“Geologists and geophysicists work well together.” That’s Stephen A. Sonnenberg on why AAPG and the Society of Exploration Geophysicists will be coming together for the International Meeting for Applied Geoscience and Energy at the Colorado Convention Center in Denver and online, Sept. 26 through Oct. 1. This year’s inaugural hybrid event will include nearly 200 technical presentations, 14 workshops, 10 special sessions, five field trips, numerous networking opportunities and a joint exhibition showcasing the latest geoscience products and technologies will be on hand.
The International Meeting for Applied Geoscience and Energy, or IMAGE ’21, the integrated annual convention of AAPG and the Society of Exploration Geophysicists in conjunction with the Society for Sedimentary Geology, is all set for its inaugural event to be held online and in-person in Denver, Colo., Sept. 26 to Oct. 1. This gathering of the industry’s top thinkers, leaders and innovators boasts an impressive schedule of special sessions, workshops, field trips and other offerings to expand geoscience and professional skills.
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.
As commodity prices have dropped, many shale plays have become uneconomical as statistical plays and have increasingly become recognized as geological plays demanding new insights from data.
Henry W. Posamentier discusses the application of 3-D seismic stratigraphic analyses to the mitigation of risk associated with lithology prediction prior to drilling – workflows and techniques. Principles and workflows of seismic stratigraphy and seismic geomorphology will be discussed and numerous examples will be shown from a variety of different depositional settings.
The Eagle Ford Shale in South Texas is one of the more exciting shale plays in the United States at the current time.
Join two GIS/geoscience experts Scott Sires and Gerry Bartz as they use information from the Teapot Dome Field in Wyoming (DOE/RMOTC program).
Gas hydrates, ice-like substances composed of water and gas molecules (methane, ethane, propane, etc.), occur in permafrost areas and in deep water marine environments.
There are approximately 1,000 oil and gas fields in the world that have been classified as 'giant,' containing more than 500 million barrels of recoverable oil and /or 3 trillion cubic feet of gas.
This esymposium takes a close look at workflows associated with resource plays, and analyzes where integration must occur between disciplines, data, and workflows at all phases of the process.
This course is ideal for individuals involved in Midland Basin exploration and development. Successful development of Wolfcamp shale oil relies on complex inter-relationships (ultimately interdependencies) within and between a wide variety of scientific disciplines, financial entities, and company partnerships.
Effective hydraulic fracture stimulation is critical for shale development, and microseismic is the only technology able to map the growth of these hydraulic fracture networks.
This e-symposium presentation places the interpretation of deep-water turbidites discernible in 3-D seismic inversion data within a geological context.
The following short course option was developed for geology and geophysics students that have not had much exposure to how geoscience is applied in industry. It can be tailored for undergraduate juniors and seniors or graduate students. The agenda can be modified to meet specific needs and time constraints. Contact the presenter to discuss options.

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.
