Downhole Data Bus Single Port Multi-Tool Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data transfer methods from downhole drilling tools to the surface are inefficient, particularly when multiple tools are involved, as they require individual connections and have limited data transfer rates, which can lead to data loss and increased retrieval time.
Innovation Solution
A high-speed data bus system connects multiple downhole tools to a single data port, enabling fast data transfer from multiple tools to a surface computer using a wireline or fishing device, allowing for simultaneous data retrieval and configuration of tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If individual connections are used for each while drilling tool, then data can be retrieved from each tool separately, but the data transfer rate is limited and retrieval time increases
Solution Approach 1:
The patent combines multiple individual tool data ports into a single centralized data port that aggregates data from all while drilling tools through a high-speed data bus, enabling simultaneous data retrieval from multiple tools through one connection, thereby dramatically increasing data transfer rate and reducing total retrieval time
Solution Approach 2:
The centralized data port serves as a universal interface that can communicate with multiple different while drilling tools simultaneously through the high-speed data bus, replacing the need for separate individual connections and enabling multi-functional data acquisition from diverse tool types
2Ease of operation
If multiple individual data ports are used for multiple tools, then each tool can be accessed independently, but the system complexity and number of connections increase
Solution Approach 1:
The patent merges multiple separate connection interfaces into a single centralized data port that consolidates all tool communications, reducing the number of physical connections and interface management requirements while maintaining the ability to access individual tools through the unified interface
Solution Approach 2:
The high-speed data bus acts as an intermediary between the single centralized data port and multiple while drilling tools, managing all data transmissions and tool communications through this intermediate communication channel, thereby simplifying the external interface while handling multiple internal connections

AI summary
A method for transferring data between a surface computer and a downhole assembly may include connecting the surface computer to a single data port in the downhole assembly, transferring data between the surface computer and a first while drilling tool through the data port, and transferring data between the surface computer and a second while drilling tool through the data port.
