The Orinoco oil belt is one of the largest known accumulation of non-conventional oil in the world, estimated to be around 1.36 trillion barrels of initial hydrocarbons in place, with gravity ranging from 8 to 15°API. An investigation of alternative production technology processes having potential application in the giant Orinoco Beltis presented. The challenge for selecting an adequate method is to determine a relationship between reservoir characteristics and the potential of an EOR/IOR mechanism. For this purpose, screening criteria to manage available production technologies has been proposed based on geostatistical analysis and oil recovery technologies. The objective was to evaluate and rank production exploitation schemes to achieve the most attractive processes on which to pursue further work toward increasing recovery. The use of geostatistical methods and its integration with reservoir engineering enables to build a model of a process and to estimate uncertainties on the response predictions. Multiple realizations of reservoir static variables and fluid properties and correlations are used to represent reservoir heterogeneity, and uncertainty assessment and reproduce available data to be reliable. This is a useful methodology for selecting suitable production technologies, assess risks and improving know-how by comparing practical experience and probabilistic results.
