Remote evaluation of the mobility characteristics of a fluid enclosed in the pores of subsurface rocks is an issue of the major interest in the petroleum industry. In a last decade several techniques to perform such an evaluation based on attributes derived from seismic images have been proposed. Although these techniques have foundation in theory and have delivered results of reasonable quality in...
In exploration geophysics, one of the major techniques of estimating the properties of the EarthpsilaS subsurface is reflection seismology. In this method, a seismic source of energy - wideband pulses produced by dynamite or a specialized air gun, or a narrow band chirp signal - is used to send waves into the earthpsilas interior. An array of receiver - typically geophones or hydrophones - suitably...
This work describes a technique for segmentation of multiple logs to obtain common boundary. A principal component analysis is applied to further improve computation efficiency by exploiting inherent correlation among various measurements. A develop statistical approach for automatic termination of the algorithm is planned; that is, to have a priori estimation of number of final segments.
