Downhole Stabilizer Wireless Telemetry for Real-Time Logging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless logging tools used in drilling operations do not provide real-time feedback on their deployment status, leading to potential incorrect deployment issues that are only discovered during data retrieval, resulting in lost drilling rig time and valuable data loss.
Innovation Solution
A logging system with a drill stabilizer equipped with electronics that can wirelessly communicate with a logging tool string, including sensors and a communication interface, allowing for real-time data collection and transmission from the drill stabilizer to the logging tool string, enabling immediate detection and correction of deployment errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless logging tools are used without real-time communication capability, then device complexity is reduced, but reliability of deployment monitoring deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the drill stabilizer continuously monitors deployment status and wirelessly transmits real-time data to the logging tool string. This feedback loop enables the operator to immediately detect deployment errors and correct them, significantly improving deployment monitoring reliability while maintaining manageable system complexity through modular wireless communication components.
2Loss of time
If real-time data transmission is implemented, then loss of time is reduced, but use of energy increases
Solution Approach 1:
The system employs periodic data transmission rather than continuous transmission, where the drill stabilizer and logging tool string exchange deployment status information at regular intervals or upon detection of status changes. This periodic communication approach minimizes energy consumption while still providing timely deployment monitoring to prevent significant time loss.
3Reliability
If wireless communication components are added to drill stabilizer, then reliability of deployment detection improves, but device complexity increases
Solution Approach 1:
The drill stabilizer is designed with multi-functionality, serving both its primary stabilization function and acting as a communication node for deployment monitoring. By integrating wireless communication capabilities into the existing drill stabilizer structure rather than adding separate monitoring devices, the system improves deployment detection reliability while minimizing the increase in overall device complexity.

AI summary
A logging system and method for use in a wellbore formed in an earth formation. A tubular conduit that extends from the surface into the wellbore is included in the system. The conduit includes a stabilizer with sensors to obtain data from the wellbore. A communication interface is used to communicate data from the stabilizer to the logging tool string. Also, a surface communication and control device, along with a telemetry device can be included in the system. The telemetry device could be used to send and receive data to and/or from the surface communication and control device, if needed. Also provided is a logging tool string that is capable of passing from a position within the conduit to a position outside the lower end of the conduit. In addition, a memory storage device used to and store data collected from the wellbore for further analysis and communication.
