Flexible Interconnect Wellbore Tool Deployment Pressure Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for deploying tools in wellbores face challenges in maintaining pressure containment and sealing during the deployment of multiple tools, particularly in pressurized environments, which limits the depth and area that can be monitored effectively.
Innovation Solution
A system that uses a pressure-containment device with an actuable sealer and a tool trap, coupled with flexible interconnects and clamps, to isolate and maintain pressure within the wellbore, allowing tools to be deployed in predetermined increments without requiring rigid tubing, thereby enabling deeper and wider monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigid tubing is used to maintain pressure containment during tool deployment, then pressure containment is maintained, but device complexity and deployment difficulty increase
Solution Approach 1:
The patent employs a flexible interconnect (wireline) instead of rigid tubing to maintain pressure containment during tool deployment. The flexible interconnect passes through a pressure containment device with seals that maintain pressure isolation while allowing the flexible line to move and deploy tools. This resolves the contradiction by providing pressure containment without the complexity of rigid tubing systems.
Solution Approach 2:
The pressure containment device acts as an intermediary between the pressurized wellbore environment and the tool deployment system. It contains the pressure while allowing the flexible interconnect to pass through and deploy tools, mediating between the conflicting requirements of pressure containment and flexible deployment.
2Length of moving object
If tools are deployed in pressurized wellbores using traditional methods, then deployment is possible, but the depth and area that can be monitored are limited
Solution Approach 1:
The flexible interconnect enables tool deployment to greater depths in pressurized wellbores by eliminating the constraints of rigid tubing. The flexible nature allows the system to navigate deeper wellbores and monitor larger areas while maintaining pressure containment through the pressure containment device and seals.
Solution Approach 2:
The system transitions from static rigid tubing to a dynamic flexible interconnect that can be deployed incrementally. Tools are deployed in predetermined increments by lowering them on the flexible interconnect, allowing the system to adapt to varying depths and conditions while maintaining ease of operation.
3Area of stationary object
If multiple tools are deployed in predetermined increments, then monitoring coverage increases, but the sealing and pressure containment become more difficult
Solution Approach 1:
The system segments the tool deployment into multiple tools deployed in predetermined increments along the flexible interconnect. Each tool can be positioned at specific depths, and the pressure containment device maintains sealing reliability for each deployment segment, allowing expanded monitoring coverage without compromising seal integrity.
Solution Approach 2:
The pressure containment device serves as an intermediary that maintains reliable sealing while multiple tools are deployed on the flexible interconnect. It isolates the pressurized environment from the tool deployment operations, ensuring sealing reliability is maintained even as multiple tools are positioned at different depths.
