Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current techniques for monitoring material flow in oil and gas wells lack the ability to provide valuable thermal information, as tracer agents like fluorescein do not indicate temperature conditions effectively.
Innovation Solution
Encapsulating tracer agents in thermally responsive shells that release the agent upon encountering specific temperatures, allowing for the determination of temperature conditions within well spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a tracer agent like fluorescein is injected into wells to monitor material flow, then flow direction information can be obtained, but thermal information regarding the environments below cannot be obtained
Solution Approach 1:
The patent combines a tracer agent (fluorescein) with a thermally responsive shell into a single encapsulated system. The shell contains the tracer agent and is designed to release it at specific temperature thresholds, enabling simultaneous monitoring of both flow direction (through tracer detection) and thermal conditions (through temperature-triggered release patterns), thereby merging flow tracking and temperature sensing capabilities into one versatile tool
Solution Approach 2:
The thermally responsive shell acts as an intermediary between the tracer agent and the environment. It controls the release of the tracer agent based on temperature conditions, using the shell material's thermal sensitivity as a mediator to translate temperature information into detectable release patterns, thus enabling indirect thermal measurement through tracer release behavior
2Loss of information
If a tracer agent is used to monitor material flow, then flow direction can be indicated, but the tracer does not yield valuable thermal information
Solution Approach 1:
The patent utilizes fluorescein, a tracer agent that exhibits fluorescence properties, to detect and indicate temperature conditions. When the thermally responsive shell releases the encapsulated fluorescein at specific temperature thresholds, the fluorescent signal provides a precise and detectable indicator of the temperature conditions encountered, enabling accurate thermal information retrieval through optical detection
Solution Approach 2:
The thermally responsive shell is designed to change its properties (such as solubility, permeability, or structural integrity) in response to temperature changes. This parameter change allows the shell to release the tracer agent at specific temperature thresholds, converting temperature information into a detectable release event that provides precise thermal measurement capability

AI summary
Systems and methods for releasing a material into an environment. The material may be encapsulated in a receptacle or otherwise packaged for movement into the environment. The receptacle with the material inside is introduced into the environment. A triggering causes release of the material from the receptacle into the environment.
