Oil and Gas, Natural Gas

With increasingly demanding requirements for oil and gas projects and tighter production plants, the importance of engineering experience and specialised industry application solutions in these fields is paramount. HollySys always works out solutions with end users to handle challenges starting with pre-phase planning to the whole oil production process, providing application solutions to cover their client’s every need, helping clients simplify their processes, improve safety, reduce risks, reduce labor intensiveness and machine downtime costs, shortening the time of the client needs for obtaining crude oil. We can analyse and propose the correct sequence and procedures, ensuring that the client maximises its profits and returns in the shortest time possible.

HollySys has a team of experienced staff and a series of reliable and open solutions with a wide coverage that can help you reduce the overall project implementation risks and ensure attractive returns on investments.

Typical System Design

HOLLiAS MACS-SCADA is a multi-functional, flexible, and distributed integrated-monitoring, data acquisition, and data integration software package which uses an open-framework software system, and multiple-platform support mode. Every layer is uniquely designed, logic-related, and expandable, enabling the system’s openness to be readily expanded. In this design mode, the application design and engineering experience is reused, where the software has a modular structure, supports platform sharing, and component reusing. This software incorporates the HollySys’ professional experience in the SCADA field and needs of clients, especially high-end leading industry clients like the China Railway Corporation. Continuous improvements have been made during the last decade to make this into a leading standard in the Chinese SCADA industry.
