profile modification

1. n. [Well Completions]
The process of controlling undesirable water production from a well by conducting treatments to prevent coning or cresting. A range of treatment options is available for profile modification applications, most of which are designed to reduce the permeability of the water-bearing zones to encourage preferential flow from the oil-bearing formation. The injection of polymers, or similar chemicals, that form a rigid gel within the formation matrix is a common treatment.
