Downhole Tool Deployment Apparatus with Actuation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current method of installing multiple downhole tools in a wellbore is time-consuming and costly due to the need to repeatedly pull conveyance out of the hole between each tool installation.
Innovation Solution
A downhole deployment apparatus that houses multiple tools and uses an actuation mechanism, such as a continuous screw or inner housing with a J-slot mechanism, to selectively eject tools at desired locations along the wellbore, allowing for self-anchoring or self-sealing, reducing the need for frequent conveyance retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple downhole tools are installed by repeatedly pulling conveyance out of hole, then each tool can be individually installed, but operational time and cost increase significantly
Solution Approach 1:
The conveyance is segmented into a housing apparatus that can be independently deployed and retrieved, separating the tool deployment function from the conveyance retrieval function. This allows multiple tools to be deployed from a single housing apparatus without repeatedly pulling the entire conveyance out of the hole.
Solution Approach 2:
Multiple downhole tools are pre-loaded into the housing apparatus before deployment. The tools are arranged in sequence within the housing, allowing them to be deployed at different locations along the wellbore without retrieving the conveyance between installations.
2Reliability
If conveyance is pulled out of hole between each tool installation, then tools can be securely installed, but operational cost increases
Solution Approach 1:
The system separates the housing apparatus from the conveyance, allowing the housing to be retrieved and reused while leaving the conveyance in place. This segmentation eliminates the need to pull the entire conveyance out of the hole for each tool installation, reducing operational costs.
Solution Approach 2:
The housing apparatus is designed to be retrieved and reused for subsequent tool deployments, while the conveyance remains in the wellbore. This recovering approach eliminates repeated conveyance retrieval operations, reducing energy consumption and operational costs.
3Productivity
If a single conveyance is used for multiple tools, then operational efficiency improves, but tool deployment precision becomes difficult to control
Solution Approach 1:
The actuation mechanism includes a movable piston that can be positioned at different locations within the housing apparatus. This dynamic positioning allows precise control over where each tool is deployed along the wellbore, maintaining deployment precision while improving operational efficiency.
Solution Approach 2:
The system incorporates positioning control through the piston mechanism that responds to predetermined locations marked in the wellbore. This feedback mechanism ensures accurate tool deployment at specified locations while maintaining high operational efficiency.
