Description
Julio Herbas Petroleum Engineer with extensive experience in design and operation of Enhanced Oil Recovery projects in light oil, heavy oil, gas and condensate reservoirs; lead the design, implementation and operation of thermal, waterflooding, gas flooding, solvents, and chemical flooding projects in Latin America, Europe, Africa, and Asia, working for national and international operators as Lagoven s.a. PDVSA, Shell International, BP, Total, Statoil, Maersk and Tullow Oil, and with research institutes and universities in Venezuela, United Kingdom, Germany, China and USA. Among his main EOR projects are Steam flood in Cerro Negro and Jobo fields, Low Salinity Waterflooding and Miscible Gas Injection in the Furrial field the largest oil reservoir in Venezuela, Polymer, and low salinity waterflooding Uganda, and other studies in North Sea fields.
This course is designed to provide a solid knowledge of the Fundamentals of the Enhanced Oil Recovery Process being applied worldwide to increase the oil recovery. The lectures include theoretical and practical components describing the Thermal, Chemical, Miscible, Immiscible and Hybrid methods to enhance the oil recovery and screening techniques to select an EOR Method. The participants will be exposed to practical application experiences and field examples and will have the opportunity to discuss their own cases.
