Solution Overview
Problem
Current well treatment systems lack the capability to simultaneously deploy fracturing equipment and sand control screen assemblies, which limits the efficiency of multi-stage well stimulation and production operations, particularly in managing fluid flow and isolating specific well sections.
Innovation Solution
A well system comprising a multi-stage treatment system with isolation devices and flow valves for fracturing, combined with sand control screen assemblies equipped with isolation valves, allowing for simultaneous treatment and production operations by isolating sections of the wellbore and controlling fluid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate procedures are used for fracturing and sand control deployment, then each function can be performed with dedicated equipment, but the overall operational efficiency is reduced due to sequential operations
Solution Approach 1:
The patent combines fracturing equipment and sand control screen assemblies into a single integrated well system that can be deployed simultaneously. The system integrates multi-stage fracturing capabilities with sand control functions through a unified tubular structure, eliminating the need for separate deployment procedures and improving operational efficiency.
Solution Approach 2:
The well system performs multiple functions simultaneously - it conducts multi-stage fracturing operations while also providing sand control through integrated screen assemblies. The system is designed to handle both treatment and production functions within a single deployment, reducing the number of separate operations required.
2Productivity
If simultaneous deployment of fracturing equipment and screen assemblies is implemented, then operational efficiency improves, but the device complexity increases
Solution Approach 1:
The well system is divided into multiple discrete stages, with each stage containing its own fracturing equipment and screen assembly. This segmentation allows for independent control and operation of each stage while maintaining overall system integration. The modular design facilitates simultaneous deployment across multiple stages without excessive complexity.
Solution Approach 2:
The system employs a nested structure where screen assemblies are positioned within the tubular structure of the multi-stage treatment system. The screen assemblies are integrated into the existing fracturing system architecture, allowing one component to be placed within another without creating excessive structural complexity.
3Ease of operation
If isolation devices and flow valves are integrated into each screen assembly, then selective flow management is improved, but the manufacturing complexity increases
Solution Approach 1:
Isolation devices and flow valves are pre-integrated into each screen assembly during manufacturing. This preliminary integration ensures that flow control capabilities are built into the basic structure of each assembly, allowing for selective flow management during operation without requiring complex field assembly procedures.
