With the increasing size of the seismic data volumes, machine learning applications have been found to accelerate the discrimination of seismic facies used in the identification of geologic patterns, defining stratigraphy and the direct indication of hydrocarbons. Many practitioners have demonstrated the application of dimensionality reduction tools such as principal component analysis and independent component analysis, or clustering techniques. Some of these are available in several commercial interpretation software packages.

In the world of oil and gas, an increasing number of plays in stratigraphic traps are being made – in large part due to ever-evolving seismic technology. The Discovery Thinking forum at the annual IMAGE conference in August served to highlight some of these plays in offshore frontier basins and the role that geophysics played in their discovery. “We are seeing more giant stratigraphic fields, and seismic is the key,” said past AAPG President Charles A. Sternbach, chair of the Discovery Thinking forum. “And, we are seeing more oil found at greater depths. Unconventional plays are migrating outside of the Western Hemisphere.”

In June of 2020, I set out to hike just the first 470 miles of the Appalachian Trail. Less than two weeks into my adventure, I thought to myself, “What the heck, why not do the whole thing?” It was then that I decided to hike the entirety of the nearly 2,200 miles that summer. I later decided that I would also write a book about it. “Rocks, Roots and Rattlesnakes” is that story of my daily adventures, as written from a geologist’s perspective.

The war between Russia and Ukraine has seen several phases since the initial invasion in February. A series of advances by the Ukraine armed forces in the Eastern part of the country in early September created the impression that the conflict might be near an end. Russian annexation of four provinces at the end of the month convinced others that the war is far from over. What is not debatable, however, are the devastating effects that the war continues to have, particularly on Ukrainian refugees who fled hundreds or thousands of miles to escape the turmoil and seek safety for themselves and their families. This is the second in a two-part series about Ukrainian geologist refugees who fled their homeland and received assistance from colleagues living around the world, which shares the stories of other geoscientists who benefitted greatly from the funding but still struggle to find stability after having their world turned upside-down.

A 15-kilometer-wide asteroid hit the planet 66 million years ago, ending the Cretaceous Period. It wiped out 99 percent of all life and 75 percent of all species of life on Earth. If we were to discover another such a threat coming from space today, what could we do about it? NASA's Double Asteroid Redirection Test launched Nov. 24, 2021 from Vandenberg Space Force Base in California. The DART spacecraft was built and is operated by the Johns Hopkins Applied Physics Laboratory under NASA’s Planetary Defense Coordination Office.

Natural disasters worldwide, public debate, policy decisions and shareholder pressure are just some of the factors motivating companies to seek alternatives to traditional oil and gas to fuel the ever-increasing demand for energy worldwide. One of those alternatives is hydrogen – a renewable energy source that proponents believe brings a wealth of opportunities and challenges. Argentina’s national energy company YPF is one such proponent. They are considering using natural gas from the massive Vaca Muerta play to produce “blue hydrogen,” which is produced by combining natural gas and steam.

Presented by Kevin C. Hill, Associate Professor, University of Melbourne Gravity modelling of Australia's southern margin reveals that the initial rift with Antarctica was beneath the current Ceduna Delta. A regional, high-quality seismic traverse from the coast to oceanic crust across the Bight Basin has been assembled and interpreted in detail, then balanced, restored, decompacted, and replaced at paleo-water depths. The Late Cretaceous Ceduna Delta developed above a Late Jurassic-Early Cretaceous rift basin in three stages punctuated by significant pulses of uplift and erosion across areas >100 km wide and with up to 1 km of erosion. The Cenomanian White Pointer delta prograded into deepening water and hence underwent gravitational collapse. This was terminated in the Santonian when the Antarctic margin was pulled out from below, thus supplying heat to a remnant thicker outer margin crust, causing doming and erosion. Importantly, this established the saucer-shaped geometry of the Ceduna Delta that persisted throughout its development, so that any hydrocarbons generated in the southern half of the basin would have migrated towards this outer margin high. The Tiger Formation was deposited in shallow water in a full rift basin prior to breakup, which was followed by regional thermal subsidence. The Hammerhead delta developed on the newly formed passive margin but was terminated by another pulse of uplift and erosion, perhaps associated with a change in plate motion at the end of the Cretaceous. The finite element modelling of this proposed tectonic evolution will test its validity and predict hydrocarbon generation and migration through time.

DL Abstract

Paleozoic North America has experienced multiple mountain building events, from Ordovician to Permian, on all margins of the continent. These have had a profound effect on the resulting complex basins and their associated petroleum systems. Subsequent uplift, erosion and overprinting of these ancient systems impedes the direct observation of their tectonic history. However, the basin sedimentary records are more complete, and provide additional insights into the timing and style of the mountain building events. In this study, we employ ~90 1D basin models, ~30 inverse flexural models, isopachs, and paleogeographic maps to better understand the Paleozoic history of North America.

Local sea-level changes are not simply a function of global ocean volumes but also the interactions between the solid Earth, the Earth’s gravitational field and the loading and unloading of ice sheets. Contrasting behaviors between Antarctica and Scotland highlight how important the geologic structure beneath the former ice sheets is in determining the interactions between ice sheets and relative sea levels.

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.

President Biden has laid out a bold and ambitious goal of achieving net-zero carbon emissions in the United States by 2050.  The pathway to that target includes cutting total greenhouse gas emissions in half by 2030 and eliminating them entirely from the nation’s electricity sector by 2035. The Office of Fossil Energy and Carbon Management will play an important role in the transition to net-zero carbon emissions by reducing the environmental impacts of fossil energy production and use – and helping decarbonize other hard-to abate sectors.

DL Abstract

As oil and gas exploration and production occur in deeper basins and more complex geologic settings, accurate characterization and modeling of reservoirs to improve estimated ultimate recovery (EUR) prediction, optimize well placement and maximize recovery become paramount. Existing technologies for reservoir characterization and modeling have proven inadequate for delivering detailed 3D predictions of reservoir architecture, connectivity and rock quality at scales that impact subsurface flow patterns and reservoir performance. Because of the gap between the geophysical and geologic data available (seismic, well logs, cores) and the data needed to model rock heterogeneities at the reservoir scale, constraints from external analog systems are needed. Existing stratigraphic concepts and deposition models are mostly empirical and seldom provide quantitative constraints on fine-scale reservoir heterogeneity. Current reservoir modeling tools are challenged to accurately replicate complex, nonstationary, rock heterogeneity patterns that control connectivity, such as shale layers that serve as flow baffles and barriers.

VG Abstract

The carbonate sequences that were deposited in the now exhumed Tethyan Ocean influence many aspects of our lives today, either by supplying the energy that warms our homes and the fuel that powers our cars or providing the stunning landscapes for both winter and summer vacations. They also represent some of the most intensely studied rock formations in the world and have provided geoscientists with a fascinating insight into the turbulent nature of 250 Million years of Earth’s history. By combining studies from the full range of geoscience disciplines this presentation will trace the development of these carbonate sequences from their initial formation on the margins of large ancient continental masses to their present day locations in and around the Greater Mediterranean and Near East region. The first order control on growth patterns and carbonate platform development by the regional plate-tectonic setting, underlying basin architecture and fluctuations in sea level will be illustrated. The organisms that contribute to sequence development will be revealed to be treasure troves of forensic information. Finally, these rock sequences will be shown to contain all the ingredients necessary to form and retain hydrocarbons and the manner in which major post-depositional tectonic events led to the formation of some of the largest hydrocarbon accumulations in the world will be demonstrated.
