4D seismic history matching: Assessing the use of a dictionary learning based sparse representation method
Soares, Ricardo; Luo, Xiaodong; Evensen, Geir; Bhakta, Tuhin (Journal article; Peer reviewed, 2020-12)It is possible to improve oil-reservoir simulation models by conditioning them on 4D seismic data. Computational issues may arise related to both storage and CPU time due to the size of the 4D seismic dataset. An approach ... -
Sequential multilevel assimilation of inverted seismic data
Nezhadali, Mohammad; Bhakta, Tuhin; Fossum, Kristian; Mannseth, Trond (Journal article; Peer reviewed, 2023)We consider estimation of absolute permeability from inverted seismic data. Large amounts of simultaneous data, such as inverted seismic data, enhance the negative effects of Monte Carlo errors in ensemble-based Data ...
