The need for helium is growing and supplies in the United States are dwindling, creating an economic opportunity for geoscientists whose knowledge and skills are ideal for this niche industry. In Arizona, known for its helium-rich formations, a growing number of companies are leasing land and drilling for the gas.
The idea of an oil-finding instrument was not new. Water dowsers were common throughout the United States and among most people of European descent worldwide, and they were quickly adapted to looking for oil. Soon after the Drake well in 1859, people started working on inventions to detect oil by geophysical methods.
“We’re probably at least 10 times larger. I mean, it just dwarfs any other project in North America.” That’s Vincent Ramirez, CEO of 3PL Operating, Inc., talking about a large and valuable lithium discovery his company has made in Railroad Valley, Nev. As lithium will play a vital role in the world’s changing energy landscape, generally, and because much of the known lithium deposits are in Chile, Australia, Argentina and China, specifically, 3PL’s find in central Nevada is potentially a very big deal.
This year’s International Meeting for Applied Geoscience and Energy, beginning August 28 in Houston, doesn’t have a single, overarching theme. But one concept keeps popping up again and again: Innovation. AAPG and the Society of Exploration Geophysicists, in conjunction with SEPM, are hosts for the second annual IMAGE meeting. It’s designed as a broad-interest event, with 30 key topic areas ranging – alphabetically – from acquisition and survey design to structure, tectonics and geomechanics. As an AAPG/SEG-sponsored event, IMAGE will include several sessions related to geological analysis, imaging and interpretation.
With the price of oil hovering well over $100 a barrel, some in the industry are exploring ways to revisit conventional oilfields using technology that emerged during the unconventional oil boom, with a goal of earning a rapid return on investment while prices remain favorable.
Global events of recent years have driven the oil and gas industry to make major changes to its workforce and operations, and the professional and scientific associations that serve the industry have had to evolve and adapt to accommodate those changes, particularly with regard to the programs they offer. The Imperial Barrel Award competition is no exception. An AAPG staple since 2007 and one of the Association’s most prestigious and visible programs, the IBA has undergone multiple changes during the past two years.
After the past year as president of the Division of Environmental Geosciences, my three big takeaways are that the world needs energy, all forms of energy are in transition, and geoscientists are needed to explore for and develop energy – now and in the future. In every future energy scenario, oil and gas will be needed for decades at various levels to contribute to the global energy mix.
The small town of Cunningham, Kansas lies about 65 miles straight west of Wichita on U.S. Highway 54. It was incorporated in 1887 as a commercial center for farmers and ranchers in that part of south-central Kansas. Hard winter wheat was the main cash crop, while herds of beef and dairy cattle were a close second source of income. This activity characterized the culture of Cunningham into the early years of the 20th century. That is, until a new industry was introduced to Kansas when, in 1915, oil was discovered in the El Dorado field northeast of Wichita.
The challenges in acquiring quality laboratory flow measurements in very low-permeability reservoir rock samples has furthered the development of image-based rock physics simulations of multiphase transport properties. The concept of “digital rocks” originated 50 years ago and has become more widespread recently with advances in imaging technology, computing power and robust algorithms for representing complex multiphase flow behavior at the pore scale. Simulation results based on high-resolution images have the dual role of complementing laboratory measurements on conventional reservoirs and acting as a stand-alone predictive tool for unconventional reservoirs where the very low permeability values limit what can be measured in the laboratory.
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.
The AAPG Structural Styles of the Middle East is back! This exciting and highly anticipated Geoscience Technology Workshop will take place from 6 – 8 April 2026, in Muscat, Oman. This workshop aims to explore the diverse structural styles resulting from the different deformation phases on the tectonostratigraphic framework of the Arabian Plate and adjacent regions.
The course will review core data, petrophysical comparisons, rock physics modeling (including pseudo logs and mechanical properties).
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.
This presentation describes a proven workflow that uses a standard narrow azimuth 3D seismic, conventional logs, image logs and core data to build five key reservoir properties required for an optimal development of shale plays.
The goal of this e-symposium is to review an important dimension in the ways geologist can build and update geological models using information from performance data.
This e-symposium will focus on how surface geochemical surveys and Downhole Geochemical Imaging technologies can be utilized jointly to directly characterize the composition of hydrocarbons vertically through the prospect section.
Salt welds form due to salt thinning by mechanical (e.g., salt-flow) and/or chemical (e.g., salt-dissolution) processes. This webinar explores how we use 3-D seismic reflection, borehole, and biostratigraphic data to constrain the thickness and composition of salt welds, and to test the predictions of analytical models for salt welding.
This study will focus in the combination of λρ – μρ inversion with clustering analysis techniques in order to discriminate brittle zones in the Barnett Shale.

