offshore Atlantic and Caribbean, Red Sea, Gulf of Thailand)
 4.5 years of research in rock properties/basin modeling - thermal modeling, compaction under
vertical and lateral stress, diagenesis, pore pressure, integration of physical rock properties with
petrology and wider geology (case studies in NW Borneo, GoM and elsewhere)

Consulting Geologist

Projects
o Red Sea, Gulf of Thailand (Client: Mubadala Petroleum, Abu Dhabi / Bangkok) – building
models for multiple basins ranging from simple maturity to complex petroleum
migration studies and volume estimates.
o Brazil equatorial margin (Client: Maersk Oil, Houston) - building a complex basin model
at a broad continental margin scale (150+ wells). Delivered a range of model outcomes
predicting HC charge nature, distribution and timing. Integrating model results into the
client’s play-based exploration framework.
o Support to PSA community (PSA group LinkedIn, YouTube, Webinar series)

Research Geologist – Basin Modeling
 Rock properties and basin modeling research
 Project manager of most of the projects, in which I was involved
 Reviewed porosity and diagenetic models for cements and amorphous silica for sands and
mudrocks, also with regard to unconventional gas shales; tested and calibrated them. Explored
their effects on pore pressure and implications for other rock properties in basin model;
developed guidelines for modelers. Applied to existing basin models in GoM (3D) and Fort Worth
basin (1D) and to a new 1D model in Sakhalin basin.
 Reviewed current lithology definitions in basin models, proposed tighter relationships with
petrology and wider geology, tested and demonstrated the significance of a more detailed
approach, builded rock properties database. Tested existing predictive models for rock density
and thermal conductivity, developed hypotheses for discrepancies between models and
measurements, set up experimental and student intern program to test these hypotheses and to
address deficiencies in existing calibration data sets. Stimulated and advised development of
corporate database.
 Designed and demonstrated a workflow accounting for lateral stress in sediment compaction in
basin models and for reservoir quality prediction. Applied to existing basin model from NW
Borneo.
 Reviewed petroleum systems associated with impact structures. Designed a project and
supervised an MSc student (Univ. Utrecht) to test some related hypotheses.
 Built several prospect- to basin-scale basin models in Santos and Campos basins during 6-month
cross-posting in Brazil exploration team in 2006, and a basin model for the NE Brazil to French
Guyana exploration project in New Ventures Exploration team during 6-month posting in 2009.
 Assessment of novel exploration plays - hydrates ‘05, impact craters ‘04-06, abiogenic
hydrocarbons ’09-10, cooperation with academia
