ABSTRACT

Three versions of the University of Calgary's (FRP and CREWES jointly) overthrust physical model.

physical_model

the physical-model data This is the data we got from (University of Calgary - FRP and CREWES jointly) We got permission from them to include it in this distribution. If you use this data in a publication you should let them know about it beforehand and properly acknowledge them.

This is the data used in the abstract: Prestack depth migration in TI media: examples with numerical and physical modeling data, Dai, Cheadle, and Isaac, GeoTriad convention 1998 abstracts, pages 83-84.

elastic

Amoco's synthetic elastic finite-difference version of their model. Mike O'brien calculated this model using a fully elastic 2D finite-difference modeling program of John Etgen's. Sam Gray and Bertrand Duquet provided the model dimensions and parameters.

This data was used in the abstracts: Anisotropic true-amplitude migration, by Fei, Dellinger, Murphy, Hensley, and Gray. GeoTriad convention 1998 abstracts, pages 85-86, and SEG abstracts 1998 pages 1677-1679.

acoustic

Amoco's synthetic ISOTROPIC acoustic finite-difference version of their model. Mike O'brien calculated this model using an acoustic finite-difference modeling code of John Etgen's, using the P-wave velocities of the corresponding elastic model. (It uses the velocity normal to the layering in the anisotropic parts.) This version of the model, calculated using a single velocity and an acoustic code, is of course isotropic.

For some unknown reason in this version of the model the reflector at the base was left out.
