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.
Experience
Company: Wellynx
Duration: Nov 30, -0001 to Nov 30, -0001 .
Description:
As Wellsite Geologist my responsibility is supervising the day to day geological operations on the rig including but not limited to: reporting to operations geologist, assisting exploration team in formation evaluation, supervise mud logging and wireline logs crews and units, quality check of mud logging/wireline equipment and reports, pick up formation tops and casing points using cuttings, ROP, LWD/MWD and wireline logs to make correlations with closest wells, describe and evaluate cuttings, make lithological and stratigraphical interpretation, wireline logging witness for pioneering hydrogen storage wells in north Italy in clastic reservoir. I used Wellview software to do daily geological report. I compile daily geological and final well reports for geological exploration team in town.
