LEONARDO J. SANTANA M. PR TECH ENG

SENIOR RESERVOIR ENGINEER

MSC IN PROJECT MANAGEMENT

PERSONAL PROFILE.

Status: Married

Citizen: Venezuelan

Place and Date of Birth: Caracas, 26/10/1970

PROFESSIONAL PROFILE

Petroleum Engineer (Reservoir Engineer) with 22 years of hands-on experience in Oil and Gas Industry, with experience in Field Lifecycle Development, Well Delivery to Abandonment, Production forecasting and business planning activities using the latest technology available in multi-cultural environments. My career has been developed working in multi discipline teams as a Reservoir Engineer, with strong exposure to Integrated Reservoir Management. My main objective is adding value optimizing hydrocarbon production using technical knowledge and experience.

I have proposed field development plans in different reservoir across the world, supporting the manager in the decision-making process. I am specialist in reservoir performance monitoring, well surveillance, production allocation, reserves calculation, production forecasting, reservoir modeling, CCAL, SCAL, PVT, and data management. I can perform each of these activities using technical software (Eclipse, OFM, MBAL, PROSPER, among others). I have experience in unconventional reservoirs (tight oil and gas reservoirs, HPHT)

I also have a sounding background in reservoir management, interacting with geophysicists, geologists, specialists in petrophysics, geomechanics, geostatistics, reservoir engineers, numerical simulators, capital projects (infrastructure) and drilling. During my duties as reservoir manager I use the latest procedures approved by the Project Management Institute, including planning, execution, performance surveillance, change control and, closure of the projects.

My experience includes (but is not limited to) reservoirs in Venezuela, Argentina, Mozambique, Angola, Iran, South Africa, Ghana, Mexico and Egypt, in new and mature fields, exploration and production and both onshore and offshore. I have also applied project management workflows during planning and executing those projects, including change management, supervising and coaching engineers and technicians, adopting new methodologies and the latest technology, driving to continuous improvement.
