The well integrity issues to be considered in the approach to enhance oil and gas recovery using existing wells

Abstract

Approaches to enhance oil and gas recovery by artificial lift, EOR/IOR and well stimulation for existing wells have been required due to maturation of domestic oil and gas fields and decline in oil prices. However, these new approaches have not always been considered on well designs based on earlier drilling, completion and production operations and other challenges might arise later in order to maintain well integrity.
