Context & Assumptions

This economic model assists process engineers in performing front-end engineering design (FEED) to justify capital expenditure for extraction technology upgrades. By normalizing annual operating costs against total oil production, it provides a clear metric for comparing the operational efficiency of continuous versus batch processing systems.
