“…The general purpose multiple prediction GSMP™ 3D multiple attenuation method (Dragoset et al, 2008) does not require regular sources and receivers. Processing synthetic and real coil data with GSMP proved that surface-related multiples can be successfully attenuated (Buia et al, 2010). The results obtained from common-shot migration of randomly sampled data for node acquisition show that common-shot WEM migration does not require prior regularization.…”

“…As Buia et al (2010) describe in their case study of a coil survey offshore Indonesia, coil data sets provide both challenges and opportunities to the data-processing geophysicist. Many of the lessons learned from that effort apply to offshore Brazil, but we have both different challenges due to a different geophysical environment and new opportunities due to the availability of new technologies.…”

With a string of recent discoveries in the pre-salt areas in deep-water offshore Brazil, this hydrocarbon province has proven to be of global importance. The pre-salt reservoirs, however, present many challenges for exploration. In this paper, we describe the acquisition and processing of a fullazimuth towed-streamer seismic survey designed for presalt exploration offshore Brazil. We show that this solution overcomes many of the pre-salt exploration challenges to provide high-quality reservoir information in an efficient manner.

“…This additional azimuth information allows for a improved constraint for the full multi azimuth tomography to produce a detailed velocity model with higher degree of accuracy. Although the Coil recording produces a high density of irregular fold, offset and azimuth distribution, after careful spatial regularization in earlier processing (Buia et al, 2010), we were able to sector the full azimuth dataset into 29 offset groups, and three 60 degree wide azimuth groups for migration velocity analysis and azimuthal tomography velocity model building. Figure 1 shows the multi azimuth workflow.…”

The Tulip 3D is a full azimuth single vessel Coil shooting survey in Indonesia. Coil geometry acquisition records a dataset with a wide range of source to detector azimuths. Amongst the numerous benefits of extended azimuth sampling methods is the advantage of illumination diversity. This has a desirable impact with tomographic velocity model building for depth imaging. The broad range of source to detector azimuth information allows an additional constraint on the travel time tomography by providing a network of intersecting rays not available with narrow azimuth geometries.