This presentation is designed for exploration/production geologists and geological managers or reservoir engineers.
Geologic interpretations are the basis of most exploration workflows, whether building a 3-D framework, a geocellular model, or modeling HC basins and estimating HC reserves. All these workflows rely on the most realistic and accurate interpretation in order to produce high-confidence results. Join us to hear from Catalina Luneburg, founder and director of TerraEx Group and specialist in the validation of HC basins and structural geology modeling.
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.

For well over a century there have been conflicting indications of the strength of the crust and of faults and what controls them. Much of our ignorance comes quite naturally from the general inaccessibility of the crust to measurement--in contrast with our understanding of the atmosphere, which is much more accessible to observation as well as more rapidly changing. Crustal strength is best understood in deforming sedimentary basins where the petroleum industry has made great contributions, particularly in deforming petroleum basins because of the practical need to predict. In this talk we take a broad look at key issues in crustal strength and deformation and what we can learn from boreholes, earthquakes, active fault systems, and toy models.

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.

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.

Subsurface risk and uncertainty are recognized as very important considerations in petroleum geoscience. And even when volume estimates are relatively accurate, the reservoir characteristics that determine well placement and performance can remain highly uncertain. In analyzing results and work practices, three aspects of uncertainty are reviewed here.

Engineering of wind farms, development of carbon sequestration projects in shelfal waters, the proliferation of communication cables that connect the world, all of these things suggest that it is time to re-examine what we know about shelf processes both updip-to-downdip and along shoreline, and the influence of shelf processes on erosion and transport of sediments.

Production from unconventional petroleum reservoirs includes petroleum from shale, coal, tight-sand and oil-sand. These reservoirs contain enormous quantities of oil and natural gas but pose a technology challenge to both geoscientists and engineers to produce economically on a commercial scale. These reservoirs store large volumes and are widely distributed at different stratigraphic levels and basin types, offering long-term potential for energy supply. Most of these reservoirs are low permeability and porosity that need enhancement with hydraulic fracture stimulation to maximize fluid drainage. Production from these reservoirs is increasing with continued advancement in geological characterization techniques and technology for well drilling, logging, and completion with drainage enhancement. Currently, Australia, Argentina, Canada, Egypt, USA, and Venezuela are producing natural gas from low permeability reservoirs: tight-sand, shale, and coal (CBM). Canada, Russia, USA, and Venezuela are producing heavy oil from oilsand. USA is leading the development of techniques for exploring, and technology for exploiting unconventional gas resources, which can help to develop potential gas-bearing shales of Thailand. The main focus is on source-reservoir-seal shale petroleum plays. In these tight rocks petroleum resides in the micro-pores as well as adsorbed on and in the organics. Shale has very low matrix permeability (nano-darcies) and has highly layered formations with differences in vertical and horizontal properties, vertically non-homogeneous and horizontally anisotropic with complicate natural fractures. Understanding the rocks is critical in selecting fluid drainage enhancement mechanisms; rock properties such as where shale is clay or silica rich, clay types and maturation , kerogen type and maturation, permeability, porosity, and saturation. Most of these plays require horizontal development with large numbers of wells that require an understanding of formation structure, setting and reservoir character and its lateral extension. The quality of shale-gas resources depend on thickness of net pay (>100 m), adequate porosity (>2%), high reservoir pressure (ideally overpressure), high thermal maturity (>1.5% Ro), high organic richness (>2% TOC), low in clay (<50%), high in brittle minerals (quartz, carbonates, feldspars), and favourable in-situ stress. During the past decade, unconventional shale and tight-sand gas plays have become an important supply of natural gas in the US, and now in shale oil as well. As a consequence, interest to assess and explore these plays is rapidly spreading worldwide. The high production potential of shale petroleum resources has contributed to a comparably favourable outlook for increased future petroleum supplies globally. Application of 2D and 3D seismic for defining reservoirs and micro seismic for monitoring fracturing, measuring rock properties downhole (borehole imaging) and in laboratory (mineralogy, porosity, permeability), horizontal drilling (downhole GPS), and hydraulic fracture stimulation (cross-linked gel, slick-water, nitrogen or nitrogen foam) is key in improving production from these huge resources with low productivity factors.

The Energy sector is a changing business environment. Throughout the 20th century fluctuations of oil supply and demand produced changes in the barrel price that pushed the growth or shrinkage of the industry. In this 21st century, new challenges such as diversification of the energy mix, boosting gas demand, require the exploration of critical minerals and development of new technologies as well.
