The Casablanca oil field, discovered in 1975 and located on the Mediterranean shelf edge, has been greatly significant in the world’s offshore oil industry activity, besides being by far the biggest oil field in Spain.

The University Centre in Svalbard, in the Norwegian high Arctic archipelago, has created a geoscientific database for high Arctic training and research, a unique approach to the retrieval, coordination and cataloging of data in a less than hospitable area.

Coherence and curvature attribute computations are usually carried out on stacked seismic data volumes to delineate faults, flexures and large fractures. If the vertically-aligned parallel fractures in the subsurface are filled with fluid, or weakly cemented, the P-wave velocity across the fractures will be slower than that parallel to the fractures. These differences give rise to a velocity variation with azimuth. Because impedance is the product of density and velocity, such fractures also give rise to amplitude variation with offset.

It was only expected to produce for 30 years. But now, 40 years later, BP looks forward to another 40 years of production in Alaska’s Prudhoe Bay.

Where are the best opportunities in the future for exploration investment? The central question about where to look, where to drill, which area of the world holds the greatest promise, in terms of profits, the rule going forward may very well be: “When you go low, you go high.”

An old joke used to be told in Israel: Why did Moses so unwittingly lead the Jewish people to the land of milk and honey and not to one of its petroleum-rich neighbors? Not anymore. In the last decade, giant gas fields have been discovered in the Eastern Mediterranean Sea offshore Israel, and offshore gas is rapidly becoming the main source of energy for power generation.

The challenges of the Mina El Carmen Formation can be overcome by evaluating the application of various interpretation tools and special processes, so that the reservoir sands can be detected and visualized in terms of their geometry, orientation, extension, thickness and position in the stratigraphic column.

A strategy gaining force to reduce risk and improve decision-making in recent years is “integration,” the practice of combining disparate teams to complete single projects. Integrated teams are increasingly common in the energy sector, where single business units include geologists, geophysicists, petrophysicists, engineers and other professionals who work on a common project.

Saudi Aramco hopes to push the boundaries of exploration by creating and encouraging new technologies. The company said it is pursuing the promise of “the fourth industrial revolution” through Big Data and supercomputing and investigations into nanotechnology applications.

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.
