Wireline Well Automation Platform for Winch Shutdown
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for controlling independent winch systems in wellbores lack a centralized, separate control mechanism that can continuously receive and respond to operating parameter data in real-time, leading to potential unsafe operating modes and lack of automatic shutdown capabilities.
Innovation Solution
A wireline wellsite automation (WWA) platform that is completely separate from the independent winch systems, continuously receives data on operating parameters, and automatically takes control of the winch to adjust operational parameters based on feedback, ensuring safe operation and implementing automatic shutdown procedures in case of data interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized separate control mechanism is implemented to continuously monitor winch operating parameters, then operational safety and control precision are improved, but system complexity increases
Solution Approach 1:
A separate WWA platform acts as an intermediary control system that receives data from the independent winch system via data bus 38. This mediator monitors operating parameters continuously and can take control of the winch independently, improving safety without requiring integration into the original winch control architecture.
Solution Approach 2:
The control system is divided into two independent parts: the original independent winch system 56 and the separate WWA platform 54. This segmentation allows the monitoring and control functions to be performed by a dedicated separate system, reducing complexity in the original winch system while maintaining overall system reliability.
2Speed
If real-time data reception and automatic control takeover are implemented, then response speed and automation level are improved, but information processing requirements and system complexity increase
Solution Approach 1:
The WWA platform continuously receives operating parameter data from the winch system via data bus 38, creating a real-time feedback loop. This enables the system to monitor winch operation continuously and automatically take control when safety thresholds are exceeded, achieving fast response without requiring complex predictive algorithms.
3Reliability
If complete separation from the winch system is maintained, then system independence and reliability are improved, but integration difficulty and communication complexity increase
Solution Approach 1:
The data bus 38 serves multiple functions: it enables the independent winch system to operate autonomously while simultaneously allowing the separate WWA platform to monitor and control the winch. This universal communication interface achieves system independence without requiring complex dedicated communication protocols.

AI summary
Systems and methods presented herein include coordinating behavior with independent winch systems and a wireline wellsite automation (WWA) platform, consisting of a variety of distributed services and applications, and that is completely separate from the independent winch systems, such that the coordination enables the WWA platform and an independent winch system to effect shutdown of the independent winch system, based on operating parameters received from the WWA platform and autonomous operating parameters transmitted to the independent winch system. For example, in certain embodiments, a WWA platform that is completely separate from a multiline unit winch system may be configured to continuously receive data relating to operating parameters and transmit control signals to the winch units of the multiline unit, in order to effect a multiline winch shutdown.
