Smart Jarring System Laser Feedback for Stuck Pipe
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional jarring systems lack real-time feedback on downhole conditions and jarring results, making it difficult to determine if the jars have activated and which direction they have fired, which can lead to costly and detrimental stuck pipe scenarios.
Innovation Solution
A smart jarring system that includes a set of jars equipped with a laser source and receiver to provide real-time data on jarring operations, along with sensors such as vibration, temperature, and torque/tensile sensors to diagnose downhole conditions and determine corrective steps for freeing stuck equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional jarring systems are used, then the structure is simple and easy to manufacture, but real-time feedback on downhole conditions and jarring results is not provided
Solution Approach 1:
The patent implements feedback by installing laser sources and receivers within the jarring system to detect and transmit real-time information about jar activation and downhole conditions back to the surface, eliminating the information loss present in conventional systems
Solution Approach 2:
The jarring system is enhanced with multiple functions by integrating laser detection capabilities, vibration sensing, temperature monitoring, and torque measurement into a single unified system that performs both jarring and diagnostic functions
2Measurement precision
If conventional jarring systems are used, then the device complexity is low, but it is difficult to determine if the jars have activated and in which direction they have fired
Solution Approach 1:
The patent replaces mechanical detection methods with optical laser-based detection systems that can precisely measure jar activation and direction without the complexity of complex mechanical linkages and indicators
Solution Approach 2:
Laser beams serve as intermediaries to transmit information about jar activation and direction from the downhole environment to the surface measurement system, enabling precise detection without direct mechanical connection
3Reliability
If real-time monitoring is implemented, then data-driven decision-making is enabled, but the device complexity increases
Solution Approach 1:
The system achieves enhanced reliability through multi-functional sensors that simultaneously monitor vibration, temperature, and torque conditions, providing comprehensive real-time data without requiring separate dedicated systems for each parameter
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables real-time monitoring and data-driven decision-making to effectively free stuck equipment by determining if and in which direction the jars have fired, optimizing jarring operations and reducing the risk of costly stuck pipe scenarios.
Implementation Method 1
The laser receiver intercepts a laser beam that is emitted from the laser source. This interception helps determine when the set of jars fired and in which direction the set of jars fired.
Data Source
AI summary
A smart jarring system for freeing stuck equipment downhole is disclosed. The smart jarring system comprises a set of jars, at least one laser source and at least one laser receiver that corresponds to the at least one laser source. The laser receiver intercepts a laser beam that is emitted from the laser source. This interception helps determine when the set of jars fired and in which direction the set of jars fired. The smart jarring system further comprises one or more sensors selected from the group consisting of vibration sensors, temperature sensors, and torque/tensile sensors. These sensors are configured to diagnose downhole conditions and help free the stuck equipment downhole.
