ReconAfrica’s technical team have the specialised expertise required for the exploration of the company’s Namibia and Botswana assets.

Dan Jarvie
Daniel Jarvie


Mr. Daniel Jarvie is globally recognized as a leading analytical and interpretive organic geochemist, having evaluated petroleum systems around the World. Most notably, he completed the geochemical analysis for Mitchell Energy, in their development of the Barnett formation of the Fort Worth Basin, in Texas. In 2010, he was awarded “Hart Energy’s Most Influential People for the Petroleum Industry in the Next Decade.”

Mr. Jarvie is retired Chief Geochemist for EOG Resources, one of the largest independent oil producers in North America. He is the President of Worldwide Geochemistry, LLC, working as a consultant to industry, and has also established a research lab to evaluate various aspects of petroleum systems worldwide. as well as conventional petroleum systems worldwide. His specialties include source rock characterization, especially for resource assessments, and also detailed source rock characterization for conventional petroleum systems analysis, including bulk and compositional kinetic determinations, high resolution light hydrocarbon and fingerprinting analysis, pyrolysis and catalysis studies.

Bill Cathey
Bill Cathey


Bill Cathey, President and Chief Geoscientist of Earthfield Technology, has over 25 years of potential fields interpretation experience. His clients include Chevron, ExxonMobil, ConocoPhillips and many other major and large independent oil and gas companies.

Additionally, Mr. Mitiska has valued expertise in major North American source rock plays, which includes the Marcellus, Eagleford and Woodford plays.

Mr. Mitiska has a proven track record for adding value and creating organizational growth. Geological investigations include regional basin analysis, exploration and development mapping, detailed reservoir analysis and description, prospect generation for clastic and carbonate reservoirs, 2D & 3D seismic acquisition and interpretation, reservoir engineering integration, and geological and geophysical computer modeling and mapping.

Ansgar Wanke
Dr. Ansgar Wanke


Dr. Wanke is a geologist with over 20 years of experience in various fields including regional mapping, geochemistry, hydro- and engineering geology, sedimentology and seismic stratigraphy. He joined the University of Namibia geology department in 2008, reviewed and designed several geology curricula, and headed the department from 2012 to 2015.

Ansgar Wanke
Claire Preece

Ms. Claire Preece has over 25 years experience and is well versed in Strategic and Environmental, Social, and Health Impact Assessments, environmental, socio-economic and governance reporting, gender development and equity, stakeholder engagement and the development of effective communications materials in both private and not-for-profit sectors. Additionally, her work with Boards and Operations teams has allowed her to participate in strategy and planning all the way through to implementation, a valuable continuum of skills and abilities.

Ms. Preece implements ESG Sustainability reporting and compliance and has excellent communications skills.  She has worked in the oil, gas, LNG, and mining private sectors and, with international organisations, including the World Bank, International Finance Committee (IFC), and The Canadian International Development Agency (CIDA) amongst other international and interest group organisations (NGOS and otherwise). She develops and disseminates communications, consultation and engagement components focusing on impacted and interested stakeholders with great proficiency. Her technical expertise with monitoring and audits, community-based outreach along consultation and engagement follows international best practices and her approach is fair and transparent with sustainable and tangible results.

The Technical Team also includes Dr. James Granath, Structural Geologist; see his biographical information under Directors and Officers
