Investigation of Inflow Performance Relationship in Gas Reservoirs for Vertical and Horizontal Wells

Adel Moh. Salem Ragab


Horizontal wells have been applied all over the world because of their high productivity. The well performance of these wells has not been well-defined yet. Therefore, the main objectives of this study are to evaluate the well performance of horizontal wells and compare it to that one of vertical wells.


Using the same drainage areas and similar fluid properties, the well productivity and Inflow Performance Relationship (IPR) for both vertical and horizontal wells are evaluated and compared for steady-state flow of compressible and incompressible fluids. Current models for both types of vertical and horizontal wells are evaluated to stress their strengths and weaknesses. The replacement ratio of horizontal well to vertical well are calculated. Furthermore, a sensitivity analysis are performed on common variables to compare and evaluate vertical and horizontal well flow equations
