Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Downhole drilling operations face challenges in efficiently retrieving and transmitting data from downhole tools, managing inventory, and tracking the location and status of these tools, especially in hazardous environments and during transportation, leading to potential loss and increased downtime.
Innovation Solution
A downhole tool interface that connects to downhole tools on the surface, featuring a communication port for data retrieval and transmission, local storage, wireless communication, and status sensors to track location and handling conditions, allowing for remote data access and reducing human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If data is stored on downhole tools during drilling operations, then data availability is improved, but data retrieval time and downtime increase when tools need to be accessed or replaced
Solution Approach 1:
The patent extracts data from downhole tools and stores it in a database system on the surface. The interface device retrieves data from tools when they are at the surface and transfers it to external storage, separating the data storage function from the downhole tool itself. This allows tools to be quickly replaced without waiting for data retrieval.
Solution Approach 2:
The system performs preliminary data retrieval and storage actions while the downhole tool is still at the surface location before it is deployed or while it is in standby. The interface device automatically detects when a tool is present and initiates data transfer in advance, so that when the tool needs to be replaced or accessed, data is already archived.
2Productivity
If manual inventory management and tracking of downhole tools is performed, then operational simplicity is maintained, but efficiency and accuracy of inventory management deteriorate
Solution Approach 1:
The interface device serves multiple functions: it acts as a communication interface for data retrieval, a database system for data storage, an inventory management system for tracking tools, and a wireless communication node for transmitting information. This multi-functional design consolidates what would otherwise require separate systems into a single integrated device.
Solution Approach 2:
The system automatically performs inventory management tasks without requiring manual intervention. The interface device autonomously detects downhole tools, retrieves their identification information, updates the database, and transmits inventory data wirelessly. This automation eliminates the need for manual tracking while maintaining system simplicity from the user perspective.
3Reliability
If downhole tools are transported and stored without monitoring, then operational simplicity is maintained, but risk of loss or damage increases
Solution Approach 1:
The interface device includes sensors that continuously monitor the status of downhole tools during storage and transportation, such as location, temperature, humidity, and physical condition. This sensor data is fed back to the database and transmitted wirelessly to stakeholders, providing real-time feedback on tool status without requiring active human monitoring.
Solution Approach 2:
The interface device acts as an intermediary between the downhole tools and the external environment. It provides a controlled interface that protects tools during handling while enabling data exchange and monitoring. The device shields tools from direct exposure to potentially harmful environmental conditions while maintaining visibility into their status.
4Loss of information
If data is transmitted wirelessly from surface location, then real-time data availability is improved, but energy consumption and communication reliability may worsen
Solution Approach 1:
The wireless transmission system operates periodically rather than continuously. Data is transmitted in batches when triggered by specific events, such as when a downhole tool is connected to the interface, when data is updated in the database, or at scheduled intervals. This periodic operation reduces energy consumption compared to continuous transmission while maintaining data availability.
Data Source
AI summary
A downhole tool interface is connected to a downhole tool at a surface location. The downhole tool interface retrieves downhole information and wirelessly transmits the downhole information to a remote computing device. The downhole tool interface remains connected to the downhole tool during storage and/or transportation. The downhole tool interface collects status information to transmit to a remote computing device, allowing a drilling operator to better understand the conditions during storage and/or transportation.
