Radiused ID Baffle for Wellbore Tool Ejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wellbore servicing systems require high forces to deactivate tools equipped with spherical obturators, making them inefficient and costly to operate.
Innovation Solution
A wellbore servicing tool with a baffle featuring a seat contoured to match the spherical zone of an obturator, reducing the ejection pressure needed to disengage the obturator from the baffle to less than 800 psi, thereby lowering the operational force required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spherical obturator is used to activate and deactivate wellbore servicing tools, then the tool can be controlled to activate and deactivate functions, but the force required to move the ball is high
Solution Approach 1:
The baffle seat is contoured to match the spherical zone of the obturator, creating a curved seating surface that reduces the force required to eject the ball. The spherical geometry allows the ball to be lifted and redirected with less force compared to a flat or sharp-edged seat, resolving the contradiction between reliable tool control and high ejection force requirements
