Résumé / Abstract

This paper presents a field case study of a reservoir in the Orinoco Oil Belt, Venezuela. The reservoir is a heavy oil accumulation of 10 degrees API gravity, with about 2.5 billion of STOIP. It has been produced for about 12 years by more than 170 wells, 25% of them horizontal. Due to high oil viscosity, almost all vertical wells have been producing under cyclic steam stimulation; no steam has been used in horizontal wells. A special formulation for modelling the so called foamy oil behavior has been used, supported by laboratory tests and theoretical considerations. Additionally, a control volume finite element (CVFE) grid was used to construct a simulation model, which was history matched and used for production forecasting and economical evaluation.
