.... 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...

... hydrocarbon modules to function properly in real world conditions in deep waters at elevated pressures. Water depth for the pilot survey ranged from 1500 – 1700 meters. Positive thermogenic signatures were detected in the Gabon samples. A baseline (i.e. non-thermogenic) signature was also detected...

... technology was used to complement traditional geochemical analyses for this project. As seen in Figure 2, the AGI sampler contains a specially engineered oleophilic (i.e. oil loving) adsorbent that concentrates hydrocarbon signatures over a specified period of time. The result is a 1,000-fold increase...

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...
