“The beauty of the unconventionals is, while they’re expensive, we know where they are.” That’s Carlos Torres-Verdin, Brian James Jennings memorial endowed chair and Zarrow centennial professor of petroleum engineering at the University of Texas at Austin, talking about the promise of unconventional energy production in the United States, both from an industry standpoint and with a view to its position in the country’s future energy mix. According to a study by the Harvard University Business School, by 2030, 3.8 million jobs, half of which would be accessible to middle-skilled workers, could potentially be supported by the development of unconventional resources.
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.
Unconventional resource development has a remarkable history, combining breakthroughs and advances in both technology and geoscience. The pace of progress might have slowed in recent years, but that history is still being written.
The goal of reservoir characterization work carried out for a shale play is to enhance hydrocarbon production by identifying the favorable drilling targets. The drilling operators have the perception that in organic-rich shale formations, horizontal wells can be drilled anywhere, in any direction, and hydraulic fracturing at regular intervals along the length of the laterals can then lead to better production. Given that this understanding holds true, all fracturing stages are expected to contribute impartially to the production. However, studies have shown that only 50 percent of the fracturing stages contribute to overall production. This suggests that repetitive drilling of wells and their completions without attention to their placement must be avoided, and smart drilling needs to be followed by operators.
'Sourced in part by the Eagle Ford Group, the Austin Chalk has been a hot spot for operators on and off for a century. The rise of horizontal drilling and hydraulic fracturing brought a renewed interest in the formation, which has produced new discoveries in Texas and Louisiana. Yet in parts of the Austin Chalk, extracting oil and gas can be extremely tricky. Several years ago, the Carbonate Reservoir Characterization Research Laboratory at the University of Texas began a project to analyze approximately 40 cores from the Austin Chalk – the first group to do so.
Exploration of the Brookian-age Nanushuk and Torok formations on the North Slope of Alaska is a hot topic these days. The Nanushuk and Torok formations are Cretaceous progradational clastic deposits in the Colville basin of Alaska. These formations offer new opportunities to the oil and gas community because of their shallow depth, vast spatial extent, publicly available data, scope of development and other appealing features.
Geologists will soon have a set of software tools that can automatically correlate hundreds of stratigraphic tops that will encompass thousands of well logs. The new approach – a software Python package, ChronoLog – will potentially change how such compilations are done.
Some 257 people gathered at the beautiful new Hilton Hotel in Port Moresby, Papua New Guinea in the last week of February 2020 to attend the first AAPG/EAGE Papua New Guinea Petroleum Geoscience Conference and Exhibition. The theme for the conference was, “PNG’s Oil and Gas Industry Maturing Through Exploration Development and Production.”
In 1994, while chairman and CEO of Barrett Resources, I got a call from my good friend Ray Thomasson, who said, “Bill I have a prospect Larry McPeek has worked up in the Wind River Basin that you might find interesting.” I’d worked every feature of geology in Wyoming’s Wind River Basin and was familiar with about every well drilled there during my career, so I frankly considered myself somewhat of an expert on the basin ... The Cave Gulch Prospect was located along the Owl Creek Thrust in a geologically complex area.
AAPG functions because of you, the members, and there are many different ways for you to get involved in your organization. Some choose to start in their local affiliated society, working on committees and holding offices within them. Others get involved through leadership and organizing events within the sections and regions. These are the grassroots of our membership, and AAPG leadership is working to strengthen these roots.

This field trip will take you from Salzburg to the UNESCO World Heritage Site of Hallstatt, where salt has been exploited for 5000 years and where we will take a look at the interaction of salt diapirism with syn-tectonic sedimentation. The impact of the Hallstatt diapir on our understanding Alpine orogenesis will be discussed. You will also be given a brief overview of the spectacular Bronze Age mine galleries of Hallstatt!
This is an interactive field trip! You will guide yourself to the outcrops from the comfort of your desk. Anybody wishing to participate in this pre-conference field trip (Oct. 18th) needs to have access to a computer with GoogleEarth installed.
