Volumetric Method of Reserves Estimation

The volumetric method of reservoir is a very simple and yet elegant mathematical tool that gives a fairly accurate idea about the volume of hydrocarbons in the reservoir. Its accuracy depends upon a correct estimation of certain physical properties of the reservoir viz. Porosity , Reservoir thickness .

In the simplest mathematical terms , the volume is determined as 

Where , V is the volume of the hydrocarbon in reservoir
              A is the area over which the reservoir is spread
              h is the thickness of the reservoir
              phi is the reservoir porosity
              Swc is the connate water saturation
              Bo is the formation volume factor
