... floor with high backscatter in water depths of ~1500 m over the Barbados Accretionary Complex. The relationship of seafloor morphologic features such as faults, craters, and mud volcanoes with vent-gas plumes in the water column is indicative of substantial emissions from this region. Disappearance...

... Abstract A 3D seismic, AUV and geotechnical data integration has been conducted in order to assess the potential impact of a large Mud Volcano (MV) activity and its related mudflows for subsea field development. The studied area is located within the South Caspian Basin (SCB). The tectonic...

... of the first PSA contract area wide integrated geohazard study that addressed the threats of individual sources of geohazard to Full-Field Development planning. These included, amongst other issues: slope instability, mud volcano stand-offs and fault risks, all being included in the first integrated geohazards...

... rates of the detected bubble streams. The goals of this work are to quantify the volume flux emanating from natural seeps found on salt domes and mud volcanoes in the Gulf of Mexico. A combination of acoustical and optical tools was used for this purpose. The sonar used for this work was a forward...

... Abstract Multiscale seabed seepage manifestations are identified on high-resolution geophysical datasets in an area of the South Caspian Basin and compared with seepage features at the Dashgil mud volcano, onshore Azerbaijan. Features identified range from small-scale gas seepage mounds...

... in buried structures (Pilcher et al., 2007). The analysis of buried structures (fault systems, channels, mass transport deposits, mud volcanoes) is important to detect pockmarks and to understand their origin. It exists another type of pockmarks related to the presence of gas hydrates (Sultan et al...

... Abstract MultiBeam Echo Sounder (MBES) bathymetric and backscatter data are used to discriminate the backscatter response of four seafloor features: a carbonate mound, a hydrate mound, a small mud volcano, and pockmarks in the vicinity of the welldocumented Bush Hill seep site. Each...

..., sand-rich channel axes, drowned carbonate reefs, mud volcanoes, and chemosynthetic seeps have been sampled throughout the program. This catalog demonstrates that backscatter can be calibrated by cores to specific processes, and thus that multibeam backscatter is a robust tool for constraining geologic...

... Abstract The signal to noise problems inherent in towed streamer data associated with mud volcanoes, subsurface heterogeneities and distributed gas in the Azeri, and Gunashli structures of the Caspian sea prompted the use of three dimensional four component ocean bottom seismic (3D/4C OBS...

... Abstract The geohazard assessment for Block 1 identified multiple geohazards in the field development area. The most significant of these hazards are active faulting, mud volcanoes, shallow gas and earthquakes. Less dramatic but equally important features identified were seabed ridges...

.... Ensuring platform stability problems through avoiding sub-sea mud volcanoes is another such application. The foundation of chimney processing is based on the meta-attribute concept that will be briefly highlighted. Chimneys are also used for exploration of hydrocarbon targets both in high grading prospects...

... in southeastern offshore Azerbaijan is defines the areal distribution of mud volcanoes and allows for their classification based on characteristic seismic features. As a result, a detailed database for each mud volcano is constructed. A high concentration of mud volcanoes is observed at the southern part...

It has been suggested that shelf and slope sediments of high deposition rate are methane sources, whereas the deep basin is methane sink. Slope failures and sediment instability are serious...
