Seismic Data Processing involves a critical part in the investigation of oil and characteristic gasses. In the course of the most recent two decades the computational prerequisites of the SDP exercises have grown up numerous folds because of the expansion in the information volume and also the advancement in the scientific calculations. Three dimensional information securing has gotten to be normal as it has ended up important to take a gander at the minor points of interest of the underground geography.
Wave condition based strategies are of increasing prominence as of late as they give better point by point geographical components than other traditional techniques and they safeguard

ω - x seismic relocation is a propelled method in light of wave condition and uses limited contrasts. It has a few points of interest over ordinary strategies as it deals with sidelong speed varieties, can endure bigger speed blunders, exact up to 70 degrees and can deal with plunges up to 90 degrees. Be that as it may, it is computationally extremely concentrated. The movement calculations in ω - x area are innately parallel as far as frequencies. This favors us to respond to the call of exceptional process serious nature of ω - x movement on a parallel design …show more content…
Just the required number of frequencies are put away after Fourier change. The recurrence band width to be utilized for relocation is resolved from unearthly investigation of the info follows. This structures the info information to the profundity movement code. Notwithstanding this an appropriate speed profundity model is likewise required. The parallel usage is practically equivalent to Master-Worker framework. Subsequent to perusing all the required parameters, the Master decides the quantity of frequencies and recurrence data transfer capacity to be allotted to every Worker. At that point it peruses and sends the recurrence information to the assigned Worker. At that point the relocation calculation goes through the profundity steps. The required speed information for that profundity step is sent to the Workers. Additionally, the moved information from every one of the Workers for that profundity is gathered by Master, imaged and put away on the circle. A stream outline of this calculation is appeared in Figure 1. The figure just shows one Master assignment and one Worker undertaking, however as a general rule there are numerous Worker errands. All the Worker undertakings speak with Master assignment in an indistinguishable manner as appeared in the figure
