reservoir models with many grid blocks suffer from long run time; it is hence important to deliberatea method to remedy this drawback. usual upscaling methods are proved to fail to reproduce fine gridmodel behaviors in coarse grid models in well proximity. this is attributed to rapid pressure changesin the near-well region. standard permeability upscaling methods are limited to systems with lin...

There has been intensive investigation on the understanding of liquid loading phenomenon lately via experiment and transient approach. This is driven due to limitation traditional approach using steady state Turner correlation be used over a wide range actual conditions (i.e such as under various tubing diameters, fluid condition (CGR/WGR), horizontal or deviated trajectory well) which can lead...

Abstract The development of multistage fracturing technology in horizontal wells is a great impulsion to the successful unconventional resources. hydraulic fractures distribute regularly along wellbore, forming seepage channel for fluids tight gas reservoir and greatly improving productivity wells. Based on Green function Neumann product principle, we establish flow model fractured well coupled...
