Ivan Olea, M.Sc. Ivan worked at the Mexican Petroleum Institute doing research and wellbore modelling for reservoir simulation studies (vertical flow performance modelling) of naturally flowing wells and on artificial lift systems. He has been in S&P Global (formerly Fekete Associates/IHS Markit) since 2008. His initial role was to provide technical expertise in the development of nodal analysis and production calculation software tools including calculations for the Harmony suite. He then joined the consulting team where he was involved in the modelling and analysis of numerous wellbore dynamics, production optimization and reservoir engineering projects including gas well deliquification, artificial lift systems evaluation, acid gas disposal phase behavior modelling, compositional well modelling, multilayered well modelling, reserves evaluations, rate transient analysis (RTA) applied to reservoir and well production optimization problems. Currently, he uses his subject matter expertise in the development and research of data analytics, data visualization, data driven and machine learning models of energy related problems.
