About Stefano Nava
Wellsite Geologist
A skilled wellsite geologist 21 years of extensive experience in onshore/offshore oil and gas, geothermal wells. Executed several conventional and unconventional onshore/offshore projects (shallow and deep waters, high pressure/high temperature, H2S reservoirs and with total or partial losses) consisting of geosteered exploration, development and appraisal wells in carbonate, clastic, evaporite and basement reservoirs. Motivated and diligent team player utilizing good interpersonal and communication skills and strong analytical mind-set to learn quickly, to analyse the situation, identifies requirements and provides solutions.
