The Challenge

Under pressure to meet federal mandates, to preserve assets, and to protect the public, oil and gas operators face a range of technology challenges, from collecting, maintaining, and integrating pipeline transmission and gas distribution data to implementing risk assessment, mitigation, and accident control.

In the past 35 years, we have mapped more than 100,000 miles of corridor and have assisted our clients in classifying more than 75,000 miles of pipeline using our software.
