CHARM: Characterization of Reflectors and Modeling (UBC)
In this project we decompose imaged reflectors in pre-/post-stack data and well, core and outcrop data into dictionaries consisting of parameterized basis functions. By selecting the best fitting basis functions information is obtained on the location, sharpness, characteristic scale and instantaneous phase of the transitions from seismic images as well as from direct (outcrop), in situ(well/core) and controlled experimental sedimentary data. This information is used (i) to constrain geological models for the depositional system (permeability) and diagenic processes (porositiy); (ii) as input for rock-physical mixture models that predict sharp transitions in the elastic modulias a function of a slowly (on the length-scale of the seismic wavelength) varying composition/sorting.
