Development of artificial neural network models to calculate the areal sweep efficiency for direct line, staggered line drive, five-spot, and nine-spot injection patterns

•Areal Sweep Efficiency for direct line, staggered line drive, five-spot, and nine-spot injection patterns.•Development of artificial neural network models to calculate the areal sweep efficiency more accurately than the previously published correlations.•Establishment of a new artificial neural network model for calculating the areal sweep efficiency for the nine spot injection pattern, as there is no current model to calculate it.•Facilitate the calculations of oil recovery during waterflooding operations.
