Solution Overview
Problem
Current methods for assessing the repeatability and reliability of time series sensor data in borehole environments face challenges in accurately comparing data sets acquired during different periods, especially when physical phenomena remain constant, leading to inconsistencies and difficulties in operational decision-making.
Innovation Solution
A method involving the training of a regression model using initial and secondary sets of time series sensor data to transform and compare data, identifying variations and inconsistencies, thereby enhancing data reliability and operational control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If time series sensor data is acquired during different periods (first period and second period), then data coverage and operational insight are improved, but data consistency and repeatability deteriorate due to potential changes in physical phenomena or environmental conditions
Solution Approach 1:
The system transforms sensor data from different time periods into a common reference frame by adjusting parameters such as temperature, pressure, and other environmental conditions. This allows data from the first period and second period to be compared consistently despite changes in physical phenomena, resolving the contradiction between expanded data coverage and maintained repeatability
Solution Approach 2:
A transformation model acts as an intermediary between data from different time periods. This model mediates the comparison by normalizing and aligning data from the first period and second period, enabling reliable repeatability assessment while preserving the expanded temporal coverage provided by multi-period data acquisition
2Ease of operation
If sensor data is compared directly without transformation, then analysis simplicity is maintained, but measurement precision deteriorates due to inconsistencies in data from different time periods
Solution Approach 1:
The system performs preliminary transformation of sensor data from the first period into a common reference frame before comparison with second period data. This preliminary action prepares the data in advance, ensuring that when direct comparison is made, both datasets are in consistent units and conditions, thereby maintaining ease of operation while achieving high measurement precision
3Reliability
If regression models are trained to transform data, then data reliability is improved, but computational complexity and processing time increase
Solution Approach 1:
Instead of working with the original complex multi-period data directly, the system creates transformed copies of the data in a common reference frame. These transformed copies preserve the essential relationships and patterns while simplifying the data structure for analysis, thereby improving reliability without proportionally increasing computational complexity
Solution Approach 2:
The regression model transforms data by changing parameters such as temperature, pressure, and other environmental conditions to a standardized reference state. This parameter transformation simplifies the data representation and reduces computational complexity while maintaining data consistency and reliability across different time periods

AI summary
A method can include receiving a first set of time series sensor data of a region and a second set of time series sensor data of the region; training a regression model using the first set and the second set to generate a trained regression model; transforming at least a portion of the first set to a comparison space, using the trained regression model, to generate a comparison set; and comparing at least a portion of the second set to the comparison set to determine variation between the first set and the second set with respect to the region.
