Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current activation devices for downhole tools in wellbore operations are costly, time-consuming, and often require unique devices for each tool, with power-dependent methods posing environmental risks.
Innovation Solution
A single activation device using a combination of magnetic fields and physical engagement to activate multiple downhole tools, where the magnetic field is generated by permanent magnets or electromagnetically, allowing for flexible control of downhole tools without the need for multiple devices or power sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple unique activation devices are used for each downhole tool, then each tool can be reliably activated, but the cost and time for operations increase significantly
Solution Approach 1:
A single activation device is designed to activate multiple different downhole tools (packers, valves, flow control devices) through a unified activation mechanism, eliminating the need for multiple unique activation devices while maintaining reliable activation of each tool type
Solution Approach 2:
The patent combines multiple activation functions into one device that can interact with various downhole tools sequentially, merging what would traditionally require separate devices into a single integrated activation system
2Ease of operation
If power-dependent activation methods are used, then precise control is achieved, but environmental risks and operational complexity increase
Solution Approach 1:
The patent replaces power-dependent electronic control systems with a mechanical activation mechanism that uses physical interaction (ball seating, spring compression) to activate downhole tools, eliminating the need for power sources and reducing environmental risks associated with battery disposal in harsh wellbore environments
3Productivity
If a single activation device is used for multiple tools, then cost and operation time are reduced, but the device complexity increases
Solution Approach 1:
The activation device is designed with modular components including separate interaction mechanisms for different tool types, allowing it to handle multiple tools through segmented functional sections rather than a monolithic complex design
Solution Approach 2:
The patent uses intermediary elements such as balls, springs, and mechanical linkages that mediate between the single activation device and multiple downhole tools, simplifying the interaction mechanism while enabling activation of various tool types

AI summary
An activation device is disclosed that can activate multiple downhole tools in a wellbore. The activation device is cost effective and easy to produce. A method for activating multiple downhole tools in a wellbore is described where at least one downhole tool is activated by magnetic field, while at least one additional downhole tool is activated by mating of the activation device with the downhole tool.
