Post-Doc position about modeling uncertainty of plume propagation in CO2 storage

In the framework of a collaboration between the CSTJF Research Center of TotalEnergies in Pau (France) and the Geosciences Centre of the Paris School of Mines in Fontainebleau we are proposing a post-doctoral position on the subject of:

CO2 storage: reducing uncertainty on CO2 plume propagation distances and predicting their spatial footprint through Ensemble Methods

Postdoctoral position: September 2024 to August 2026 (2 years)
Location: TotalEnergies CSTJF, Avenue Larribau, 64018 Pau, France (http://cstjf-pau.totalenergies.fr/en)

CCS (Carbon Capture & Storage) is a part of a major strategy of To- talEnergies to achieve Carbon neutrality. The goal by 2030 is to develop a CO2 storage capacity of more than 10 million tons per year. To achieve this goal, significant innovation effort is necessary. This is supported by numerous multidisciplinary research projects within the R&D line “CO2 and Sustainability” of TotalEnergies Onetech. The Centre for Geosciences Mines Paris - PSL develops spatial-temporal probabilistic models, parameter estimation methods for these models, and associated prediction algorithms. The Centre also develops geochemical speciation and reactive transport codes to quantify and model coupled physicochemical phenomena.

The objective of this work is to understand the dynamics of CO2 plumes via Ensemble methods and, based on the geological and reservoir models of a storage site, to test and validate the methodology for 4D seismic data history matching on the plumes. TotalEnergies’ participation in various consortiums and partnerships for CO2 storage allows the use of data from several CO2 injection sites, notably those in Australia and in the North Sea. Relying on data from CO2 storage projects (notably 4D seismic, acquired at different times over the same area), we will seek to combine geophysical expertise, dynamic reservoir simulation techniques, and mathematical methods (i.e., Ensemble methods), to understand the dynamics of plumes in saline aquifers. We will address the problems of storage security and the role of different physical mechanisms involved in CO2 storage.

Your scope will consist of:
  • studying the static and dynamic model of CO2 injection in a saline aquifer, particularly the aspect of uncertainties associated with the input parameters and their impact on the propagation distance of the plume and its shape;
  • applying Ensemble Method (software provided) to this case study, in order to reduce the gap between the initial predictions of the CO2 plume and the observations (4D seismic) while ensuring the coherence of the geological concept.
  • based on these results, estimate the long-term movements of the plumes, as well as the impact of storage mechanisms on their stability.
