Abstract
This paper presents the results of a study conducted to estimate the petro physical and reservoir rock properties. Petro physics highlights those properties relating to the pore system; its fluid distributions and flow characteristics. These properties and relationships are used to evaluate hydrocarbon reservoirs, hydrocarbon sources, aquifers and seals. The reservoir and fluid characteristics to be determined are: Lithology of the area (rock type), fluid saturations, pressures, fractional flow (oil, gas and water), permeability (absolute), porosity, fluid identification characterization and thickness (bed boundaries). It is simple to distinguish these features and to value their part in the calculation of reserves. The difficult part comes in determining their real value at a level of assurance required to make economic decisions leading to development and production. The seven characteristics listed are interdependent (i.e., to properly determine porosity from a wire line log, one must know the lithology, fluid saturations, and fluid types). The knowledge of petro physics is then used to interpret the hidden world of rocks and fluid properties of reservoir from subsurface to a depth ranges up to four miles deep.
