Pre-assembled Borehole Conductor Assembly for Rapid Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The energy industry faces inefficiencies and cost disadvantages due to the need for multiple field connections when deploying sensor devices and logging tools in boreholes, which increases time and reduces performance during operations like drilling, stimulation, and production.
Innovation Solution
A borehole monitoring system with a conductor assembly featuring pre-connected wireless communication devices along a length of conductor, supported by a deployment device such as a spool, allows for the efficient deployment of these devices directly into the borehole, eliminating the need for field connections by attaching them at pre-selected locations before deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple field connections are performed at the borehole site to deploy sensor devices and logging tools, then the monitoring system can be deployed in the borehole, but the deployment time increases and operational efficiency decreases
Solution Approach 1:
The conductor assembly is pre-assembled with communication devices connected along its length in a controlled environment before deployment. This preliminary assembly eliminates the need for time-consuming field connections at the borehole site, directly resolving the contradiction by preparing the monitoring system components in advance for rapid deployment.
Solution Approach 2:
The monitoring system is divided into modular communication devices that are pre-connected along the conductor assembly. This segmentation allows the system to be manufactured and tested as discrete units before being deployed as an integrated assembly, improving deployment efficiency while reducing on-site connection time.
2Ease of operation
If field connections are made during deployment, then the communication devices can be installed in the borehole, but the complexity of field operations increases and performance is reduced
Solution Approach 1:
All connections between communication devices and the conductor are established in advance in a controlled manufacturing environment. This preliminary action transfers the complexity from the field deployment phase to the manufacturing phase, making field operations simpler and more straightforward while maintaining the same level of connection reliability.
Solution Approach 2:
The conductor assembly serves as an intermediary that pre-integrates multiple communication devices into a single deployable unit. This intermediary structure eliminates the need for complex field connections by providing a pre-assembled system that can be deployed as a complete package, reducing operational complexity.
