Abstract Unconventional resources, such as heavy oil, are increasingly being explored and exploited due to the declining availability of conventional petroleum resources. Heavy crude oil poses challenges in production, transportation, refining, its high viscosity, low API gravity, elevated sulfur metal content. Improving quality can be achieved through application steam injection, which lowers oil’s viscosity enhances flow. However, injection alone falls short meeting growing demand for...
