Additional costs due to well ageing
Pore space in the gravel pack diminishes and the amount of water entering the well decreases during the production time.
Additional energy is required to overcome the flow resistance in the annular space and in the screen slots.
A 10% drop of yield can already be a sign of an advanced stage of well ageing. The earlier a well rehabilitation is carried out, the lower the cost and the better the result.
