Basic Economics of Chemical EOR spreadsheet

We this spreadsheet, you will get a clearer and structured approach to evaluating the economic feasibility of polymer flooding and other chemical EOR methods with this three-sheet spreadsheet. It provides a basic yet accurate estimate of total costs, helping you rank candidate projects, build stronger scenarios, and make informed decisions about implementation.

What’s Inside?

🔹 Sheets 1 & 2 – Focus on polymer flooding (PF), surfactant-polymer (SP), and alkali-surfactant-polymer (ASP) methods. These sheets intentionally omit the time value of money, allowing you to quickly estimate costs based on pore volume, oil in place, polymer cost, and injection rate. By adjusting concentrations and injected volumes, you can model total project expenses. While the duration of oil recovery remains uncertain, the model conservatively assumes that once polymer injection stops, water breakthrough will end the project—defining its economic lifetime.

🔹 Sheet 3 – Introduces basic production profiles, adding a time factor to the equation to enhance long-term planning and forecasting.

This tool is perfect for early-stage evaluations, offering a practical way to assess cost-effectiveness before diving into detailed simulations.

✅ Quickly estimate OPEX & CAPEX
✅ Compare and rank EOR candidates
✅ Refine project assumptions with basic scenario modeling

The following videos take you through the different sheets and explain the inputs required, outputs and how you can use the numbers to build a basic business case.
