Multiple is one of noise that contain on marine seismic data recording. Some seismic data processing techniques can eliminate multiple like predictive deconvolution and radon transform, but these method still has limitations, <br /> <br /> <br /> especially on water bottom multiple. One of technique to eliminate the water bottom multiple is SRME technique. Surface Related Multiple Elimination (SRME) is a method to remove multiple energy that generated by the air-water boundary (surface-related multiples). SRME is a multiple attenuation techniques to suppress multiple associated with the surface in the marine environment. This technique does not require any subsurface information but predicts multiple of the data. Multiple predicted through an iterative convolution process which utilizes a physical relationship between the primary and multiple reflections. Multiple then adaptive subtracted from the input data. This study begins with understanding the theory of multiple. Multiple on synthetic and real data has applied. Synthetic seismic modeling of marine (contain multiple) using Tesseral2D software. Synthetic models are then processed using <br /> <br /> <br /> SRME techniques to suppress multiple. Further processing SRME technique was applied to the data field Banggai Ocean, Sulawesi. SRME application of synthetic and real data shows that in the domain of shot gather, semblance velocity analysis and stacking has been reduced even <br /> <br /> <br /> multiple surfaces. For amplitude analysis, amplitude value decrease after using the SRME method.
