A site characterization survey in northwestern Oman demonstrates the ability of passive geochemical sorbers to identify and map elevated hydrocarbon signatures along certain fault segments, showing that an associated reservoir was unsuitable for sequestration purposes. A CO 2 monitoring program...

Water depth for the pilot survey ranged from 1500 – 1700 meters. Positive thermogenic signatures were detected in the Gabon...

... below the surface, weak surface current signature). All surface rings presented maximum currents well above 1m/s while one ring peaked at 1.65 m/s. The subsurface ring was unique in nature as near-surface currents peaked at ~0.6m/s while the sub-surface currents peaked at ~1.2m/s. The impact of some...

... promise for modifying the source signature for conventional air gun arrays. Introduction Traditional seismic data acquired via streamers is generally deficient in frequencies below 10 hertz. Among the issues associated with low frequencies are how to record them and how to get them from the field...

... feathering. Inadequate spatial sampling causes aliasing artifacts. These can be reduced by f-k filtering at the expense of limiting the bandwidth in the predicted multiples. Source signature variations create artifacts in predicted multiples due to spatial discontinuities. Variations from a well-behaved...

We can divide the perturbations experienced in seismic into: Those that affect the received signal, such as sensor sensitivity variations and ambient noise, such as swell. Those that affect the emitted source signature, such as Shot...

The quality of the output from these deconvolution processes degrades as the pulse departs from minimum phase. An acoustic source which delivered the same acoustic signature for an indefinite period of time would...

... Abstract This new technique estimates the airgun array signature directly from marine seismic data and uses that estimate to phase compensate the deconvoluted data, followed by a bandlimiting filter matched to the estimated source signature. The array signature is simulated by a gaussian...
