Water coning in petroleum reservoirs leads to water breakthrough and significant alterations in the oil production profile, severely impacting well productivity and recovery rates.
The retrieved literature consistently supports the claim that water coning alters production profiles by causing water breakthrough, rapid water cut increases, and significant drops in oil productivity. Papers [0], [6], and [8] all explicitly address how coning changes field production data, recovery dynamics, and well performance. No papers refute this widely established reservoir engineering principle.
