Wellbore Sleeve System Sequential Activation via Delay Restrictors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wellbore servicing systems face challenges in efficiently treating multiple zones due to increased working pressure required to activate additional tools, which complicates the activation of multiple tools using a single obturator, leading to difficulties in fluid communication and pressure management.
Innovation Solution
A wellbore servicing system comprising a first and second sleeve system with restrictors that are selectively unlocked by an obturator, allowing for a delayed mode of operation where fluid flow is controlled, enabling the system to transition from an installation mode to a fully open mode while maintaining pressure and preventing premature fluid loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple tools are activated by a single obturator, then the ability to treat multiple zones is improved, but the working pressure required to activate additional tools increases
Solution Approach 1:
The system segments the activation process by introducing delay systems (restrictors) that control the timing of each tool's activation. This allows the obturator to trigger multiple tools sequentially at different pressure levels, rather than requiring all tools to activate simultaneously at high pressure. Each zone treatment can be staged independently.
Solution Approach 2:
The delay systems are pre-configured with restrictors that control the rate of fluid communication establishment. This preliminary setup allows pressure to be managed in advance, enabling the obturator to pass through and trigger subsequent tools without encountering cumulative high pressure requirements.
2Adaptability or versatility
If fluid communication is established by activated tools, then the treatment capability is improved, but the working pressure required to activate additional tools increases
Solution Approach 1:
The system transitions from static simultaneous activation to dynamic sequential activation. Delay systems with可控 restrictors enable the fluid communication to be established at different rates and times for different tools, allowing pressure management to adapt to the specific activation stage and reducing peak pressure requirements.
3Productivity
If a single obturator is used to activate multiple tools, then the operational efficiency is improved, but the complexity of pressure management increases
Solution Approach 1:
The delay systems with restrictors provide self-regulating pressure management. Each restrictor automatically controls the pressure buildup and fluid communication rate for its associated tool based on pre-configured parameters, eliminating the need for complex external pressure control mechanisms and reducing operational complexity while maintaining efficiency.

AI summary
A wellbore servicing system, comprising a first sleeve system (200), the first sleeve system comprising a first sliding sleeve (260) at least partially carried within a first ported case (208), the first sleeve system being selectively restricted from movement relative to the first ported case by a first restrictor (284) while the first restrictor is enabled, and a first delay system configured to selectively restrict movement of the first sliding sleeve relative to the ported case while the restrictor is disabled.
