The first carbonate field application of a new organically crosslinked water shutoff polymer system

摘要

This paper describes the chemistry and treatment design of the first field application of a recently developed, organically crosslinked polymer (OCP) system for water shutoff. The candidate for which this treatment was designed is a production well in the North Sea that was completed in naturally fractured chalk. Each of the completed intervals were acid fractured to further open the existing natural fractures and increase production.
