The slowness surfaces of the qP, qSV andSH wave, as well as the ray paths in these two media were also estimated.Although only the simplest situations are discussed, this paper is useful as a first step in understanding thefractured media, because it contains examples, software routines, and a reviewing of the basic concepts andformulas of wave propagation 2006 artículo científico 0122-5383 https://www.redalyc.org/articulo.oa?id=46530203 en http://www.redalyc.org/revista.oa?id=465 CT&F Ciencia, Tecnología y Futuro application/pdf ECOPETROL S.A.
