The increase of activity in the oil and gas market in North America is driving change in the way mobile systems are deployed. As drilling in the US increases, there is also a great need for mobile services such as well monitoring and stimulation. The equipment used for these applications is typically designed into a truck or trailer, or mounted on a mobile skid that allows the systems to be moved from site to site as needed. The technologies that allow these systems to communicate with each other are undergoing a change. Systems that formerly used serial fieldbus protocols are now being redesigned in favor of their Ethernet-based equivalents. Another trend is the move from wired to wireless network infrastructures, which gives operators the convenience of simpler deployment and takedown when equipment is moved from site to site.
