About Us

Our Company

PayZone Inc. (PZI) was founded in 2002 by Deborah M. Olson, formerly a partner in Digital Petrophysics, Inc. (DPI). For over 30 years our principals have been solving reservoir problems by integrating geology, petrophysics, and engineering with innovative technology. We offer comprehensive reservoir evaluation services, including:

  • Geology and geophysics
  • Reservoir modeling
  • Petrophysical analysis (including cased hole) and field studies
  • Image log interpretation
  • Reservoir engineering and management, field development, and economics

Clients include a number of major oil companies, including Occidental, Chevron, Shell, Mobil, and Exxon.  We have also worked for a number of independent operators on both exploration and development projects.

Our staff includes senior professionals each with 25 to over 40 years of experience in petroleum geology, log analysis, petroleum engineering, geophysics, core acquisiton/analysis, and wireline operations.  We have diverse experience in many areas around the world, including North America, the Middle East, South America, and Asia. We have worked with many different reservoir types and fields from initial discovery through redevelopment, EOR implementation, and evaluation for acquisition or divestiture.
