Carboxylates and their derivatives for improved hydrocarbon recovery and geological storage of hydrogen and carbon dioxide
Problem Water injection, also called “water flooding,” is the most widely used method to increase production from oil reservoirs. It usually follows the primary produc­tion stage, in which the oil production relies on the reservoir’s natural energy. One of the main factors that affect the efficiency of water flooding is the wettability...

Subsurface velocity estimation by a full waveform inversion method
Problem An important application of the geophysical inverse theory is seismic full waveform inversion (FWI), where seismic data recorded at the surface, sea floors or in boreholes is used to estimate subsurface parameters. In FWI problem, one tries to minimize an objective function that measures the misfit between observed data and estimated data with...
