Simulación bidimensional de reservorio aplicada a la formación Hollín mediante afloramientos análogos en el sector Centro Shaime

Abstract

The behavior of the fluid in the porous medium was analyzed using information from a similar outcrop of the Hollin formation. Samples collected and identified in the south-eastern sector of Ecuador were used in an outcrop located in Centro Shaime belonging to the Zamora Chinchipe province. A static model and a dynamic model corresponding to the Hollin formation were generated using the TNavigator software. A basic grid, distribution of rock types, petrophysical properties and a dynamic characterization of the flow in the porous medium were elaborated. Petrophysical and geological data corresponding to two outcrop study profiles were used to construct the lithofacies model. The results correspond to the simulation of the lithofacies characteristics of the Hollin formation in horizontal and vertical direction. In addition, capillary pressure data obtained in the laboratory were associated with the behaviour of the fluid based on the heterogeneity of the reservoir. The laboratory results were taken to the Hollin formation model that was generated using basic geomodelling techniques such as Kriging interpolation. The developed work constitutes a contribution in the knowledge of the flow in the formation Hollin and validates the use of samples of outcrops for this dynamic characterization of fluids.
