▪   Basin Systems & Reservoir Quality Modeler | 2019 – 2020

I integrated the work of exploration teams with other subject matter experts to predict in 4-D petroleum maturation, migration, accumulation, volume, and phase behavior. Using Zetaware products, this work primarily served global offshore exploration and provided probabilistic outcomes for risking and resourcing. As the company’s primary resource in reservoir quality modeling, I predicted clastic porosity and permeability and collaborated with the engineering disciplines to estimate reservoir deliverability.

▪   Exploration Geologist | 2015 – 2019

I worked as a member of an interdisciplinary team accumulating deep experience evaluating the petroleum systems of the Mesozoic and Cenozoic Gulf of Mexico, Falkland Basins (North, South, & Plateau), Canadian Orphan Basin, and especially the pre- and post-salt of the greater central Atlantic West African margin. I lead or assisted numerous aspects of the planning, drilling, and geological evaluation of several high-impact deepwater wells in these basins.

▪   Pore Pressure Specialist | 2014 – 2015

I utilized the Eaton and Bowers methods to build vertical profiles of pore pressure and its derivatives at offset wells. Extrapolating these to 3-D volumes of seismic velocity in the Mesozoic and Cenozoic Gulf of Mexico, I built regional volumes of pore pressure and its derivatives to predict petroleum migration and accumulation, under-compacted reservoir sands, subsurface drilling hazards, and prospect well and mud program design.

▪   Development Geologist | 2013 – 2014

I mapped fluvial channel sands of the Cheng Dao Xi oilfield (offshore Bohai Bay, China) in 3-D seismic and well log section. Re-interpretation of existing correlations lead to improved fit with production data and multiple new development leads.
