Abstract Horizontal well is an important way to develop thin reservoir with edge-bottom water aquifer. For the horizontal near oil–water contact, have features of edge and bottom at same time. The productivity formula in pure or not fully applicable this type reservoir. heterogeneous composite aquifer, divided into multiple sections by using concept multi-segment well. Based on seepage mechanic...

Reservoir models with many grid blocks suffer from long run time; it is hence important to deliberate a method to remedy this drawback. Usual upscaling methods are proved to fail to reproduce fine grid model behaviors in coarse grid models in well proximity. This is attributed to rapid pressure changes in the near-well region. Standard permeability upscaling methods are limited to systems with ...
