Overall, machine learning has introduced us to a whole different world that has taken geoscientists by surprise. However, the real question is how much can we trust the machine? How accurate can it be? And the most intriguing question of all – can machine learning replace the interpreter? We will analyze three machine learning processes to assess the pros and cons of utilization of convolutional neural networks for fault prediction versus interpretations made by the user in a highly complex polygonal fault section of a 3-D seismic reflection dataset.

Blending of seismic attributes with additive primary colors is a standard visualization procedure used by interpreters to integrate the information contained in them and carry out comprehensive interpretation. In the December 2019 and February 2020 installments of Geophysical Corner, we described how color is perceived by the human eye, and how colors are rendered on interpretation workstation monitors. We also described the additive RGB color model which forms the working model for computer monitors, as well as the subtractive CMYK model and the HSV and HSL color models frequently used for covisualizing seismic attributes.

Analog traps are an important part of any geoscientist’s tool kit, and there is no better source than understanding how giant fields form and have been found by past and current generations of explorers. My sojourn into learning about these big fields was in the mid-1980s at Amoco in Denver, part of a task force charged with understanding how to better explore for big, subtle, stratigraphic and combination traps. Meeting weekly for lunch for several months, a team of us reviewed Amoco’s proprietary “Red Book” – a collection of summaries of giant fields worldwide, which included maps and rock properties, but, more importantly, the strategy used in finding each field. In addition, we pulled heavily from AAPG giant fields publications compiled from hundreds of AAPG volunteers.

Just as Alaska was bracing itself for the economic fallout of the Biden administration’s adversarial stance on oil and gas, two recent court decisions are giving the state hope. On June 15, a federal judge lifted the administration’s temporary ban on federal lease sales, clearing the way for a highly anticipated lease sale in the prolific National Petroleum Reserve – Alaska. And, on May 26, a brief filed by the U.S. Department of Justice affirmed that the Willow Project, a major discovery in NPRA that has been tied up in environmental-related lawsuits, complies with environmental regulations. While it remains unclear how soon the NPRA lease sale can take place, it is expected that the Willow project, one of the North Slope’s largest projects in recent years, will move forward.

Increasing global concern about climate change and its impact on the environment and society has led to a variety of strategies to reduce carbon dioxide emissions and to remove CO₂ from the atmosphere and find places to store it. Many companies are hard at work to perfect methods of carbon capture, use, and storage. Franek Hasiuk, associate scientist at Kansas Geological Survey, said CCUS is the best technology available to reduce emissions produced by the global economy. Hasiuk is part of a team of scientists working on the Integrated Midcontinent Stacked Carbon Storage Hub, a project to investigate subsurface geology in southwest Kansas and southwest Nebraska and demonstrate the viability of injecting CO₂ into underground rock layers.

Whatever the style of faulting, manual interpretation of faults on vertical seismic sections is traditionally a laborious and time-consuming process. Seismic attributes such as coherence, variance and Sobel filters accelerate the fault interpretation process. Fault-sensitive attributes can be further subjected to image enhancement methods such as swarm intelligence, Radon transforms, and smoothing and sharpening filters aligned parallel and perpendicular to the fault attribute anomaly. One such development is the fault likelihood attribute.

The overriding principle of AAPG’s special interest groups is to create an environment in which experienced professionals with like-minded views and concerns can come together to discuss, share, commiserate and become familiar with industry trends and Association events. Further, such groups create an environment in which individual members, including those in academia and service companies, as well as those in non-petroleum-based companies, both contribute to and benefit from programs and events of interest. The geoscience community in Kuala Lumpur, Malaysia was no stranger to the concept. For years, there was a SIG for young professionals, but the thinking was that there also needed to be something tailored for the experienced professional.

Seismic data are usually contaminated with noise, which, stated simply, refers to unwanted signal. Noise in seismic data can originate from various sources but processed seismic data may contain the following types of noise: random noise, steeply dipping coherent noise, aliased coherent noise that may appear to be random, and coherent multiples that are often subparallel to the reflectors of interest.

Since the first explorationists discovered the subsurface potential in Tunisia, the country’s institutions took the role of a partner rather than only a regulator. Today, one of ETAP missions is promoting exploration opportunities in Tunisia through both regional and targeted approaches, including sharing knowledge, high-quality data and best practices. ETAP commits to supporting continued drilling activity in mature areas and encouraging/incentivizing exploitation of new and emerging plays.

Economic oil and gas fields have been increasingly found in deep-water continental margins for the past decade, where potential prospects record the key tectonic events associated with plate breakup and continental drift. In these regions, the exploitation of economic resources must take into account sustainable practices and environmental concerns of local populations. This talk will present case studies from multiple continental margins to then extrapolate major findings to basins in SE Asia.

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.

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.
