Explorer Foundation Update

Ahmed Ismail, a passionate geoscience educator who not only showed potential but also sensed a career calling as early as grade school, has been named this year’s recipient of the AAPG Foundation’s Inspirational Geoscience Educator Award. Ismail, who has international experience in academia, the energy service sector (Schlumberger) and with the Illinois State Geological Survey, is an assistant professor at the Boone Pickens School of Geology at Oklahoma State University, where he has taught since 2016.

The AAPG Southwest Section Convention explored a four-dimensional multiverse of geology and reservoirs, combining regional overviews with multi-scale measurements of rocks and sediments, and analyzing rocks in the fourth dimension of geologic time. The result is “Resology,” which general chair Ben Davis defines as “the study of geology and rock reservoirs at big and small scales.” He told conference attendees, “The goal of Resology is effective and efficient hydrocarbon production.”

The September 2021 Geophysical Corner was an article entitled ‘3-D Visualization and Geobody Picking of Amplitude Anomalies in Deepwater Seismic Data,’ in which we reviewed the use of geobody tools to rapidly visualize the extent of geologic features that give rise to a strong seismic amplitude response. For seismically thin reservoirs, the response of a gas-saturated sandstone gives rise to a trough at the top and a peak at the base. In this case, we would need to select two separate geobodies to map the reservoir.

Explorer Historical Highlights

There are two main oil and gas producing sedimentary areas in France: the Paris Basin and the Aquitaine Basin. The presence of oil seeps and bitumen deposits has been known since ancient times in the western part of the Aquitaine basin, a 35,000-square-kilometer triangular polygon bordered to the north by the city of Bordeaux, to the east by Toulouse and to the south by the Pyrenees Mountain chain separating France from Spain. These hydrocarbon shows were observed close to surface anticlinal structures such as the Sainte-Suzanne dome, southwest of Pau or in the caprocks of salt diapirs at Salies de Bearn and Dax to the north.

Phase decomposition is an interesting technique that can decompose a composite seismic signal into different phase components, and which in turn can help with the characterization of thin target sandstone or carbonate reservoirs. Here we discuss the application of phase decomposition as a reservoir management tool, with the odd phase component (sum of plus 90 degrees and minus 90 degrees phase components) showing better correlation with the wells that control the injection and withdrawal of a natural gas storage reservoir in Denmark.

For Colombia’s National Hydrocarbon Agency and national oil company Ecopetrol, now is the perfect time to seek opportunities in a country providing diverse geological potential, a prepared workforce and contractual stability. They believe that Colombia is that country, and they are prepared to make their case as principal sponsors and hosts of AAPG’s International Conference and Exhibition taking place in Cartagena April 19-22.

Crossplotting is widely used in AVO analysis because it facilitates the simultaneous and meaningful evaluation of two attributes. Generally, common lithology units and fluid types cluster together in AVO crossplot space, allowing identification of background lithology trends and anomalous off-trend aggregations that could be associated with hydrocarbons. Interactive crossplots allow the interpreter to visualize the relationship between different well log properties or between different seismic attributes.

Shell has made a significant oil and gas discovery at the Graff-1 well offshore Namibia. The well results have so far shown at least two reservoirs in the Upper Cretaceous, with a light oil column reported in the Santonian, in high quality channel sands. This discovery is in the deep water of the southernmost sector of the Orange Basin offshore Namibia.

Phase decomposition is a novel technique that decomposes a composite seismic signal into different phase components, which can improve reservoir characterization. The technique is particularly useful in those areas where thin-bed interference causes the phase of the input seismic response to differ from the phase of the embedded wavelet in the data.

The estimated hydrocarbon reserves around the world, when produced, can keep us going for the next several decades. But scientific records and our own experiences are enough evidence that climate change is indeed happening. Addressing it requires energy extraction from non-fossil fuels. One such resource is the natural heat of the Earth, or geothermal energy.

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.
