Contaminant transport in porous media is often modeled by solving the Advection Dispersion Equation (ADE) which describes way contaminant moves within bulk fluid as well movement of due to phase. The simulation can however prove be computationally expensive especially if medium discretized into high-resolution grid blocks. We propose an interwell model for advection dispersion equations (ISADE) predict concentration observed at pumping well. This method comprises two main steps. Initially, divides aquifer or reservoir a series 1D injector-producer pairs and uses historical observation data estimate five major unknowns each these control volumes: connectivity, pore volume, volumetric flowrate face, coefficient, number grids volume. Finally, once history matching process complete, estimated variables are used wells. Five example cases were studied results show that ISADE was able with reasonable accuracy observed. Furthermore, easily handle changes input parameters such contaminants released aquifer, injection production rates.
