Lehmann B. Seismic traveltime tomography for еnginееring аnd ехрlоrаtiоn аррliсаtiоns
EAGE Publications. 2007. - 126 p.
Seismic tomography and tomographic methods in general are well established in applied geophysics, particularly for near surface applications, where high geometrical (i.e. geological) resolution and accurate values of parameters are required. These are the basis of anу reliable assessment of petrophysical parameters and lithological properties.
Though well established , useful and successful, seismic tomography still has some problems. Large scale research and development is going оп in instrumentation, lay­ out, geometries, and inversion schemes as well as petrophysical interpretation. There is а need in the seismic community and among applied geophysicistss for а snap-shot of current technology, assessing the possibilities and present limitations. This book of Bodo Lehmann serves this purpose excellently and will join the row of state of the art books about seismic tomography published in the last 15 years or so.
Thе special feature of this book is that it is based оп the huge experience Bodo Lehmann has accumulated in his career as а geophysicist in every aspect of seismic tomography, starting with field measurements and going оп to inversion. Lehmann's PhD in 1992 was already а thorough assessment of the method of "Transmission and reflection tomography" carried out at the U niversity of ВосЬит. It was supervised Ьу Lothar Dresen, well known to the community not only for the Schlumberger Award of ЕАСЕ in 1992. This study of Lehmann was based directly оп practical work, as Ье was employed Ьу WestHilische Berggewerkschaftskasse (WВK), the ancestor of the current DMT in Essen. Не is stil1 at DMT involved in refining the methods and assessing their capabilities.
