Bs. Rathor et al., APPLICATION OF FINITE-DIFFERENCE METHOD IN MODELING ON OIL-BEARING STRUCTURE, Journal of the Geological Society of India, 47(1), 1996, pp. 23-28
Finite-difference numerical technique has been in use for over two dec
ades in solving elastic wave equation for the interpretation of seismi
c response of complex 2-D and to a limited extent, 3-D oil bearing geo
logical structures. The present communication consists of two parts. I
n the first part, synthetic seismograms have been obtained under plane
wave as well as line source excitations for a gas cap structure and o
ver a salt dome/basement undulation. In the second part, seismogram un
der plane wave conditions has been computed for a geological structure
from the Gujarat coast. Some of the faults confining the pay zone bet
ween 1800 ms and 1900 ms in the time section are highlighted.
