Machine Classification of Pore Space for Hydrocarbon Reservoir Characterization

Abstract

From the position of hydrocarbon storage, pores of oil-bearing rocks are divided into three groups: pores contained relatively large oil-patches (industrial reservoirs), pores contained small percentage of oil (nonindustrial reservoir) and others. The reservoir rocks have complex chemical and mineralogical compositions. This paper defines the algorithm classifying heavy-oil-bearing reservoirs, based upon physicochemical properties of rock which are related to the pore and fluid distribution. The impact of these properties had been investigated separately and in relation, one to another, particularly as they pertain to the detection and evaluation of hydrocarbon-bearing layers.
