Petrophysics
Pore Pressure & Frac Gradient Prediction / Detection

My expertise includes hydrocarbon maturation (Team Leader, Assurance, Petrophysicist) of a multitude of experiences in the deepwater in the Americas from exploration through mature development via a significant career at Shell. I have a strong experience base to call from in order to guide an optimum development concept and to review the complete volume story for integrity.

I have a deep technical understanding in the creation and use of pore pressure fracture gradient, wellbore stability, and fault re-activation estimates, and robust knowledge of what is needed for translation to an optimal well design. Most importantly, I draw from experience to actively influence sound, critical decisions during drilling operations. That experience includes 100+ wells drilled in the DW environs of the Northern GoM (Mars, Ursa, Brutus, Great White, Ram Powell, Auger), Mexico, Trinidad, Brasil (presalt and subsalt), Eastern Seaboard of Canada, and the Chukchi Sea (AK).

My team leadership experience spans 10+ years including BHP and includes SS teams moving volumes from exploration success to development execution and Petrophysics teams concentrating on mature developments in the USGoM DW, into my last role at Shell where I had a Petrophysics team of 2 sub leaders and 20 staff in total. The remit there was to cover the maturation and execution of 90% of all wells drilled in the DW Americas, exploration and development.
