Wellhead Remote Monitoring and Maintenance Communication Network

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.

Intrusion Detection with SNMP and IP Video in Factory

Wars and oils are the hottest issues in the Middle East. And the oil storage tanks are usually the target of attack during wartime. Typically, oil storage tanks and refining equipment are the most important parts of the oil refinery industry. To protect hose facilities from being damaged is a top priority of those oil vendors. One of our customers planned to combine video and alarm signals in one fiber network. In addition to video surveillance, digital I/O devices in the field were used for remote monitoring and alarm. However, the IP surveillance system is a bandwidth killer. To assure those alarm messages can be delivered with precise time stamps is the key. The client used SNMP to monitor their network devices and wanted to integrate this new intrusion detection system with their remote monitoring system. SNMP, Fiber network and low bandwidth consumption are the prerequisites for the new system.

System Requirements

• SNMP support for each device
• I/O device/status controlled by SNMP
• Device status reporting by SNMP traps
• Large bandwidth using fiber ring architecture
• Industrial-grade video surveillance to withstand bad weather conditions
 
Moxa Solution  
To implement a reliable network backbone that can support 200 IP video feeds, the customer used the EDS-510A managed Ethernet switch to build a redundant Gigabit Ethernet network. Although the EDS-510A's two digital input channels are insufficient for extra monitoring devices, the ioLogik E2210 Active Ethernet I/O server was able to provide the necessary digital I/O channels. The built-in SNMP support and multiple I/O channels of ioLogik E2210 are available for control and monitoring by SNMP, no additional management software is required. In addition, status changes of each I/O channel can be actively reported by SNMP traps, so there is no need for data polling.

Wireless Communications Infrastructure in the Oil Field

Few markets have more to gain from reliable, high-capacity wireless broadband solutions that cover dozens or even hundreds of square miles than the oil & gas industry. Reduced lifting costs, remote video surveillance, VoIP and even multimegabit mobile access over water or on wheels can be delivered under a single solution. But the big benefits can only be realized using solutions that are specifically designed for the harsh oil & gas environment.

The oil patch is a dynamic place where things constantly change, the environment is unforgiving and the locations are often remote. It is a place where function is everything, and everything has a purpose. That purpose is to squeeze out every possible drop of productivity. In the modern oil field effective communications networks are key to enabling and maximizing efficiencies and driving down overall lifting costs. Today, the best communications infrastructure technology for the oil & gas industry is wireless broadband.

Unlike traditional point-to-point microwave, wireless broadband or “WiMAX” refers to wireless cells many miles in diameter, each enabling anyone or anything within the footprint to be connected. This “multipoint” method of access is very economical and provides extremely reliable links and excellent redundancy options to ensure that you remain connected.
