Downhole Perforator Gun Bypass Tool for Single-Run Operations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional downhole tools with perforator guns are limited to only perforating formations and require separate runs for different operations, lacking the capability to perform multiple tasks like cleanout or drilling in a single run.
Innovation Solution
A downhole tool design incorporating a perforator gun portion, fluid directing apparatus, and a bypass passageway that allows fluid to flow around the perforator gun, enabling additional operations like cleanout and drilling during a single run by directing fluid through a motor section and allowing for subsequent perforation activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a perforator gun is positioned in the well for perforating formation, then the perforation function is achieved, but the tool cannot perform additional operations like cleanout or drilling in the same run
Solution Approach 1:
The downhole tool integrates multiple functions including a motor section for drilling/cleanout operations, a perforator gun portion for perforation, and a fluid directing apparatus that enables the tool to perform drilling, cleanout, and perforation operations in a single run, thereby achieving multi-functionality without requiring separate tools for each operation
Solution Approach 2:
The perforator gun portion is disposed within the housing of the downhole tool, nested inside the motor section and fluid directing apparatus. This nesting arrangement allows the perforator gun to be integrated within the larger multi-functional tool structure, enabling it to perform perforation while the outer structure handles drilling or cleanout operations
2Loss of time
If the perforator gun is removed after firing, then the perforation task is completed, but separate runs are required for additional operations increasing time and complexity
Solution Approach 1:
The tool is designed with the perforator gun portion already positioned and integrated within the housing before deployment. The fluid directing apparatus is pre-configured to direct fluid around the perforator gun portion, allowing the tool to perform multiple operations including perforation in a single continuous run without requiring removal or reconfiguration between operations
3Adaptability or versatility
If fluid is directed through the perforator gun portion, then the perforation function is enabled, but fluid cannot flow through the tool for other operations like cleanout
Solution Approach 1:
The fluid directing apparatus acts as an intermediary structure with a bypass passageway that directs fluid around the perforator gun portion. This intermediary fluid path allows fluid to flow through the motor section for drilling or cleanout operations while the perforator gun remains in place, enabling flexible operation selection without complex reconfiguration

AI summary
The present invention is for a downhole tool having a perforator gun portion disposed within a housing of the downhole tool for perforating an oil and gas formation. The downhole tool also includes a bypass passageway for directing fluid past the perforator gun portion in the downhole tool to permit fluid flowing into the downhole tool to flow out of the downhole tool to facilitate an oil and gas operation. Furthermore, the downhole tool is used in a method of performing the oil and gas operation in a wellbore by pumping fluid through the downhole tool.
