Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If offline laboratory analysis is used to monitor drilling fluid properties, then measurement precision can be achieved, but the analysis time is too long (hours to days) to enable real-time monitoring and proactive control
Solution Approach 1:
The patent replaces the mechanical/chemical laboratory analysis system with an optical detection system. Optical sensors and computing devices analyze drilling fluid properties through light interaction, providing real-time data without the time-consuming physical sample extraction and laboratory processing required by traditional methods
Solution Approach 2:
The patent introduces optical computing devices as intermediaries between the drilling fluid and the monitoring system. These devices use light as a mediator to interact with the drilling fluid and extract compositional information, enabling real-time monitoring without direct physical contact or sample removal
2Measurement precision
If offline sample extraction is performed for analysis, then the drilling fluid can be analyzed in the laboratory, but the sample characteristics change during lag time making the analysis non-indicative of true fluid properties
Solution Approach 1:
The optical computing device acts as an intermediary that measures drilling fluid properties in-situ without removing samples. The light-based measurement occurs directly in the drilling fluid, eliminating the lag time between sample extraction and analysis that causes compositional changes and ensures the measurement reflects true fluid properties
Solution Approach 2:
The patent replaces the mechanical sample extraction and transportation system with an optical measurement system that remains in-place. This substitution eliminates the physical handling and transport of samples that cause compositional changes, providing reliable real-time measurements of actual drilling fluid properties
3Productivity
If real-time monitoring of drilling fluids is implemented, then proactive control and immediate corrective actions can be taken, but the device complexity increases with optical computing devices and sensors
Solution Approach 1:
The optical computing devices are designed to perform multiple functions: they detect various drilling fluid properties (composition, density, viscosity indicators), provide real-time monitoring, and enable proactive control. This multi-functionality reduces the need for multiple separate monitoring systems, thereby managing overall system complexity while maintaining high productivity
Solution Approach 2:
The monitoring system is designed to operate autonomously with real-time data processing and analysis capabilities built into the optical computing devices. The system self-regulates and provides immediate feedback without requiring constant human intervention or complex external processing infrastructure, balancing automation benefits with manageable complexity
