Modern reservoir engineering relies heavily on simulation models to provide a reliable prediction of the subsurface petroleum system. An ideal reservoir simulation model is one that represents the main features and behavior of a real system, but is simple enough to perform calculations in an efficient manner. -- Using compressibility and transmissibility concepts, multiple reservoir tanks and flowing wellbores can be coupled to provide wellbore influx and inter-tank fluid transfer. This creates a series of ordinary differential equations that, when solved, can be used to describe the system's pressure and fluid movement pattern. This work uses these ordinary differential equations are efficiently solved using the Fourth-Order Runge-Kutta technique. -- A flexible system of equations was created to represent 'n' number of communicating reservoir tanks which were then solved using ordinary differential equations for the first time. -- This work demonstrates the successful integration of aquifers, reservoir tanks, well inflow, and wellbore modeling into an integrated system that can quickly be used as a tool for investigating petroleum systems. This work can form a fundamental module enabling the calculation of coupled wellbore and reservoir models with advanced completion technologies.
