The model divides the reservoir into blocks that represent locally homogeneous substructures of the reservoir and couples the analytical, pressure-transient solutions at the block boundaries. This approach is consistent...

This method overcomes the standard limitation of the conventional IE method related to the use of a horizontally layered background only. The new IE method still employs...
