Sensor Deployment Shuttle for Wellbore Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Deploying conventional sensors for monitoring hydraulic fracturing and hydrocarbon production in well casings is costly, time-consuming, and complex due to the need for careful attachment and potential damage during insertion, and current systems are often permanently fixed, limiting their reuse and ability to collect downhole data effectively.
Innovation Solution
A sensor deployment system comprising a deployment shuttle with a sleeve and wire support that can be positioned within the well casing, allowing sensors to be inserted and removed while minimizing pressure loss and enabling continuous data collection during stimulation and production phases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sensors are attached to the well casing before insertion, then the sensors can be deployed in the wellbore, but the deployment process becomes costly, time-consuming, and complex with risk of damage to sensors or communication wire
Solution Approach 1:
The system divides the sensor deployment process into separate components: the sensor assembly and the deployment shuttle. The shuttle acts as a temporary carrier that simplifies insertion, then detaches to allow the sensor to remain in place. This segmentation eliminates the need for complex pre-attachment procedures and reduces deployment complexity while maintaining reliability.
Solution Approach 2:
The deployment shuttle serves as an intermediary device between the surface deployment mechanism and the downhole sensor. It provides a protected interface during insertion, then releases the sensor to remain in place. This intermediary approach simplifies the overall deployment process while ensuring sensor integrity during the critical insertion phase.
2Reliability
If sensors are permanently fixed to the casing wall, then the sensors remain in position during production, but they cannot be removed for reuse or subsequent operations
Solution Approach 1:
The system transitions from a static permanent fixation approach to a dynamic deployment mechanism. The deployment shuttle provides temporary positioning during insertion, then releases the sensor assembly. This dynamic approach allows the sensor to remain stable during production while enabling removal and reuse for subsequent operations or different wells.
Solution Approach 2:
The deployment shuttle is discarded after serving its purpose of inserting the sensor, while the sensor assembly is recovered and can be reused. This principle allows the system to achieve stable positioning during production while maintaining adaptability for future operations, resolving the contradiction between permanent fixation and reuse capability.
3Loss of information
If sensors are deployed during well completion, then downhole data can be collected, but the deployment process requires careful coordination to avoid damaging sensors during perforation operations
Solution Approach 1:
The sensor assembly is pre-positioned within the deployment shuttle before perforation operations begin. The shuttle provides protective positioning that shields the sensor from damage during the perforation process. This preliminary action ensures data collection capability is established while minimizing exposure to harmful factors during the critical perforation phase.
