Automated CCTV Video Display Control for Oil Well Construction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current well construction systems lack automated video display management, requiring human operators to manually control CCTV systems to monitor well construction progress, which is inefficient and prone to errors.
Innovation Solution
A closed-circuit television (CCTV) system with video cameras at various locations within the well construction system, a video output device, and a control system that includes a processor and memory to store video display settings, allowing automatic display of video signals based on predefined settings for different operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual control of CCTV system is used, then operator can select and adjust video feeds, but operational efficiency is reduced and errors are more likely
Solution Approach 1:
The system performs video feed selection and display automatically based on operational data without requiring manual operator intervention. The control system autonomously determines which video feeds to display based on the operational phase, eliminating the need for operators to manually select and adjust video feeds while maintaining full monitoring capability
Solution Approach 2:
The system pre-configures video display settings for different operational phases before operations begin. Video feed associations with operational phases are established in advance, allowing the system to automatically switch to appropriate video feeds when operational phases change, eliminating real-time manual selection
2Productivity
If automated video display is implemented, then operational efficiency is improved and manual intervention is reduced, but system complexity increases
Solution Approach 1:
The control system serves multiple functions: it monitors operational phase changes, retrieves associated video feed settings, and automatically configures video display. This multi-functional approach consolidates what could be separate complex systems into a single integrated control unit, managing complexity while achieving automation
Solution Approach 2:
The control system acts as an intermediary between the operational phase detection mechanism and the video display system. It receives operational phase information, processes it through pre-configured associations, and generates appropriate video display commands, simplifying the interaction between different system components
3Reliability
If manual monitoring of well construction progress is used, then operator attention is required, but time consumption increases and monitoring quality may vary
Solution Approach 1:
The system automatically monitors well construction progress by continuously tracking operational phase changes and corresponding video feeds without requiring sustained operator attention. The autonomous monitoring maintains consistent quality while freeing operators from continuous manual observation tasks
Solution Approach 2:
The system establishes feedback loops where operational phase detection triggers automatic video feed selection and display adjustments. This continuous feedback mechanism ensures that the appropriate video feeds are always displayed corresponding to current operational activities, maintaining high monitoring quality without manual intervention

AI summary
A closed-circuit television (CCTV) system for use at a well construction system to form a well at an oil/gas wellsite. The CCTV system includes a video output device and video cameras at the well construction system. A control system is communicatively connected with each video camera and the video output device. The control system receives video display settings from a human wellsite operator, receives the video signals from the video cameras, and automatically displays on the video output device one or more of the received video signals based on the video display settings.
