Material balance analysis is an interpretation method used to determine original fluids-in-place (OFIP) based on production and static pressure data. The general material balance equation relates the original oil, gas, and water in the reservoir to production volumes and current pressure conditions / fluid properties. The material balance equations (MBE) assumes tank type behaviours at any given datum depth - the reservoir is considered to have the same pressure and fluid properties at any location in the reservoir. This assumption is quite reasonable provided that quality production and static pressure measurements are obtained. This method is based on the premise that the pore volume of a reservoir remains constant or changes in a predictable manner with the reservoir pressure when oil, gas and/or water are produced. This makes it possible to equate the expansion of the reservoir voidage caused by the withdrawal of oil, gas and water-minus the water influx. In the present day situation, reservoir simulation is used as a more efficient tool compared to simple MBE for accurate estimation of reserve, field development and performance prediction, still MBE is used as a quick tool for various purposes for its simplicity and ease of use.

It can provide an estimate of initial HC in place. MBE is independent of geological interpretation and can be used to verify volumetric estimates

It determines the degree of aquifer influence

It is useful in the understanding of the “drive mechanism”

It helps to estimate recovery factor and recoverable reserves Thus, uses of it includes

as a precursor to reservoir simulation

to identify undrained hydrocarbons

Can be used as a forecasting tool in certain situations

Can be used to help evaluate operating strategies such as new wells,

accelerated rate, compression

In some cases, it can be used to screen for enhanced recovery
