Description

Geoscientist with 20 years’ experience in the integration of diverse geological and geophysical datasets to undertake petroleum systems analyses, developing robust regional- to block-level interpretations and defining conventional and unconventional exploration prospects.  My experience covers frontier exploration, new ventures analyses and reviews, and exploitation of legacy producing fields.  This had been undertaken both onshore and offshore, including activity around the Atlantic Margin (Suriname/Guyana, Gulf of Guinea, Mauritania/Senegal, Ireland, and Brazil), US onshore, New Zealand, and the North Sea. 

I have a versatile functional experience set, including tectonostratigraphic analysis from well, seismic and other remote sensing data, seismic mapping and attribute analysis, GDE development, basin modeling, and lead and prospect development with associated volumetric and risk assessment.  I have participated in the planning and drilling of multiple offshore and onshore wells in exploration, appraisal, exploitation and development scenarios.  I am a recognized expert in structurally complex deep-water systems, with experience in depositional environments including carbonates.

I am a dynamic self-starter, able to adjust quickly to new geographic areas.  I work effectively in a cross-functional team environment, having extensive experience in collaborative inter-company and JIP projects.  I am an effective, experienced presenter to various audiences from team, to partner, to Ministerial level, and have an intermediate fluency in French.  I am also licensed as a Professional Geologist by the states of Texas and Wyoming.
