Mineral scale formation is a problem for oil and gas operators that can result in deterioration of
assets, increased lifting costs and lost production.1 Scale which forms in or at the perforations
can only be prevented by placing scale inhibitor in the producing formation via some type of
reservoir displacement technique commonly referred to as a squeeze. Operators desire
inhibition that will last as long as possible and minimize the production interruption for
treatment. In reservoir formation types that exhibit known scaling problems, scale inhibition
treatment can be initiated during the completion stage using a solid inhibitor integrated into the
hydraulic fracturing program. Treatments of this type can result in deep reservoir placement of
inhibitor without large amounts of introduced water frequently needed with traditional squeeze
treatments. Data presented in this paper illustrate the superior performance and longevity of
these types of treatments.
