Cyclical effects on heterogeneous oil reservoirs

The essence of the method of cyclic influence and change of the direction of fluid flows is that in the layers with heterogeneity in the size of pores, the permeability of layers, interlayers, zones, areas and their uneven oil saturation (flooding) caused by these types of heterogeneity, as well as the selection of oil and water injection through discrete points - wells, artificially creates unsteady pressure.
