Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual sampling and analysis of drill cuttings is performed, then analysis can be conducted, but it results in partial understanding of subsurface materials at high cost and time consumption
Solution Approach 1:
The patent replaces manual mechanical sampling and analysis with an automated system featuring a shaker table, sensors (gamma ray, sonic, resistivity, density), and digital imaging technology. This substitution enables continuous real-time analysis of drill cuttings, eliminating the time-consuming manual processes while improving the precision and completeness of subsurface material characterization
Solution Approach 2:
The system enables self-service analysis where the drill cuttings automatically pass through the analysis module, are shaken to separate fluids, and are analyzed by sensors and cameras without requiring manual intervention. The system continuously monitors and records data, providing complete subsurface material understanding autonomously
2Productivity
If real-time analysis of drill cuttings is implemented, then continuous monitoring is achieved, but device complexity increases
Solution Approach 1:
The analysis module integrates multiple functions into a single device: the shaker table separates fluids from cuttings, multiple sensors (gamma ray, sonic, resistivity, density) simultaneously measure different properties, and a camera captures digital images. This multi-functional integration enables continuous real-time monitoring while consolidating what would otherwise require separate equipment
Solution Approach 2:
The patent combines the shaker table, sensor array, camera system, and data processing unit into an integrated analysis module that processes drill cuttings continuously. By merging these components into one unified system, the patent achieves continuous monitoring capability while managing device complexity through integration rather than proliferation of separate systems

AI summary
A shale shaker system. The system includes a fluid transport pipe configured to receive a stream of drill cuttings and fluid returns from a wellbore during a drilling operation; an analysis module configured to receive at least a portion of the stream of drill cuttings and fluid returns at an inlet; a cuttings chute configured to receive at least a portion of the stream of drill cuttings and fluid returns from an outlet of the container, and deliver them to a screen box; and one or more screens for filtering drill cuttings from the fluid returns. The analysis module comprises logging sensors configured to operate while drill cuttings are moving through the system. The logging sensors communicate with a processor to determine characteristics of the drill cuttings in real time. A method for analyzing drill cuttings at a well site is also provided.
