On the accuracy and spatial sampling of finite-difference modelling in discontinuous models
(Journal article; Peer reviewed, 2022)Finite-difference modelling estimates the wavefield in the subsurface by solving the elastic or acoustic wave equation numerically in a discrete version of the subsurface. The derivatives in the wave equation are approximated ... -
Seismic characterization of reservoirs with multiple fracture sets using velocity and attenuation anisotropy data
(Journal article, 2011)Knowledge about the spatial distribution of the fracture density and the azimuthal fracture orientation can greatly help in optimizing production from fractured reservoirs. Frequency-dependent seismic velocity and attenuation ... -
A seismic field test with a Low level Acoustic Combustion Source and Pseudo Noise codes
(Journal article, 2007-01-20)The Low level Acoustic Combustion Source (LACS) is a new type of pulsed underwater acoustic source with an output level of 0.5-1.0 barm peak to peak. The source is based on a combustion engine and intended for shallow ...
