Despite sustainability advances, the world is ever thirstier for oil and natural gas, especially in developing regions with a growing middle class. To supply this ravenous and accelerating demand, producers are forced to explore more widely and deeply than ever before and cope with far higher capital operating costs, yawning skill and experience gaps, and increasing regulations.

"Operators are overwhelmed with data, and enterprise-level managers are also struggling with all the 'big data' in their organizations," said Elizabeth Parkinson, market development manager for Rockwell Automation's oil and gas division, at this morning's Oil & Gas Industry Forum at the Automation Fair in Philadelphia.

"At the same time, subject-matter expert pools are shrinking, so resources need to be shared," Parkinson continued. "However, remote visibility empowered with live data is challenging, so decision-makers aren't equipped to do it and often focus on incorrect priorities. The actions that drive better capabilities include applied automation via improved network and controller loading, avoiding bottlenecks, designing systems with process sub-system dynamics in mind and optimizing system performance. It's also vital to present data on dashboards and use better reporting and data strategies, but also maintain firewalls and leverage other services, such as cloud computing."

Rockwell Automation, its system integrators and end users are coming up with some stunning innovations to help increase the efficiency and productivity of their production applications. For example, the Oil & Gas Industry Forum showcased three creative process control and automation projects. Perhaps alerted to these innovations, about 250 visitors to the fair stopped by and turned the forum into a standing-room-only event.

"Rocket Engine" Extraction

First up, Mei Lixin, CEO of Jiangsu Great River Petroleum Technology in Jiangyin, China, reported that his eight-year-old company has developed a new method—Composite Heat Carrier Generator (CHCG)—to greatly increase oil and gas yields, and has even designed an explosion-proof version for offshore platforms. The firm provides technical and support services to increase production yields for China's largest oil and gas companies, including CNPC, CNOOC and SinoPec.

"There have been three traditional ways of enhanced oil recovery—thermal recovery, gas injection and chemical injection. We think there is a fourth way by combining the original three," said Lixin. "It's based on the working principle of combining fuel, air and water in a sealing room, and then injecting them at extremely high temperature and pressure—almost like a rocket engine—into the target reservoirs, which are mostly in light oilfields, heavy oilfields and low-permeability."
