Diversion and fluid additives are crucial for fluid placement, damage removal, and effective formation dissolution while protecting well infrastructure. Effective diversion optimises the distribution of stimulation fluids to maximise production gains. Fluid additives protect tubulars, reduce friction, avoid unwanted reaction products, enhance acid performance, and aid in cleanup. This session will explore best practices and state-of-the-art techniques for diversion and fluid additives, highlighting innovative and cost-effective solutions. Case studies from global carbonate reservoirs will illustrate best practices, common pitfalls, and strategies to overcome field challenges, providing practical insights for enhancing stimulation performance.
