Exploration geologists are scientists and dreamers, observers and analysts.
Ideally, seismic data should be acquired at high spatial and temporal sampling, so that the small subsurface features of interest can be clearly seen on the seismic display.
The ultra-deepwater Alaminos Canyon area proved to be a valuable lease purchase in the recent Gulf of Mexico Lease Sale.
This article introduces a new set of seismic attributes that play an important role in extracting detailed stratigraphic information from seismic data.
Sometimes the best seismic data acquisition system for a job is a combination of two.
Seismic acquisition crews in southwest France attempt to gather data without disturbing the locals.
Canadian crews survey Christchurch faults, receive enthusiastic support from local governmental agencies.
The quest to establish a commercially viable thermogenic petroleum system in the Tobago Basin continues.
Major 'Caribbean plate' survey by Moscow-based consortium 'Geology Without Limits' to commence soon, will bring together leading scientists from around the world.
New technology breathes life into older seismic data acquisition and processing methods.
In comparison with the known boundary conditions that promote salt deformation and flow in sedimentary basins, the processes involved with the mobilization of clay-rich detrital sediments are far less well established. This talk will use seismic examples in different tectonic settings to document the variety of shale geometries that can be formed under brittle and ductile deformations.

Three-dimensional (3D) seismic-reflection surveys provide one of the most important data types for understanding subsurface depositional systems. Quantitative analysis is commonly restricted to geophysical interpretation of elastic properties of rocks in the subsurface. Wide availability of 3D seismic-reflection data and integration provide opportunities for quantitative analysis of subsurface stratigraphic sequences. Here, we integrate traditional seismic-stratigraphic interpretation with quantitative geomorphologic analysis and numerical modeling to explore new insights into submarine-channel evolution.

Around 170 million years ago, the Gulf of Mexico basin flooded catastrophically, and the pre-existing landscape, which had been a very rugged, arid, semi-desert world, was drowned beneath an inland sea of salt water. The drowned landscape was then buried under kilometers of salt, perfectly preserving the older topography. Now, with high-quality 3D seismic data, the salt appears as a transparent layer, and the details of the drowned world can be seen in exquisite detail, providing a unique snapshot of the world on the eve of the flooding event. We can map out hills and valleys, and a system of river gullies and a large, meandering river system. These rivers in turn fed into a deep central lake, whose surface was about 750m below global sea level. This new knowledge also reveals how the Louann Salt was deposited. In contrast to published models, the salt was deposited in a deep water, hypersaline sea. We can estimate the rate of deposition, and it was very fast; we believe that the entire thickness of several kilometers of salt was laid down in a few tens of thousands of years, making it possibly the fastest sustained deposition seen so far in the geological record.
