Hydraulic flow unit based 3D geological model of early Miocene reservoirs in Bach Ho field
Abstract
In recent years, 3D geological model has become one of the indispensable tools to help evaluate the petroleum potential of a field, simulate the spatial distribution of reservoirs, accurately calculate oil and gas reserves in place of the reservoir, and allow multiphase fluid flow simulations, thus providing information to facilitate field management and development activities. However, the geological characteristics of oil and gas fields are generally very complex and heterogeneous, that is why building 3D geological model of reservoirs is really difficult. To construct the geological model of the layer in details with high accuracy, it is important to identify the flow units associated with sedimentary rocks and create proper porosity - permeability relationships. This paper presents a summary of the results of the 3D geological model based on identification and modeling of flow units for the early Miocene reservoirs in Bach Ho field.
