Multiple Offset Slim Connector for Wellhead Conductor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mineral extraction systems face space and cost challenges due to the need for multiple wellhead assemblies, which can be mitigated by connecting multiple wellheads within a single conductor to share redundant components and reduce spatial requirements.
Innovation Solution
The implementation of a multiple offset slim connector system that allows for the efficient spatial configuration of multiple wellheads within a single conductor, utilizing a CSW adapter system with a common body lock ring, multiple offset slim connector, hold down ring, and union ring to minimize space usage and share components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate wellhead assemblies are used, then each wellhead can be independently operated and maintained, but the spatial requirements and cost increase significantly
Solution Approach 1:
The patent combines multiple wellhead assemblies into a single integrated wellhead structure with multiple independent boreholes, allowing multiple wells to be accessed through one shared wellhead assembly rather than requiring separate assemblies for each well
Solution Approach 2:
The wellhead assembly is designed with multi-functionality to serve multiple wells simultaneously, featuring multiple independent boreholes and associated components that can be independently operated while sharing common structural elements
2Reliability
If multiple separate wellhead assemblies are used, then each well can have dedicated components, but the overall system cost increases due to redundancy
Solution Approach 1:
The patent merges multiple wellhead assemblies into one integrated structure where common components such as the main body, flanges, and support structures are shared across multiple boreholes, reducing the total number of redundant components
Solution Approach 2:
The wellhead assembly incorporates universal components that serve multiple functions across different boreholes, allowing a single component to support multiple wells while maintaining the ability to independently control and maintain each well
3Ease of manufacture
If multiple separate wellhead assemblies are used, then installation is straightforward, but the spatial footprint and material usage increase
Solution Approach 1:
The patent combines multiple wellhead assemblies into a single integrated structure that uses shared materials and components, significantly reducing the total quantity of steel, concrete, and other materials required compared to installing separate wellhead assemblies for each well

AI summary
A system, in certain embodiments, includes a wellhead connector configured to connect with multiple wellheads within a single wellhead conductor. The system may also include a hold down ring configured to be positioned radially around the wellhead connector and to lock the wellhead connector in position axially on top of the multiple wellheads by applying an axially downward force onto the wellhead connector. In addition, the system may include a body lock ring configured to be positioned radially around the multiple wellheads. The system may also include a union ring configured to be positioned radially around both the hold down ring and the body lock ring and to lock the hold down ring and the body lock ring in position adjacent each other axially.
