RT138 – For Workover Rig

1. Description

A Workover Rig Monitoring System (RT138) is a comprehensive solution designed to monitor and optimize the operations of workover rigs, which are essential in the oil and gas industry for well intervention and maintenance. This monitoring system leverages advanced technology and data analysis to enhance the safety, efficiency, and productivity of workover rig operations. The RT138 system typically consists of sensors, data acquisition devices, communication infrastructure, and software applications. These components work together to collect real-time data from various aspects of the workover rig, including hydraulic systems, power units, drilling fluid parameters, and overall rig performance. The collected data is transmitted to a centralized control centre or a digital platform (HMI), where it is processed, analysed, and visualized in a user-friendly format. Operators, supervisors, and engineers can access this information to gain valuable insights into the rig's performance, identify any operational issues or anomalies, and make data-driven decisions to optimize rig operations.

The workover rig monitoring system offers several key benefits. Firstly, it improves safety by continuously monitoring critical parameters such as weight on bit, hook load, wellbore pressures, toxic & combustible gas and fluid levels, thereby helping to prevent accidents and equipment failures. It also enables proactive maintenance by detecting early signs of equipment wear or malfunction, allowing for timely repairs and reducing downtime.

Furthermore, the system enhances operational efficiency by providing real-time performance metrics, allowing operators to optimize drilling parameters, adjust equipment settings, and make informed decisions to increase overall productivity. It also facilitates better resource allocation and scheduling by providing visibility into the utilization of rig assets and personnel. Additionally, the workover rig monitoring system enables remote monitoring and control, reducing the need for personnel to be physically present onsite. This capability is particularly valuable in remote or hazardous environments, as it minimizes risks and improves operational flexibility.

Overall, a workover rig monitoring system is a powerful tool that enables real-time monitoring, analysis, and optimization of workover rig operations. By leveraging datadriven insights, it helps improve safety, efficiency, and productivity, leading to cost savings and enhanced performance in the oil and gas industry.

2. System Architecture

The Workover Rig Monitoring System consists of several interconnected components. These include:

  • Sensors and Data Acquisition: Various pressure sensors, Flow & Level Sensors, Gas detection sensors, are strategically placed throughout the rig to collect data on key parameters such as hook load, fluid pressures, temperatures, H2S & HC detectors. Data acquisition devices capture this information and transmit it to a central hub for processing.
  • PLC System & Communication Infrastructure: The sensors installed on the BOP Control Unit talk to a PLC based system. The PLC system acquires raw signal from the sensors and conditions it in a format which is understandable by the RT138 local system. The system relies on a robust communication infrastructure, to transmit data from the rig to the central monitoring station (HMI). This ensures timely and seamless data transfer.
  • RT138 Central Monitoring and Control: At the heart of the system, a centralized monitoring station receives, processes, and analyses the data. This station is equipped with powerful software applications that provide real-time visualization, analytics, and control capabilities. The RT138 System is a standalone unit that is installed on the Rig Side and talks to the PLC system described above. This system captures the processed sensor data from the PLC unit and displays it in an intuitive UI format. The system samples and logs all the data at a rate of 1Hz and is capable of maintaining a continuous log of up to 5 years.
  • Visualization and User-Interface: The monitoring system includes user-friendly visualization tools and a graphical user interface (GUI) that display the real-time rig data and analysis results. These visualizations can include interactive dashboards, charts, graphs, and alarms to provide operators with a comprehensive overview of the rig's performance and status.
