Abstract:

In the petroleum exploration and production, building 3D geological model, in recent years, has become one of the indispensable tools to help evaluate the petroleum potential of a field. The objective of it not only to calculate oil and gas reserves, but more important is to simulate the spatial distribution of the reservoir, calculate accuratelt oil and gas reserves in place of the reservoir, allow multiphase fluid flow simulations, provide information for the need of the field management and development. But, in fact, the geological characteristics of the oil and gas fields are generally very complex and heterogeneous, so that building of 3D geological model of the reservoir is becoming more difficult. To construct the geological model of the layer in details with high accuracy, the identification of flow units associated with sedimentary rocks and creating proper porosity - permeability relationships plays an important role. This paper presents a summary of the results of the 3D geological model based on identification and modeling of flow units for in the Lower Mioxen reservoirs, White Tiger oilfiled, Cuu Long basin that is located in the continental shelf of Vietnam
