Note:

This formula estimates oil well productivity based on reservoir and well conditions.

• k (Permeability): Determines ease of fluid flow in the rock formation.
• h (Thickness): The height of the producing formation.
• Pe & Pw (Pressures): The difference drives fluid movement.
• Bo (Formation Volume Factor): Adjusts for expansion effects.
• μo (Oil Viscosity): Higher viscosity slows flow.
• re & rw (Radiuses): Defines the drainage area.
• Sf (Skin Factor): Indicates well performance (damage or enhancement).

Real-life Applications:

Used in petroleum engineering to estimate production rates, optimize well design, and plan reservoir management.

Conclusion:

The inflow equation is crucial for predicting well performance, guiding economic decisions, and improving oil extraction efficiency.
