| Abstract | |
Most proven conventional oil reserves in the world are contained in carbonate reservoirs, which mostly of them have fractures that impact on reservoir dynamic behavior. These discontinuities well-known as fractures are found in nature on several scales and, depending on theirs size, they can present many difficulties to be characterized and modeled mathematically. As an example that can be mentioned is the intrinsic complexity of subseismic fractures characterization to model objects on a smaller scale than the scale of seismic and well data. Overall, fractures have always been a challenge because of various reasons like the increasing in computational time simulating or the difficulties faced to characterize them. These concerns are related to the fact that most of the engineering studies are already complex, iterative and consume large time until its conclusion as, for example, the history matching process. In order to assist and reduce the time spent on these studies is proposed to build a fast tool able to select models through the use of the theory of Graphs, before leaving directly to costly fractured reservoir simulations. Thus, it is developed a methodology of connectivity analysis between wells and also between well and all reservoir, which is based on the representation of reservoir models by Graph theory and the use of its algorithms. This methodology is employed in four different applications: (1) initial selection of static models, (2) validation of the relationship between connectivity and breakthrough time, (3) to assist the history matching process and (4) for improving the sweep efficiency (AU) | |
