Saudi well study derives optimal gas well configuration parameters

Zillur Rahim Adnan Al-Kanaan Hamoud Al-Anazi Saudi Aramco Dhahran A study of Saudi gas wells led to quick and simple analytical solutions for determining well geometries that improve productivity. This article covers the effect on reservoir productivity from such factors as reservoir permeability, vertical anisotropy, net pay thickness, horizontal well length, fracture half length, fracture conductivity, number of finite transverse fractures induced in a horizontal wellbore, and other relevant parameters. Although the results obtained from the analytical solutions are somewhat optimistic because they do not consider damage or operational issues, the results are a reference to assess quali...
