Subsurface reservoirs are used for various applications driving the energy transition towards zero-carbon energy. Making optimal use of subsurface reservoirs is a great challenge for society these days. Geological CO2 and hydrogen storage can play a significant role in modern energy transition. However, accurate modeling of gas injection applications in deep subsurface reservoirs is a challenging task. First, the simulation framework should include complex physical phenomena, i.e., thermal-multiphase-chemical flow. The computational models depend on many uncertain reservoir parameters and imprecise measurements which require a significant number of forward modeling runs for performance optimization or risk assessment. For that, the modeling process should achieve the required level of accuracy, robustness, and efficiency. To satisfy these requirements, we are going to utilize the Operator-Based Linearization (OBL) and drift-flux multisegment techniques. OBL is the advanced parametrization technique allowing to translation of the governing physics of complex flow and transport processes into multi-dimensional tables representing the physical terms in governing partial differential equations. A drift-flux multi-segmented well approach allows to representation of realistic multi-phase flow in the wellbore and surface facilities which can be directly coupled with the flow in the reservoir. Using these two methods, we extend our Delft Advanced Research Terra Simulator (DARTS) to accurate modeling of well-reservoir interactions which play a significant role in the security of CO2 and H2 reservoir storage. 

Need to have:

• Programming in Python and C++;
• Experience in Reservoir Simulation;
• Some undertanding of thermodynamics.

Nice to have:

• Experience in Operator-Based Linearization (OBL) approach;
• Experience in wellbore modeling tools (e.g., OLGA);
• Experience in scientific writing.
