Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hydrocarbon recovery operations face challenges in detecting kicks, which can lead to blowouts due to the inability to effectively monitor and manage pressure differentials between formation pressure and drilling fluid hydrostatic pressure.
Innovation Solution
Implementing a power monitoring system for shakers that processes downhole particles, utilizing indicators such as power consumption, fluid flow, and vibration analysis to detect kicks and provide early warning systems for mitigating actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If power monitoring of shaker is implemented to detect kicks, then detection reliability is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical pressure monitoring systems with an electrical power monitoring system. By measuring the electrical power consumption of the shaker motor, the system indirectly detects kick conditions without requiring direct mechanical sensors in the wellbore, thus improving reliability while reducing device complexity
Solution Approach 2:
The patent introduces electrical power consumption as an intermediary parameter to detect kick conditions. Instead of directly measuring formation pressure or fluid influx, the system uses power monitoring as a mediator that reflects changes in downhole conditions through the shaker's electrical load, simplifying the detection mechanism while maintaining reliability
2Measurement precision
If multiple indicators (power, fluid flow, vibration) are monitored to detect kicks, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple monitoring functions (power monitoring, fluid flow monitoring, vibration monitoring) into a single integrated kick detection system. By merging these indicators and analyzing them collectively, the system achieves high measurement precision for kick detection without proportionally increasing device complexity, as the components share common processing and control infrastructure
Solution Approach 2:
The monitoring system is designed with multi-functionality, where a single system performs multiple detection tasks using different indicators. The power monitoring system, fluid flow system, and vibration system work together as a universal kick detection platform, reducing overall complexity compared to separate specialized systems for each indicator

Data Source
AI summary
A method includes performing a downhole operation in a borehole in a formation. Downhole particles and drilling mud are captured at a surface from the borehole into a screen of a shaker during the downhole operation. Input power that comprises at least one of voltage, current, and leakage current being supplied to the shaker is monitored during operation of the shaker, it is determined whether the input power exceeds a threshold as a result of change in a load on the shaker. In response to determining that the input power exceeds the threshold as the result of change in the load on the shaker, it is determined that there is a kick condition in the borehole, where the kick condition comprises a condition in which a pressure of the formation exceeds a pressure in the borehole.
