Running Tool System for Tubing Hanger Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wellhead systems require multiple tools and complex operations to deploy and secure tubing hangers, which increases operational complexity and costs.
Innovation Solution
A running tool system that includes a first sleeve for axial movement and a second sleeve for rotational locking, allowing the running tool to both lower and set a tubing hanger without a separate sleeve, thereby simplifying the deployment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wellhead systems use multiple tools and complex operations to deploy and secure tubing hangers, then the hanger can be securely locked in position, but the operational complexity and time increase
Solution Approach 1:
The patent combines the functions of multiple separate tools (running tool for axial movement and separate sleeve for rotational locking) into a single integrated running tool system. The first sleeve provides axial movement while the second sleeve provides rotational locking, merging previously separate operations into one tool that performs both functions sequentially
Solution Approach 2:
The running tool is designed with universal functionality to perform multiple operations: axial movement via the first sleeve and rotational locking via the second sleeve. This multi-functional design eliminates the need for separate specialized tools, reducing operational complexity while maintaining reliable hanger securing
2Productivity
If conventional systems use multiple separate tools for hanger deployment, then each tool can be optimized for its specific function, but the operational time and costs increase
Solution Approach 1:
By merging the axial movement function (first sleeve) and rotational locking function (second sleeve) into a single running tool, the system enables both operations to be performed in one continuous sequence without tool changes or interruptions, significantly reducing operational time and improving deployment efficiency
Solution Approach 2:
The running tool is pre-configured with both the first sleeve for axial movement and the second sleeve for rotational locking, allowing all necessary operations to be prepared in advance and executed in a single trip, eliminating the need for subsequent intervention operations

AI summary
A technique facilitates utilization of a running tool system for use with a tubing hanger deployed at a wellhead. The running tool system may comprise a running tool which may be coupled to a hanger. The running tool may include a first sleeve which may be coupled to the hanger for moving the hanger in an axial direction. According to an embodiment, the running tool also may include a second sleeve which may be coupled to an adjustable landing ring disposed about the hanger. The second sleeve may be used to rotate the adjustable landing ring so as to lock the hanger in position.
