Computers have taken on more and more of the load in seismic interpretation. But advances in computational seismology and the use of seismic attributes won’t remove the geologist from the equation.

Touted as a “revolutionary” fault-imaging attribute, Thinned Fault Likelihood (TFL) is proving to be a relatively new and successful tool for revealing sweet spots and fracture proximity in highly faulted formations, said AAPG member Hesham Refayee, a geoscientist at dGB Earth Sciences.

The main goal for shale resource characterization is usually the identification of sweet spots, which represent the most favorable drilling targets. Such sweet spots can be identified as those pockets in the target formation that exhibit high total organic carbon (TOC) content, as well as high brittleness. As there is no direct way of computing TOC using seismic data, we adopt indirect ways for doing so.

The calibration of seismic data with the available well control is an important step that provides the link between seismic reflections, their stratigraphic interpretation and subsequent prediction of reservoir and fluid properties.

AAPG is the largest geoscience organization in the free world, and its members know more about frontier areas now being explored than anyone else. Part of our scientific responsibility is to act as advisers, not advocates for one political stand – either for or against climate change. AAPG needs to be part of the conversation.

We present a simple workflow that allows an interpreter to more accurately extract such attributes using the volumetric calculators available in most commercial interpretation software packages.

A team of structural geologists and seismic processing geophysicists has developed what they believe is a potentially revolutionary technology that can help predict fracture performance before a well is ever drilled.

The often-volatile outcome of exploration investment decisions is tightly linked to the level of uncertainty in the geological interpretation and associated value assessment. In order to evaluate subsurface opportunities, information is needed.

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.

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.
