Abstract:
The various embodiments herein provide a method to acquire seismic data to estimate reservoir characteristics in a shallow sea water environment. According to an embodiment herein, a method comprises acquiring four component ocean bottom cable (4C OBC) seismic data using a hydrophone and a three component geophone by varying a time delay between the shots and spacing between the shots. A full acoustic modeling process and an elastic modeling process are applied to the acquire 4C OBC seismic data to acquire a pressure data and an inline geophone data to estimate a horizontal component data and a reflected shear wave data. The estimated horizontal component data are NMO corrected and stacked by varying sampling intervals to remove noise component in the acquired seismic data. A shear wave energy data is estimated from the acquired pressure data to estimate shear wave properties of a sea bed and a subsurface carbonate reservoir.
