.... 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...

.... Signal processing is performed on all of the acquired data to distinguish acoustic signature of any possible leak or flow events from background acoustics. Annular pressure manipulation workflow is performed sequentially altering pressure in different conduits in isolation and therefore helps to identify...

... a pilot study to assess the viability of passive 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...

Source signature variations create artifacts in predicted multiples due to spatial discontinuities. Variations from a well-behaved...

.... Three different sonar responses were observed: (1) more-or-less uniformly high BS, (2) high BS center surrounded by lesser BS halo ( bulls-eye and (3) high BS with an acoustic dead spot near the center.
