Featured R&D Activities - DIC


Data Conditioning and Faults & fracture Analysis

Seismic attributes often provide a quick way to visualize the trends of faults and fractures, which are not visible in seismic amplitude information. These set of information from different seismic attributes can be used to delineate fault geometry, and further it can be used to optimize well locations.

In this project the delineation of faults and fractures is demonstrated using an optimum workflow. Out of all the attributes tested, polar dip being a directivity driven parameter that enhances the edges and sharpens the fault to the best extent. For analysis of the fractured zones, mean curvature has brought out the most momentous results. The seismic images thus produced are complementary and are the best result produced by integration and implementation of filters and different attribute sets.


Channels &Thin Sand Delineation

GERMI developed workflows for seismic data conditioning, spectral blueing and log data conditioning to suit for inversion studies to obtain optimal results. The study resulted in delineation of channel prospect in the area.

Seismic inversion for acoustic impedance gives the acoustic impedance variation for characterization of the reservoir. Variations in acoustic impedance can be interpreted to find the low impedance area for hydrocarbon exploration.

Seismic Spectral Bluing (SSB) is a technique to optimize the vertical resolution of seismic spectrum using well information, without boosting noise to an unacceptable level. SSB analyze the seismic and well log spectra to define a Seismic Spectral Bluing operator that shapes the average seismic trace spectra to smooth curve which is representative of band limited reflection coefficient curve fit at every frequency. It results into a seismic data with enhanced frequency content and realistic amplitude data .


Multi Attribute Analysis for Delineation of Channels

Impedance Inversion studies and well property prediction was performed from well logs using an Artificial Neural Network (ANN). An ANN creates a nonlinear mapping between a set of input data and target outputs. The nature of this nonlinear mapping depends upon the type of artificial neural network used. A feed forward back-propagation neural network is used in this study to predict well log properties from Inversion results and multiple attributes.
