DAILY PARAMETER CONTROL AND MONITORING

Daily parameter control and monitoring is done through the Supervision, Control and Data Acquisition (SCADA) systems. Using radio and/or fiber optics, this technology allows actions to be carried out in real time and provide automatic measurement of operational parameters and surface and bottom conditions, including:
• Temperature.
• Pressure.
• Injection rate.
• Oil, gas, and water production rates.
• Production behavior predictions.

AUTOMATION

As an integral part of the process, Nakasawa has incorporated operational parameter monitoring during the injection and post-injection stages to keep close control over all operations.

To guarantee optimum equipment performance and obtain high process efficiency, the company has incorporated the installation of cutting-edge technological sensors to measure downhole and surface parameters.

Sensors record data on parameters such as pressure and temperature, and fiber optics (DTS) and thermocouples verify the progressive state of the measurement system, system efficiency indicators, amplitude, and phase digits. In addition to documenting sensor performance over time, this setup also means potential problems can be detected in advance.

With process automation, it is possible to generate second-by-second pressure and temperature trend graphs. This speeds the decision-making process and helps optimize production in real time.

All data is collected and integrated into a state-of-the-art PLC and linked to a central database, and is accessible through an application that allows the user to view the current status of the steam generation and injection process in real time and on all mobile devices,

The data transmission can be executed directly through satellite technology by means of control loops with the measurement sensors, and using a software and/or application for remote visualization. In addition, the data transmission architecture can be adapted through the following means:

  • Scada System
  • Fiber Optics
  • Radio Signal
  • GSM Frequency (Cellular / Modem)

In addition to data availability, the Super Matroid Heater and Super Matroid Cyclone have a system for predicting steam injection parameter trends through mathematical algorithms that allow for the execution of necessary optimizations.

Nakasawa has managed to notably improve the quality of the information, reducing the effort for its acquisition and processing.In addition, the technical personnel is highly trained to achieve the best analysis of the operation and seek continuous improvements.
