Chemical EOR simulation study of a compositional flow and their stability.

Modern techniques have revolutionized the capability of enhanced oil recovery (EOR) software to mimic the behaviour of complex reservoirs. This study incorporated this concept into a 3-dimensional reservoir model to execute chemical EOR techniques and analyze their stability. The analysis included assessing factors like thickness, permeability, injection rate, and flooding patterns to quantify incremental oil recovery. The study involved constructing a reservoir model for waterflooding and comparing it with polymer, surfactant, and alkaline-surfactant-polymer (ASP) floodings. The results showed that chemical EOR techniques yielded oil recovery increases ranging from 5% to 18%. Among the sensitivity analyses, ASP flooding with a higher injection rate stood out, achieving the highest oil recovery rate at 92%. While flooding patterns and permeability had directly influenced oil recovery, the impact of reservoir thickness on incremental oil recovery was relatively small but significant.
