Crosshole transmission tomography a method to locate ore bodies by crosshole measurements. Fig. 1 is redrawn from his original paper (Fessenden 1917). It is a plan view showing four vertical boreholes and two ore bodies in between. Using a source of seismic energy in one of the boreholes and a detective device in one of the others,

Tomography from seismic profilesofile, cross-hole, etc.). It may be applied to surveys of various scales (local, regional, DSS, etc.). It allows simultaneous usage of various types of waves (refracted, reflected, transformed). An outline of the structure of the program package is offered and both model and field data examples are

Innocence

Seismic rock properties for reservoir descriptions and monitoringdistribution of interfaces between rock types within the earth, but also about the mineralogy, and the state of the subsurface rocks. In fact much of our knowledge about the internal . of the earth has been derived from seismic wave characteristics such as velocities and amplitudes.

嘴唇可修剪

Seismic data collection platforms for satellite transmissionwaves as possible, in order to extract an evenly distributed information. For global seismological studies, we are concerned with wavelengths larger than one kilometer. We will not consider the specific problems related to the oil industry. The industry has already performed tomographic experiments

Surface wave holographysts of two steps. First, from surface wave recordings, dispersion data (phase velocities or group velocities) are retrieved for each source receiver pair (Dziewonski and Hales, 1972; Nolet, 1977). Next, the information for different frequencies and many source receiver pairs is combined to yield an
