Mr. Burgers has diversified exploration and production experience in the oil and gas industry, predominantly with ExxonMobil until retirement. He has geological, geophysical and operational experience domestically, as well as internationally. His recent production geology work in conjunction with a reservoir engineer in MX Oil is focused on opportunities in Texas, Oklahoma, Kansas and Louisiana. The plays involve recompletions in conventional as well as development of unconventional plays in the Tertiary, Austin Chalk, Eagle Ford, and Buda. During his employment with ExxonMobil he also worked on the La Luna and Tablazo un-conventional plays, as well as the heavy oil plays in Colombia. Significant time was spend in ExxonMobil on CO2-EOR worldwide opportunities.

Earlier in his career he worked mostly in Exploration on regional evaluations. Mr. Burgers has identified pre- and post-salt opportunities and performed many regional studies. Some of his study areas include Offshore Shelf and Deepwater Gulf of Mexico (Both Mexican and US part), Mexico Onshore, Sub-Sahara Africa in particular Nigeria, Offshore Brazil, and Colombia (On & Offshore). He earned a master’s degree in geology from Leiden University, The Netherlands, and he is fluent in many languages including English and Spanish. He is in the possession of the US Green Card.
