Joint History Matching of Production, Tracer, and 4D Seismic Data in a 3D Field-Scale Case Study
Available to PurchasePublisher: Society of Petroleum Engineers (SPE)
Paper presented at the SPE Norway Subsurface Conference, April 27, 2022
Paper Number: SPE-209522-MS
... parameters. Among them, production data are the most used in history matching, but others also provide valuable complementary information. In this work, we take inter-well tracer and 4D seismic data as the extra sources of information for their high potentials for improving the understanding of reservoir...

Sparse Representation of 4D Seismic Signal Based on Dictionary Learning
Available to PurchasePublisher: Society of Petroleum Engineers (SPE)
Paper presented at the SPE Norway One Day Seminar, May 14, 2019
Paper Number: SPE-195599-MS
... Abstract This work presents the use of Dictionary Learning methods for a sparse representation of 4D seismic data in history matching. We consider a trade-off between the number of coefficients retained in the sparse data representation, the computational cost, and how well we can capture...
