“…When studying accidental gas release relevant for the oil and gas industry, the current authors failed to capture the jet transition with an Eulerian two‐fluid model. Thus an Eulerian‐Lagrangian modelling concept was developed . In this concept, gas bubbles are treated as Lagrangian particles and their motion is coupled to the water phase via the drag force in the momentum equation.…”

In this paper we review the current understanding of bubble plumes discharged from subsea sources related to oil and gas production, and show how CFD can be applied for risk assessments. A general introduction to causes and risks is given. This is followed by a discussion of the physics that need to be accounted for before giving a brief review of the different modelling approaches employed today. The empirical and experimental knowledge base is also summarized. An example of how CFD can be applied to study gas releases is given. At the end we outline what is needed to advance current understanding of such releases and model their interaction with the surroundings. The scope of the review is limited to the fate of the gas and the flow induced by the ascending bubble plume in the water column. Atmospheric dispersion of surfacing gas is not considered.

“…We have previously carried out high‐flow‐rate single‐well CO 2 blowout simulations for onshore and offshore wells without analysis of attenuation by the water column. Researchers at Sintef (Norway) have developed and demonstrated a sophisticated computational fluid dynamics (CFD) simulator of gas blowouts into the water column applicable to major CO 2 blowouts . Sintef researchers have also written a comprehensive summary of the state of understanding of offshore gas release that covers both natural gas and CO 2 systems …”

Growing interest in offshore geologic carbon sequestration (GCS) motivates evaluation of the consequences of subsea CO2 well blowouts. We have simulated a hypothetical major CO2 well blowout in shallow water of the Texas Gulf Coast. We use a coupled reservoir‐well model (T2Well) to simulate the subsea blowout flow rate for input to an integral model (TAMOC) for modeling CO2 transport in the water column. Bubble sizes are estimated for the blowout scenario for input to TAMOC. Results suggest that a major CO2 blowout in ≥50 m of water will be almost entirely attenuated by the water column due to CO2 dissolution into seawater during upward rise. In contrast, the same blowout in 10 m of water will hardly be attenuated at all. Results also show that the size of the orifice of the leak strongly controls the CO2 blowout rate. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd.
