The system is designed for operation by drilling team members and can provide autonomous, repeatable, and location-identified sample data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If core samples are shipped to a distant laboratory for analysis, then analysis can be performed with controlled environment and trained personnel, but sample transport time and overall analysis time increase significantly
Solution Approach 1:
The patent creates a portable copy of the laboratory analysis capability by deploying an XRF analysis system that can be positioned at the drilling site. This mobile system replicates the analytical functions of a fixed laboratory, eliminating the need to transport samples while maintaining analysis quality through standardized measurement procedures and calibrated instrumentation.
Solution Approach 2:
The patent transitions the analysis capability from a centralized fixed-location laboratory to a distributed mobile platform that can move between drilling sites. This dimensional shift from static to mobile deployment allows analysis to occur in the field, fundamentally changing the spatial organization of the analysis workflow and eliminating transport time.
2Productivity
If portable core analysis systems are used, then analysis time is reduced and integration with drilling workflow is improved, but measurement precision and data reliability deteriorate
Solution Approach 1:
The patent implements comprehensive parameter control and calibration procedures for the portable XRF system. This includes establishing standardized measurement parameters, implementing calibration protocols using reference materials, and controlling environmental parameters that could affect measurement accuracy. These parameter changes ensure that the portable system produces data with precision comparable to fixed laboratory systems.
Solution Approach 2:
The patent incorporates quality control measures and validation procedures that provide feedback on measurement accuracy. This includes using certified reference materials to verify system performance, implementing data quality checks, and establishing protocols for detecting and correcting measurement errors. The feedback mechanisms ensure that high-speed portable analysis maintains data reliability.
3Ease of operation
If existing portable core analysis systems are used, then mobility and workflow integration are improved, but measurement repeatability and location consistency deteriorate
Solution Approach 1:
The patent implements preliminary positioning and setup procedures that establish consistent measurement locations before analysis begins. This includes using GPS or other positioning systems to identify and mark specific sampling locations on the core, and establishing standardized positioning fixtures or guides that ensure repeatable placement of the XRF probe. These preliminary actions guarantee that subsequent measurements are taken from consistent locations, enabling reliable comparison of results.
