Oil and gas production needs energy, sufficient enough to drive the produced hydrocarbon to the surface of the well. Usually some of this required energy is supplied by nature. The hydrocarbon fluids are under pressure because of their depth. The gas and water in petroleum reservoirs under pressure are the two main sources that help move oil to the well bore and sometimes up to the surface. Depending on the original characteristics of hydrocarbon reservoirs, the type of drive energy is different. The material balance equation has been a very useful tool in analyzing these mechanisms. If none of the terms in the material balance equation can be neglected, then the reservoir can be described as having a combination drive in which all possible sources of energy contribute a significant part in producing the reservoir fluids, and determining the primary recovery factor. For this to happen, the water must be produced from an aquifer. The aquifer water expands slightly, displacing the oil or gas from the reservoir towards the borehole as pressure drops around the borehole. Most literatures have been able to call attention to the analysis of strong and partial water drive. This study was able to bring to light the aquifer characteristics based on weak water drives. Knowledge of the cumulative water influx is also important to the reservoir engineer. This study also goes ahead to add to aquifer detection and characterization, the cumulative water influx of each reservoir. The whole process entailed analyzing reservoirs A,B,C and D using the method proposed by Cole and Campbell. The plots showed a weak water drive for all reservoirs. The water influx for all the reservoirs were calculated and results obtained. The Cole and Campbell plots were proven to be more accurate method of detecting and characterizing aquifer and water drive strength.
