Technical Abstract

Full broadband processing including total Q compensation in the presence of gas

Back to Technical Content
We propose a broadband processing workflow that is purely data driven and applicable to both conventional towed and variable depth towed marine streamer data. Three important ingredients of our workflow are highlighted: (1) deghosting; (2) FS-QTomo and A-QTomo; (3) prestack depth Q migration (Q-PSDM). We first demonstrate through a simple synthetic example how FS-QTomo can benefit from the removal of source and receiver notches in obtaining more accurate Q field. We then utilize a field data example from offshore Malaysia that exhibits severe absorption resulted from gas pockets to show how our workflow can preserve the fidelity of amplitude, frequency and phase of the data.
