Integrated Flow Meter in Production Tree Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current completion systems for subterranean resource extraction lack efficient methods for measuring production flow, particularly in subsea environments, where traditional flow meters may not be effectively integrated with existing wellhead and production tree configurations without disrupting operations.
Innovation Solution
Incorporating a flow meter with differential pressure measurement capabilities, such as a venturi tube, and fraction measurement systems like multi-energy gamma densitometry within the production tree's wing bore, allowing for continuous flow measurement without altering the integration of the flow measurement in the wing bore, and including a choke valve in series with the flow meter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a flow meter is placed in the process flow line between the wellhead and commingling point, then production flow measurement is enabled, but the device complexity and overall size of the production assembly increases
Solution Approach 1:
The flow meter is integrated directly into the production tree assembly, merging the measurement function with the existing production infrastructure. This eliminates the need for separate external flow meter installations and reduces overall system complexity while maintaining measurement capability.
Solution Approach 2:
The production tree is designed to serve multiple functions simultaneously: it acts as both the production control structure and the flow measurement device. The flow meter becomes a multi-functional component that is part of the production tree, reducing the need for additional dedicated measurement equipment.
2Measurement precision
If traditional flow meters are used in subsea environments, then flow measurement is possible, but the integration with existing wellhead and production tree configurations is disrupted
Solution Approach 1:
The flow meter is merged with the production tree structure, creating an integrated assembly that adapts to subsea environments. This integration allows the measurement device to work seamlessly with existing wellhead and production tree configurations without requiring separate installation systems.
3Adaptability or versatility
If multiple components are included in the production assembly, then functional capabilities are enhanced, but the overall size and design complexity increases
Solution Approach 1:
Multiple functional components (flow meter, valves, and production tree elements) are merged into a single integrated assembly. This consolidation reduces the overall volume by eliminating the need for separate mounting structures and interconnections that would be required if these components were installed as separate units.
Solution Approach 2:
The flow meter and other components are nested within the production tree structure, with components arranged concentrically or in space-efficient configurations. This nesting approach maximizes functional capabilities while minimizing the external dimensions of the overall assembly.
