Everyone knows Greenland has oil. But the exploration areas are so frontier they make Dodge City look like the middle of Manhattan, and so far no one has caught a glimpse of commercial Greenland production. So who will be first?

Area-wide lease sales, inaugurated in 1983, provided the oil industry an opportunity to explore for oil and gas in the deep water Gulf of Mexico, a southern extension of the oil-rich offshore Louisiana shelf province.

New computer programs were designed by Shell Oil during that decade to measure seismic amplitude changes and pay thickness, and -- most importantly -- seismic data was being calibrated with petrophysical data.

This is the first of three articles on the application of 'bright spot' technology, which helped Shell Oil Company discover many large oil and gas fields in the Gulf of Mexico during the late 1960s to the late 1980s.

In 1977 Rio del Rey is viewed as an area with a future of small fields by Elf and Royal Dutch/Shell; however, Shell's international divisions (Pecten) reports it to be a 'meadow of bright spots.'

DL Abstract

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.

DL Abstract

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.

VG Abstract

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.