KMZ files (total size of hundreds of MB) will be distributed prior to the field trip via download link to all participants. It will be the participants' responsibility to show up to the field trip with these files downloaded and open in GoogleEarth. During the field trip, we will access the internet to visualize 3D models in Sketchfab; a suitable browser and good connection speed are also required. Please test beforehand on any Sketchfab model.
This course aims to help teams characterize and interpret deep-water stratigraphy and reservoirs. The course described here will help corporate teams mature exploration concepts in areas of interest, as well as aid in the development decisions of existing fields.
This two-day virtual conference aims to bring together industrial and academic persons to present, explore and develop approaches that will benefit both sectors in the future. The virtual conference will focus on current techniques, the challenges and future solutions in understanding the Triassic stratigraphy of the North Sea, Norwegian Sea, West of Shetland, Atlantic margins, and northern Europe.
This course is informed by over 20 years working in oil and gas exploration and production with many companies and clients and by a further 15 years teaching structural and petroleum geology at Universities in Australia.
This two-day trip will examine classic exposures of the Middle to Upper Cretaceous (Cenomanian to Campanian) strata of the southern Denver Basin near Pueblo, Colorado. Although the focus is on exceptional mudrock and tight sandstone outcrops of the Graneros, Greenhorn, Carlile, and Niobrara formations, currently of great interest for oil and gas exploration, lessons learned are directly applicable to other unconventional systems.
Natural fractures may be conductive in conventional reservoirs or may become conductive after hydraulic stimulation in unconventional reservoirs. This course addresses these concepts by examining datasets from both conventional and unconventional systems and presenting workflows to construct naturally-fractured reservoir models.
Energy Storage and CCSU are emerging fields that are already new business opportunity for petroleum professionals. This workshop reviews the basics of different Energy Storage Technologies, CCSU, and injection induced seismicity.
As we transition to a new commercial reality for our industries, there has never been a more important time for Earth Scientists to take a seat at the table. This workshop is designed to share our knowledge of the petroleum sector with other branches of the geosciences, while learning from their experiences.
Join us for this hybrid online and in-person workshop on 6 July 2022.
Politicians around the world are realising that CCS is a critical component in achieving Net Zero. They know in principle what needs to be done but lack insight into which of their many assets is a natural choice for CCS and how to convince stakeholders to commit to financial investment. If it was a horse race, they need to choose the best runners and know how to jump the hurdles to get to the finishing line.
In this second AAPG CCS workshop, we'll look deeper into the technologies available and the techniques to make them affordable. The 'Runners' and how to 'get them to the finish line.
Modelling carbonate sequences and reservoirs has always been a challenging task. Carbonate rocks are generated and subsequently modified by a large variety of biological, physical and chemical processes that start at the time of deposition and end today. To unravel the geological evolution and history of carbonate sequences is fundamental not only for understanding their hydrocarbons potential but also for their role as potential reservoirs for renewable energy (geothermal) or geological gas storage (CO2 and hydrogen).
Several science disciplines are often involved to fully understand the characteristics of carbonate rocks and old approaches and new technologies and tools are nowadays applied in these types of sequences.
The objective of this meeting is to allow scientists and engineers working on carbonate rocks in academia and industry to share their most recent experience, work, approaches and use of innovative technologies to increase the understanding of the very complex world of carbonates.
Save the date! Join us for the Exploration in Mature Basins GTW to be held from 7-9 February 2022 in Muscat, Oman. More information to follow soon.
Stratigraphy remains an essential part of geoscience practices. It provides our conceptual framework for visualizing how layers are arranged and connected in the subsurface. The workshop aims to share, discuss and explore many of the new ideas regarding the stratigraphy of the hydrocarbon-bearing basins throughout Sundaland.

