One-Trip Wellhead Hanger Installation Tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing wellhead components are time-consuming and costly due to the need for multiple tool trips into the wellhead, with each tool performing only a single operation before being retrieved and replaced.
Innovation Solution
A one-trip tool that can run a wellhead component into the wellhead, engage internal couplings to lock it in place, over-pull to verify engagement, and cement the component within the wellhead, all in a single operation without requiring tool retrieval or replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate tools are used to perform different operations (running, locking, over-pulling, cementing), then each operation can be performed with a specialized tool, but the installation process becomes time-consuming and costly due to multiple tool trips
Solution Approach 1:
The patent combines multiple separate tools (running tool, locking tool, over-pull tool, cementing tool) into a single integrated one-trip tool. This tool can perform running, locking, over-pulling, and cementing operations sequentially without being retrieved from the wellhead, thereby reducing installation time while maintaining the reliability of each specialized function
Solution Approach 2:
The one-trip tool is designed as a multi-functional device that can perform multiple operations (running the hanger into the wellhead, engaging internal couplings to lock it, over-pulling to verify engagement, and cementing) within a single trip. This universality eliminates the need for multiple specialized tool trips, directly addressing the time loss issue
2Ease of manufacture
If multiple separate tools are used for different operations, then each tool can be optimized for its specific function, but the overall installation cost increases due to multiple tool trips and operations
Solution Approach 1:
The patent merges multiple specialized tools into one integrated tool that maintains the functional capabilities of each component tool. This allows the system to preserve ease of manufacture for each function while dramatically improving productivity by eliminating repeated tool trips and operations
3Loss of time
If a single integrated tool is used to perform multiple operations, then installation time and costs are reduced, but the tool complexity increases
Solution Approach 1:
The one-trip tool is designed with segmented, modular components that can be independently manufactured and assembled. This segmentation manages the inherent complexity by organizing the tool into distinct functional modules (running mechanism, locking mechanism, over-pull mechanism, cementing mechanism) while still achieving the benefit of performing multiple operations in a single trip

AI summary
There is provided a system and method for installing a wellhead component in a single trip. Generally, a wellhead component may be run into a wellhead using a running tool. The running tool may then be retrieved from the wellhead and replaced with a locking tool, which is also run into the wellhead. Additional tools may be used to over-pull the wellhead component and to cementing the wellhead component in place. The process of retrieving and running tools into the wellhead is both time-consuming and costly. Accordingly, the disclosed embodiments include a one-trip tool configured to run a wellhead component into a wellhead, engage an internal coupling to lock the wellhead component in place, over-pull the wellhead component to ensure the internal coupling was properly engaged, and cement the wellhead component in place within the wellhead.
