Meet the Team


Isolda Griffiths

Isolda is a petroleum economics evaluation engineer.  She holds a BS degree in geophysics from Argentina, an MS in petroleum engineering and an MA in energy economics both from the University of Texas at Austin. Her multidisciplinary background has helped her to better communicate and work in diverse teams and to understand, identify and quantify risks and opportunities from a holistic point of view. She has been involved in the economics, decision and risk analysis of multi-billion dollar projects in GoM deepwater, US onshore and internationally. Her knowledge, creative and out of the box thinking have helped her in the creation of user-friendly processes for economic evaluations, economics assurance reviews and the economic side of the reserves booking.  Isolda has worked for APC, SLB, Shell and BHP.

Jennifer Wilson

Jennifer holds a bachelors degree in Petroleum Engineering from Texas A&M University. Her experience in the oil and gas industry started with Chesapeake Energy as a Barnett Shale production engineer working with 42 drilling rigs. Her interest in data analysis began after she put together a data study to discover an optimal time to run tubing in a new well. Most recently, Jennifer has worked on the start up of a CO2 field and recycle facility for Tabula Rasa Energy all the while organizing well data and financial process optimization. Jennifer’s multifaceted experience has exposed her to several programming languages, software, and disciplines within the industry. She is a passionate engineer who is good at framing end goal objectives and working with her teammates to accomplish those goals.
