This document discusses the challenges of processing "opportunity crudes", which are crude oils available at discounted prices but are more difficult to process due to properties like high acidity, viscosity, and metal/salt content. It notes that India imports over 80% of its crude oil needs and will increase dependency to over 50% by 2030. Processing opportunity crudes requires strategies to prevent corrosion and degradation, additional investments in upgrading equipment, and increased operating costs. While financially attractive due to lower prices, opportunity crudes require careful planning to process profitably and ensure energy security for refiners.
