The internship project focuses on developing a 2D solver for fluid flow in porous media as a simplified reservoir model. The solver will be based on the boundary element method (BEM), offering an efficient approach for simulating flow without the need for full volumetric discretization.

An important aspect of the project is enabling the solver to handle embedded elements, such as wells and fractures, which play a critical role in controlling flow behavior. The scope includes implementing the core solver, extending it to represent these embedded features, and validating the results on simplified test cases. This work will provide the intern with hands‑on experience in scientific computing, numerical methods, and reservoir modeling, while contributing a practical tool for exploring innovative simulation techniques.

• Contribute to the extension of an existing 2D boundary element solver for fluid flow in porous media.
• Add support for embedded elements such as wells and fractures, ensuring that these features are correctly represented in the simulation.
• Implement the new functionality, test it on simple cases, and document the results.
• Deliver an extended solver prototype, validation of results.
• Create a technical report.

Through this project, the student will gain valuable experience in numerical modeling, scientific programming, and applied mathematics. They will also learn how to incorporate physical features like wells and fractures into simulation tools, and how simplified reservoir models can be used to study complex subsurface behavior. By the end of the internship, the student will have hands‑on experience enhancing a solver that connects theory, coding, and reservoir applications.
