Downhole scale inhibitor squeeze treatments and monitoring have been performed for several years at the Kuparuk River Field (KRF) as part of an overall scale inhibition program. This paper discusses the evolution of these treatments during the past two years. During this period, the diesel-based preflush used to prepare the reservoir rock for adsorption of the scale inhibitor has been replaced by an aqueous-based preflush. This has resulted in reduced costs by replacing the diesel with water and by reduced equipment and manpower requirements for each treatment. In other testing, it was determined that there was no benefit from the shut-in period, which followed the second overdisplacement of the treatment.
