Remote Wellhead Sensors for Continuous Operation Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing well operation analysis is limited by rig-specific data, which cannot provide comprehensive information for analyzing operations beyond rig state and is restricted to data captured during rig presence and operation.
Innovation Solution
A system utilizing remote sensors located independently of the well rig to generate and analyze data on operating characteristics, including pressure, temperature, and proximity sensors, enabling analysis of well operations such as drilling, completion, and production, even when the rig is not present or operational.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If rig-specific data is used for well operation analysis, then rig state identification is achieved, but comprehensive well operation analysis is limited
Solution Approach 1:
The system divides the sensing function into two independent segments: rig-mounted sensors for rig state monitoring and wellhead-mounted remote sensors for well operation monitoring. This segmentation allows each sensor system to focus on its specific function, enabling comprehensive well operation analysis without requiring complex integration of multiple sensing systems.
Solution Approach 2:
The remote sensor system acts as an intermediary between the well and the analysis system, providing direct measurements of well operating characteristics without relying on rig-specific data. This intermediary sensing system bridges the information gap for comprehensive well operation analysis.
2Duration of action of stationary object
If rig-specific data is used for well operation analysis, then data acquisition during rig operation is possible, but analysis capability when rig is absent is lost
Solution Approach 1:
The sensing system is segmented into rig-mounted and wellhead-mounted components. The wellhead-mounted remote sensors remain permanently installed at the well, enabling continuous monitoring of well operating characteristics regardless of rig presence or movement to different wells.
Solution Approach 2:
The system implements more sensing capability than traditionally required by placing sensors both on the rig and at the wellhead. This excessive action ensures that well operation data is captured even when the rig is absent, providing redundant coverage that extends monitoring duration beyond rig operational periods.
Data Source
AI summary
Sensors may be located remotely from a rig of a well. The sensors may operate independently of the rig, and generate remote sensor information that characterizes operating characteristics of the well independent of the rig. The operation of the well may be analyzed based on the remote sensor information.
