Fluid Injection System Mandrel Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for injecting scale inhibitors and fracturing fluids into oil and gas wells through the choke of a production tree reduce the choke's capacity for pressure management and require complex retrofitting processes, involving multiple steps and tools.
Innovation Solution
A fluid injection system that injects fluids directly into the mandrel of a production tree, providing a pathway from the mandrel to the production bore and tubing, with a streamlined installation process using a single trip to attach and connect all necessary components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If fluid is introduced through the choke of a production tree, then fluid injection into the well is achieved, but the choke's capacity for pressure management is reduced or eliminated
Solution Approach 1:
The invention divides the fluid injection function from the choke by introducing a separate landing module that connects to the mandrel. This segmentation allows the choke to maintain its pressure management function while the landing module handles fluid injection, resolving the contradiction between fluid injection capability and choke versatility.
Solution Approach 2:
The landing module acts as an intermediary component between the fluid supply line and the wellbore. It provides a dedicated interface for fluid injection through the mandrel without interfering with the choke's pressure management capabilities, thus preserving both functions simultaneously.
2Quantity of substance
If a special choke insert is used for fluid injection, then fluid delivery to the well is enabled, but the installation process becomes complicated requiring multiple steps
Solution Approach 1:
The invention combines the fluid delivery function with a dedicated landing module that integrates the choke insert, fluid supply line connection, and wellbore interface into a single unified component. This merging eliminates the need for multiple separate installation steps required by previous solutions.
Solution Approach 2:
The landing module is designed as a universal interface that can be installed once and provides both fluid injection capability and maintains compatibility with existing choke operations. This multi-functional design simplifies installation by eliminating the need for specialized retrofitting procedures.
3Quantity of substance
If a special choke insert with landing module is installed, then fluid injection is achieved, but multiple installation trips and tools are required
Solution Approach 1:
The invention merges the fluid supply line connection, choke insert, and landing module into a single integrated assembly that can be installed in one trip. This combination eliminates the need for multiple sequential installation operations and reduces the time required for implementing fluid injection capability.

AI summary
A system for injecting fluids into a well having a fluid supply line (22) that is connected to a mandrel (6) at the top of the production tree (2). The system is designed so that all components of the system are packaged together and run to the production tree (2) in one run. The production tree (2) is designed to provide a pathway for the fluid to travel from the mandrel (6) to the production bore (4) within the tree (2), and then into the production tubing of a well.