The aim of this 2-day field trip is the recognition of the key structural features of a fold and thrust belt detached on salt that has resulted from the inversion of a previous passive margin. To achieve this objective, some of the key and most spectacular localities of the southern Pyrenees have been selected along the ECORS-Pyrenees transect. This is a reference cross-section provided that for many years a huge amount of geological and geophysical data sets has been collected and integrating into a kinematic model of the South-Pyrenean fold and thrust belt. Subsurface data (well logs and seismic sections) will be combined with field observations. One of the main characteristics of the southern Pyrenees is the preservation of the synorogenic sediments since the earlier stages of deformation, which not only provide time constraints but also allow us discussion of kinematics of fault-related folds and thrust systems. Finally, the mild contractional deformation permits deciphering the initial geometry of the rift system and the salt structures that configure the structural grain of the passive margin before the inversion, allowing discussion of the role that these structures play during the fold and thrust belt development.
Itinerary: (day by day details of the trip)
Stop 1.1: The South-Pyrenean thrust front. Sant Llorenç de Montgai
Structure of a frontal thrust system and related unconformities. Out of sequence thrusts and synorogenic sediments.
The frontal thrust system of the South-central Pyrenees has been detached into the Triassic evaporites and involves a thin Mesozoic succession. It is characterized by an emergent thrust system during the sedimentation of upper Eocene and lower Oligocene continental sediments. Frontal thrusts were progressively buried by conglomerates, triggering a break-back thrusting sequence and the development of out-of-sequence thrusts bringing together strongly different Mesozoic successions, such as the Montroig thrust in the picture.
Stop 1.2: The Ager basin and the Montsec thrust sheet. Fontllonga
The Ager basin in the footwall of the Montsec thrust.
The Montsec thrust sheet developed from the Paleocene to the Early Eocene as recorded by continental to shallow marine sediments deposited in its footwall (Ager basin) as well as in the Tremp-Graus piggy-back basin. The lower Eocene sediments of these basins grade westward into the slope succession filling the Ainsa basin at the footwall of the Montsec thrust.
Stop 1.3: The frontal structure of the Montsec thrust sheet. Ametlla (optional: Montrebei)
Fault-propagation fold related with the inversion of Early Cretaceous extensional faults and growth deltaic sediments in the footwall syncline.
The Montsec thrust sheet involves the northern part of the Upper Cretaceous foreland basin characterised by a strong subsident turbiditic trough at the footwall of the Bóixols thrust. These turbidites grade southward into a carbonatic platform that constitutes the backbone of the Montsec Range (main ridge and cliff of the pictures). Underneath the Upper Cretaceous carbonates, some Early Cretaceous extensional faults are preserved in the hanging wall of the Montsec thrust, but others have controlled the development of a hanging wall frontal anticline. The geometry of this anticline as well as the structure of the growth sediments in the footwall Ager syncline are visible in the field. The subthrust geometry will be discussed integrating surface observations and the available seismic and well data.
Overnight in Tremp
Stop 2.1: The Sant Corneli-Bóixols anticline
Inversion of the rift margin
The Sant Corneli-Bóixols anticline is the most prominent frontal structure of the Bóixols thrust sheet in the central Pyrenees. This fold trends east–west and crops out for greater than 40 km along strike. The Sant Corneli-Bóixols anticline involves a thick Mesozoic succession detached on top of Triassic evaporites. The prefolding sequence consists of up to 5 km of prerift, synrift, and postrift carbonates ranging in age from Jurassic to Upper Cretaceous. Synfolding Upper Cretaceous sediments start with the upper Santonian carbonates and continue with a succession of Campanian and Maastrichtian marls and turbidites.
The Sant Corneli–Bóixols anticline is an example of an inversion fold developed along the rift margin of the Lower Cretaceous basin. Its geometry is related with the inverted extensional system. In particular, the three-dimensional geometry, including the saddles between culminations, is inherited from the previous transfer faults of the segmented rift margin.
Available seismic data and 3 exploratory wells constrain the geometry at depth.
Stop 2.2: The synororgenic Paleogene conglomerates
Inverted Lower Cretaceous basin and Eocene-Oligocene synorogenic conglomerates at Collegats gorge.
