Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sensors for wellbore fluid analysis are limited by their operational energy ranges, which can lead to incomplete detection of analytes due to interference from other components, particularly in the visible, near-infrared, and mid-infrared wavelength ranges, and pose safety risks with high energy usage.
Innovation Solution
A system utilizing a contrast device with a mesoporous substrate and a contrast agent that interacts with analytes to alter detectable properties, allowing for enhanced detection by sensors, including optical, acoustic, NMR, and dielectric systems, by facilitating contact between the contrast agent and analyte within the wellbore fluid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If high energy ranges are used to increase the spectrum of detectable components, then the detection capability is improved, but safety risks increase and sensor repair/replacement frequency increases
Solution Approach 1:
The patent introduces a contrast agent as an intermediary substance that interacts with the analyte to produce a detectable signal. This mediator enables detection of components that would otherwise require high energy ranges, allowing optical sensors to detect a broader spectrum of analytes (including those not active in visible, near-infrared, or mid-infrared ranges) without using dangerous high energy radiation. The contrast agent converts the interaction into a form detectable by conventional optical sensors.
2Adaptability or versatility
If high energy ranges are used to increase the spectrum of detectable components, then the detection capability is improved, but sensor repair/replacement frequency increases
Solution Approach 1:
The contrast agent serves as a mediator that enables broad-spectrum detection using low-energy optical radiation. By having the contrast agent interact with various analytes to produce detectable optical signals, the sensor can maintain high adaptability across different components without exposing the sensor itself to damaging high energy ranges, thereby improving reliability and reducing repair/replacement frequency.
Solution Approach 2:
The patent changes the detection parameter by introducing a chemical interaction layer (the contrast agent) that translates analyte properties into optical signals. This parameter change allows the sensor to detect components across a broad spectrum by measuring the optical properties of the contrast agent-analyte complex rather than directly detecting the analyte, thus avoiding the need for high energy ranges that would damage the sensor.
3Object-affected harmful factors
If conventional energy ranges are used for optical sensing, then safety is maintained, but detection of certain analytes is limited due to lack of activity or interference from other components
Solution Approach 1:
The contrast agent acts as an intermediary that enables detection of analytes inactive in conventional optical ranges. The contrast agent interacts with these analytes through chemical or physical interactions, producing a signal that is active in the visible, near-infrared, or mid-infrared ranges. This allows the sensor to detect a wider variety of components safely using low-energy optical radiation.
4Object-affected harmful factors
If conventional energy ranges are used for optical sensing, then safety is maintained, but detection sensitivity is reduced due to interference from other components
Solution Approach 1:
The contrast agent serves as a selective intermediary that enhances the detectability of specific analytes. By choosing contrast agents with specific interaction characteristics, the system can enhance the signal from the target analyte while the mesoporous substrate provides physical separation that reduces interference from other components. This improves measurement precision and detection sensitivity while maintaining safety with conventional energy ranges.
