  • Three-dimensional Methods In Seismic Exploration |

    Two-dimensional seismic prospecting methods are inadequate to solve the three-dimensional geological problems that arise in petroleum exploration. The three-dimensional seismic technique is a data collection and processing system that samples the subsurface adequately. The structure and lithology of rocks are mapped accurately by imaging their acoustic reflectivity with the scalar wave equation.

  • The Determination Of The Seismic Quality

    Abstract Ten methods for the computation of attenuation have been investigated, namely amplitude decay, analytical signal, wavelet modelling, phase modelling, frequency modelling, risetime, pulse amplitude, matching technique, spectral modelling and spectral ratio. In particular, we have studied the reliability of each of these methods in estimating correct values of Q using three ...
