    Ed’s experience and training was obtained from Exxon Corporation and affiliates from 1979-1990 where projects were completed in the Gulf of Mexico, Latin America and Europe. Subsequently, interpretation and consulting projects were conducted for the Calibre Consulting Services Company and TGS-Nopec Geophysical company from 1990-2000. During this time Excalibur Interpretation Company was co-founded to provide consulting and geophysical interpretation service projects. His prior experience includes work as an engineering geophysicist on major industrial and offshore drilling locations for site suitability and geo-hazards investigations with Dames and Moore and Fairfield Industries from 1974-1979.

    Ed is registered in Texas as a Professional Geoscientist (Geophysics) # 3141.

  • Gloria Eisenstadt

    Gloria Eisenstadt is an industry-recognized expert in structural geology. She has over twenty years of international experience in the analysis and interpretation of 2-D and 3-D seismic interpretation in complex structural settings; extensional, inversion, thrust belts, and salt/shale tectonics. She has managed large regional and basin studies integrating seismic interpretation with other data sets.
