Well, shake it up, baby: Hydro-impact technology is using seismic wave stimulation technology to shake loose residual oil trapped in the reservoirs around existing wells.
Well data isn’t the geologists only tool to assess potential of deep basins or frontier areas. Think 'source rock.'
A recent AAPG Geosciences Technology Workshop examined the contributions, challenges and responsibilities of geoscientists in estimating resources and reserves.
This month’s column deals with determining reservoir heterogeneity in Athabasca oil sands from surface seismic data.
When it comes to geothermal energy, Germany is feeling the heat – literally and figuratively – beneath its feet.
Sweet smell of success: A run of offshore discoveries have made Brazil the oil industry’s story of the century – and the celebration there may just be starting.
Seismic reflection amplitude can be related to net pay and can provide information about the presence or absence of hydrocarbons in a reservoir interval.
WEB EXCLUSIVE: A comprehensive look at the use of cutting-edge technology in Egypt’s Western Desert – including the application of new seismic, drilling and stimulation operations – helped make AAPG’s first international Geoscience Technical Workshop a big success.
Deep freeze: Cutting-edge technology, environmental awareness and a lot of warm clothing are helping seismic crews cope in hostile Arctic regions.
Urban development: Seismic crews found creative ways to complete a successful operation in the sensitive Long Beach/Signal Hill oil field.
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.

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.

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.
