概要 Saudi Aramco, the state-owned national oil company of Saudi Arabia, is the world's largest oil corporation in terms of proven crude oil reserves and production. At the end of 2006, its annual production of crude oil neared 3.4 billion barrels. As their oil and gas fields often spread across vast distances in a severe desert climate, Aramco needs a reliable monitoring system to address harsh environmental conditions. At the same time, a high bandwidth for transmitting data, voice, and video is also required for better wellhead monitoring.

Project Intro

Saudi Aramco, the state-owned national oil company of Saudi Arabia, is the world’s largest oil corporation in terms of proven crude oil reserves and production. At the end of 2006, its annual production of crude oil neared 3.4 billion barrels. As their oil and gas fields often spread across vast distances in a severe desert climate, Aramco needs a reliable monitoring system to address harsh environmental conditions. At the same time, a high bandwidth for transmitting data, voice, and video is also required for better wellhead monitoring.
 

System Requirements

• Industrial-grade devices that are capable of operating well under extreme temperatures
• An efficient network with high bandwidth for data, voice, and video transmission
• A reliable network for long-distance transmission between oil and gas fields
• Certified explosion-proof devices for hazardous locations
• Fast auto-recovery to prevent data loss in case the network goes down

 

Moxa Solution

This operation covers 500 widespread oil, gas, and water wells located in Khurais area. Aramco developed a remote monitoring system, including wellhead SCADA and CCTV, and wellhead control automation, which includes compressor control, pumping unit control, gas lift control, and injection control. RTUs (Remote Terminal Units) and PLCs are used to collect and forward these data. IP phone, CCTV and Moxa's VPort 351-T are also implemented on site for maintenance and security service. Each oil field uses a VPort 351-T industrial video encoder that connects to the camera through a coaxial cable, and the other side connects to Moxa's EDS-510A-1GT2SFP-T industrial managed Ethernet switches for video image encoding and transmission. The EDS-510A-1GT2SFP-T was chosen to connect those devices and form a communication network with GOSP (Gas Oil Separation Process) substations. Each substation uses Ethernet switches to connect to the main ring topology, and the reliability of the network is enhanced by coupling sub-rings together. The ring topology and coupling are realized with the EDS-510A-1GT2SFP-T switches, which support Turbo Ring redundancy with a recovery time of less than 20 ms.

 

With an open standard Ethernet and Gigabit port design, the EDS-510A-1GT2SFPT can fulfill the voice, video and data transmission for oil well monitoring, and its extended operating temperature range (-40~75°C) is especially well suited for applications in harsh industrial environments. In addition, the EDS-510A-1GT2SFPT switches are DNV and Class 1, Div. 2 certified to ensure reliable operation and communication between oil and gas fields and the control centers.
