Werner M. Heigl graduated in 1993 with a Diploma in geology from the University of Munich, Germany. In 1995 he joined Schlumberger Wireline and Testing as a Field Engineer. He worked in most parts of Europe including the North Sea, and held assignments as Engineer-in-Charge and Borehole Seismic Specialist. In summer 2000 he transferred to Trinidad and Tobago, W.I., as Field Service Manager responsible for open and cased hole logging operations as well as training local companies in formation evaluation principles. In spring 2002, he left Schlumberger and joined the Center for Petrophysics at the Colorado School of Mines where he is currently pursuing his PhD under Prof. Max Peeters. His thesis research focuses on the analysis of local regularity of well logs and borehole seismic data, and how it can be used to characterize lithological and fluid boundaries in the subsurface.
