Sponsoring and Presenting. At the NAAMLP Conference, Pioneer will present Subsidence Monitoring with a Survey Network: Comparison of Post Processing Techniques. Ground subsidence above abandoned mines poses a threat to the safety of surface infrastructure. A subsidence-monitoring network can sometimes quantify risks. Join Jeff Riedel as he highlights examples of various methods to increase the confidence of a subsidence-monitoring program. Join us Monday, September 26 at 2:30 (Subsidence and Geophysical Methods session).
