreliable
Solution Approach 1:
The method applies preliminary action by first spiking the drilling mud with a known quantity of volatile species and allowing equilibrium to be established before extraction. This preliminary preparation creates a controlled initial condition that simplifies subsequent extraction efficiency calculation, avoiding the complexity of trying to measure unknown concentrations directly.
Solution Approach 2:
The invention creates a simplified model system by spiking drilling mud with known quantities of volatile species, effectively creating a copy or representation of the actual extraction process under controlled conditions. This allows extraction efficiency to be determined in a simplified manner that can then be applied to actual drilling mud analysis.
2Measurement precision
If multiple extraction stages are performed as in prior art, then extraction efficiency can be calculated, but the procedure becomes time-consuming and complex
Solution Approach 1:
The method uses partial action by performing only a single extraction stage rather than multiple stages. The spiked known quantity of volatile species provides sufficient information to calculate extraction efficiency in one extraction, eliminating the need for time-consuming multiple extraction stages while maintaining accuracy.
Solution Approach 2:
The invention changes the parameter of volatile species concentration from unknown to known by spiking the drilling mud with a measured quantity. This parameter change allows extraction efficiency to be determined accurately in a single extraction stage, reducing the time required compared to methods requiring multiple stages.
3Ease of operation
If extraction efficiency is determined without spiking, then the procedure is simpler, but the results lack accuracy and reliability
Solution Approach 1:
The method applies preliminary action by spiking the drilling mud with a known quantity of volatile species before extraction. This preliminary step of adding a measured amount simplifies the calculation of extraction efficiency while simultaneously improving the accuracy and reliability of the results, avoiding the need for complex iterative procedures.
