PROFESSIONAL WORK HISTORY

PETROBRAS AMERICA INC., Houston, Texas 2012- June 2016

Senior Reservoir Geologist, Reservoir Group, Gulf of Mexico

Performed the 3D static model on Chinook field (Walker Ridge) Ultra Deep Water Gulf of Mexico, Lower Tertiary on Wilcox reservoir, include structural and properties models, leading to the upscale for simulation studies.

Accomplishments

Developed Wilcox reservoir and worked as a team player in order to integrate the 3D geological data to use for reservoir simulation. Evaluated the uncertainties reserves on production and exploration.

Performed the Geological wells prognosis (water depth of 8600 feet) to reach the turbidities of Wilcox reservoirs, production wells from 10M to 20M BOPD.
