About Olasumbo Areago

Senior Petrophysicist
A degree educated Petrophysicist who possesses 15 years of specialist industry experience, is results-driven and ambitious; has specialist knowledge in formation evaluation, reservoir characterization, hydrocarbon exploration and maximum/ efficient exploitation of current reserves. This experience has been gathered working in oil and gas service companies, operator and non-operators; in multidisciplinary teams sometimes sitting across continents. I am patient, approachable and will apply meticulous attention to detail, particularly in challenging environments and will remain calm when dealing with pressurised situations.

Tectonics and lithosphere dynamics Geophysical analysis Structural analysis Sedimentology and stratigraphy Reservoir geoscience Petroleum systems
University: Stanford University Degree: Short Course - Statement of Accomplishment Graduation Year: 2014 Area: Reeservoir Geomechanics Start - End Year: 2014 - 2014
University: Federal University of Technology Minna Degree: Bachelors (B. Tech) Graduation Year: 2006 Area: Geology Start - End Year: 2001 - 2006 Notes:
Getting a B.Tech degree in geology was challenging but worth it. Learning was highly practical/technical with field work every year for 5 years in both basement (Older and younger granites) and sedimentary regions (Sokoto/Bida basins) of Nigeria. This highly technical approach has made me very analytical and helps me tackle problems with relative ease. Dissertation: Petrophysical Analysis and Well log Correlation of Wells located on Alpha field, western Niger Delta, Nigeria. B. Tech thesis (2006)
