Improved communications will not only reduce cost, but will also greatly assist in exploiting and even
safeguarding mature assets, because the wrong decisions can cause a well to close forever. In addition, there
will be significant health, safety, and environment bottom-line improvements.
Next Steps
Key to achieving Petrobel's vision of the digital oilfield is in taking a holistic view of the entire production and
value chain and supporting this with an architectural approach to network design. In this way the entire network
can be developed as the platform on which to build end-to-end business services and processes. 
Petrobel is finalising plans to create an offshore wireless coverage area using Broadband Wireless Wide Area
Network and WiMax IEEE 802.16 technology to interconnect the Cisco wireless mesh technology covering the rig. 
The WiMax antennas will provide 18 Mbps coverage within a 25 kilometer radius, enabling even supply vessels and
other logistics operations to benefit from access to secure networking. For example, always-on communications could
make possible the use of RFID (Remote Frequency Identification) asset tracking and supplies replenishment. There are
even plans to equip unmanned production platforms with IP-Webcams and audio systems as part of global security
and safety CCTV (Close Circuit TV) network that will help ensure their live monitoring from the headquarters.
The company is also planning to significantly improve its backhaul links to shore-based facilities. Although
recent advances in compression techniques will increase effective VSAT bandwidth fivefold, these upgraded
links are destined to provide redundancy backup to WiMax systems. One such system, from Redline
Communications, was deployed successfully for about eight months to link a rig 42 kilometers offshore in the
Port Fouad field back to an IEOC base station at Port Said with a minimum bandwidth of 18 Mbps. 
The service and financial case for wireless is already proven. The annual capital expense of a 128 kbps VSAT
link in Egypt is US$40,000, with operating costs for space segment totalling US$48,000 each year. In comparison,
an 18 Mbps broadband wireless link requires equipment costing US$15,000 and has annual operating
expenses of just US$3,000.
Consequently, projects are being finalised to extend wireless broadband and optical fibre connectivity to all the
shore-based plants and rigs operating across the Sinai and the Red Sea. From an operational perspective, these
projects are aimed at providing a transparent, integrated WAN that enables a highly secure, real-time view of
what is happening on the front. This will be possible from the Cairo headquarters and, eventually, from the
intelligent operations centres worldwide.  
When complete, Cisco First Mile Wireless, with Cisco Unified Communications will provide the foundation for the vision
of the digital oil field, with rig operations moving – albeit virtually – from the headquarters' locale into the main office.
Technical Implementation 
Petrobel's vision of the network as a platform uses an architectural framework that Cisco calls its Service
Orientated Network Architecture (SONA). SONA delivers business solutions to unify network-based services
such as security, mobility, and location with the virtualization of IT resources. Using this framework, Petrobel is
assured that each discrete networking project is part of the bigger, more strategic roadmap.
The first step has been to build mobility services using Cisco Aironet 1500 Series Access Points, and the Cisco
2006 Series WLAN Controller which supports zero-touch configuration and simplified the installation of the
network for Petrobel. 
“This technology gives us the opportunity to more
effectively assist the production team to reach the right
decision. I expect to see it in place on all rigs within the
next five years.”
