How Do We Improve the Productivity Index?

 This can be done by altering the parameters in the flow equation. Thus, for the well

productivity or inflow performance to be improved, we need to carry out any of the

following:

• Acid stimulation to remove skin

• Increasing the effective permeability around the wellbore

• Reduction in fluid viscosity

• Reduction in the formation volume factor

• Increasing the well penetration
