Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a two-tiered process of characterizing downhole samples is used, then sample characterization can be performed, but uncertainties and errors are introduced due to intermediary steps
Solution Approach 1:
The patent extracts and eliminates the intermediary characterization steps from the two-tiered process. By using optical signals to directly determine reservoir characteristics without intermediate sample analysis, the system removes the sources of uncertainty and error while maintaining the ability to perform comprehensive reservoir characterization.
Solution Approach 2:
The patent introduces optical signals as a direct mediator between the reservoir environment and the characterization system. This eliminates the need for physical sample extraction and intermediate laboratory analysis, allowing direct measurement of reservoir properties through optical property correlations stored in memory.
2Reliability
If optical signals are processed through intermediary characterization steps, then sample analysis can be performed, but the process becomes complex and error-prone
Solution Approach 1:
The patent extracts the essential measurement function directly from the complex two-tiered process. By using optical signals to directly probe reservoir characteristics and correlating them with pre-stored optical property data, the system achieves high reliability while simplifying the operational process to a single direct measurement step.
3Ease of operation
If direct optical signal analysis is used, then the characterization process is simplified, but adequate analysis of spatial and temporal features may be insufficient without intermediary steps
Solution Approach 1:
The patent adds the dimension of temporal analysis by continuously monitoring optical signals over time and space along the wellbore. This allows the simplified direct optical measurement method to capture both spatial distribution and temporal evolution of reservoir characteristics, maintaining measurement precision while preserving process simplicity.
