Rosneft Oil Company | 7/2015 – 9/2019

SENIOR RESERVOIR ENGINEER

Contributed to the implementation of Rosneft Joint Venture (JV) technical projects in Venezuela. Accountable for leading the JV team, providing reservoir engineering assessments in integrated subsurface teams, engaged with geoscientists, engineers and production operations specialists. Supported the business plan and reserves evaluations in accordance with PRMS and SEC regulations.

Key Projects/Assignment:
Oil Production potential evaluation for new well trajectories, sidetracks, and inter-pad wells for Cerro Negro field. | Drilling radius estimation for inter-well spacing for Cerro Negro field. | Dynamic model evaluation for water injection feasibility in Jobo Member. | Dynamic model and history match assessment for Alturitas field. | Dynamic modeling, history match, forecasting and uncertainty analysis evaluation for San Jose field. | Dynamic model evaluation for development plan and well status conversion for Boqueron field.

Key Accomplishments:
• Increased EUR in more than 15% by executing dynamic modeling assessment for over 250 horizontal well trajectories, including new wells, sidetracks, infills, interpads and new spacings to determine well potential production and economics.
• Evaluated the technical feasibility of disposal water reinjection to reduce infrastructure operational costs in more than 10 MMUSD, while preserving formation integrity via numerical simulation scenarios and fracture pressure analysis.
• Implemented extensive reservoir engineering studies such as dynamic model building, well test analysis, history match, production profile forecasts and uncertainty evaluations to identify parameters that impact the project performance.
• Delivered asset business plan evaluation by providing inputs on drilling portfolio, well service schedule and depletion plan as well as reporting of results to the upper management.
