When the AAPG/AAPG Foundation initiated the Imperial Barrel Award, there was a sense that participating students would take the unique experience with them and pay it forward. Which brings us to AAPG member Elizabeth Hajek, assistant professor for Penn State University.

When it comes to providing students “real-world” experience in the classroom, some schools stand out more than others. Consider the University of Kansas, where one interdisciplinary course teams geoscience and petroleum engineering students to analyze live data from partnering oil companies.

Having first examined the post-stack and prestack methods of seismic impedance inversion (May and June 2015 EXPLORER), we now end the three-part series by turning our attention to joint inversion of multicomponent data.

Integration and creative thinking were recurring themes in the 2015 Discovery Thinking forums held at the AAPG Annual Conference and Exhibition (ACE) in Denver last month.

Explorer Historical Highlights

This is the story of the drilling of a costly ($60 million) Lahee A-1 well in the Colombian foothills, which presented significant deviations from the prognosticated stratigraphy halfway to the objective – and became an operational nuisance. Nonetheless, it is mainly a story of successful management and prompt response to the geological uncertainty.

In last month’s Geophysical Corner `we described the different poststack impedance inversion methods that are available in our seismic industry. In poststack seismic inversion – where there is no mode conversion at normal incidence – it is purely acoustic. P-wave impedance is the only information that can be estimated from poststack inversion of P-wave data.

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.

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.

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.
