Paper presented at the SPE Reservoir Simulation Conference, March 25–27, 2025
Paper Number: SPE-223892-MS
... Abstract Subsurface CO 2 sequestration is a promising method to advance carbon neutrality and support the shift toward sustainable energy. However, the unique behavior of CO 2 in these operations, particularly for cold CO 2 injection in depleted hydrocarbon reservoirs, poses challenges...

Paper presented at the SPE Reservoir Simulation Conference, March 25–27, 2025
Paper Number: SPE-223893-MS
... Abstract This study presents a novel framework for simulating compositional two-component, two-phase CO 2 sequestration models by integrating the Enriched Galerkin (EG) discretization scheme with a phase-field formulation. Traditional equation of state (EoS) compositional models often face...

Paper presented at the SPE Reservoir Simulation Conference, March 25–27, 2025
Paper Number: SPE-223902-MS
... Abstract In this work, we present a thermal-compositional simulation framework for modelling of CO 2 sequestration in de- pleted hydrocarbon reservoirs. The parametrization technique utilizes thermodynamic state-dependent operators expressing the governing equations for the thermal...

Paper Number: SPE-223922-MS
... Abstract The SPE11 comparative solution project presents a benchmark for geological carbon storage in an aquifer, as the development of sufficiently accurate CO 2 sequestration models is critical for predicting the distribution of CO 2 during and after injection. In this paper we present...

... to the consideration of CO 2 dissolution in oil, the conventional B-L equation is modified to a concentration balance equation, without the effects of phase compressibility and gravity segregation. Then the front velocity of CO 2 can be expressed in fractional flow: At the core of PINNs is the idea of embedding...

Paper Number: SPE-223839-MS
... The pressure and temperature conditions for CCS in depleted oil and gas reservoirs can be close to the saturation and critical conditions of CO 2 . This gives rise to numerical complexities in reservoir simulation as pure or low-impurity CO 2 is a narrow boiling fluid that is known to yield...

..., utilization, and storage (CCUS) scenarios, it is essential to account for the dissolution of CO 2 and certain light hydrocarbon components in the aqueous phase. Throughout this paper, unless explicitly stated otherwise, no special distinction is made between hydrocarbon components and water. Governing...

... impermeable. In this work we extend the idea of pressure jump stabilization to the compositional poromechanics setting in order to suppress these spurious oscillations. We apply this method to simulations of CO 2 injection into a synthetic aquifer which is represented using a fully unstructured mesh...
