Equinor
Duration: Nov 30, -0001 to Nov 30, -0001 .
Description:
Principal petrophysicist for the appraisal phase of the Brazilian Santos basin Bacalhau integrated project, an
ultra-deep water, pre-salt, over pressured complex carbonate reservoir.
Providing real-time petrophysical interpretation of new open-hole wells in support of key decision-making
process.
QC and analysis of an elaborate multi-well dataset such as WL & LWD logs, borehole acoustic & resistivity
imaging, core & SWC point decision for RCAL and SCAL.
Cased hole formation tests support, perform PLT fluid flow and CBL cement log data analysis.
Delivering interpretation parameters as clay volume, porosity, water saturation, permeability, formation
pressures, mineralogy, acoustic/elastic properties, flow zones and zone summations results input to
the geological and reservoir models used for development & production planning.
Generate advanced analysis such as rock typing, saturation height and fluid substitution modeling.
Development phase open-hole wireline, LWD and coring acquisition planning.
Mentor less experienced petrophysicists.