Stop 2.3 (optional): The Sopeira and Aulet minibasins. Sopeira
Minibasins developed by extensional collapse and salt evacuation during the thermal subsidence at the southern Pyrenean rift margin. Inversion of these mini-basins at the early stages of Pyrenean contractional deformation during Late Cretaceous.
Additional logistic information
Transportation will be with a small bus, assisted by minivans to have access to some of the outcrops.
Physical demand, equipment and safety
This is an easy field trip with very easy and limited hikes to get to the outcrops. Outcrops will be from main sealed roads.
Safety vests will be available, to be used by everybody of the group wherever required and asked to. There will be First Aid Kits available in each car during fieldwork.
The climate during mid-end November in the fieldwork area can be cold and rainy, although dry and sunny days may occur as well. The temperature for November in Tremp can range between 30C and 170C. Participants should be prepared in case we should encounter bad weather and you should bring warm and waterproof clothes and suitable hiking boots. -->

To gain or increase an understanding of the tectono-sedimentary processes of continental extension and rifting supported by outcrop observations, with focus on deep-depositional marine systems. Discuss implications for prospective petroleum systems. Promote debate and nourish new insights between attendants.
About the Field Trip
The Lusitanian Basin records the proximal events of syn- to post rift evolution of the hyper-extended West Iberian Margin, showing some outstanding examples of the combined tectono-stratigraphic depositional systems. Here, the Late Jurassic reveals diverse aspects of mixed marine depositional systems including not only submarine fans and turbidites, but also the build-up of carbonate reefs and shoreface to fluvial clastic sequences. Throughout the fieldtrip the different depositional aspects can be observed in detail to demonstrate how such depositional systems can vary in time and space. Observation of these outcrops allows a better understanding on how deep-water depositional systems can change within a sub-basin and help improving the understanding of reservoir properties.

This workshop brings together experts from academia and industry from a range of disciplines to share experiences, new approaches, new data and new ways of integrating information that can help in reducing the uncertainties related to the exploration activities in Thrust Belt Systems.
The workshop aims to provide a comprehensive understanding of the source rocks in the Middle East. The technical program is developed in a way that coves the depositional environments and transport processes, basin modeling and detailed rock characterisation including geochemisty, geomechanics and petrophysics.
Join us virtually in this event that was due to be hosted in Salzburg, the “castle of salt” and cradle of Mozart and Doppler.
We aim to host an interactive meeting aimed at bringing together different perspectives in the science of evaporite basins: from their formation to their deformation, from description and characterization to modelling. Exploratory success in evaporite-rich basins worldwide has depended on the role of evaporites as a deformable substrate, as a seal, or even as a good thermal conductor. The aim of this workshop is to improve our understanding and predictive ability by addressing evaporite systems in an integrated manner, all the way from precipitation to structuration, and exploring the multiple properties of evaporite sequences. This will be done via technical sessions, keynote speaker presentations, panel sessions and more!

Water cut is a big factor in gauging the success of horizontal drilling in the Mississippi Lime Play (MLP). The contributing factors are related in part to the spectrum of producing lithofacies and reservoir quality encountered that varies laterally and vertically, sometimes dramatically.
This work investigates how heterogeneity can be defined and how we can quantify this term by describing a range of statistical heterogeneity (e.g. coefficient of variation and the Lorenz coefficient).
This e-symposium will be introducing signal processing techniques as a means to maximize extracting geomechanical data from petrophysical logs.

This lecture will discuss the differences between carbonates and siliciclastics from their chemical composition through their distributions in time and space. Building on these fundamental differences, we will explore the challenges carbonates pose to petroleum geologists in terms of seismic interpretation, reservoir quality prediction, field development, etc. Peppered with humorous personal stories, still raging academic debates, and the heartfelt frustrations of real industry professionals, the aim is to inspire students and young professionals to rise to the occasion and embrace the reservoir rocks that petroleum geologists love to hate.

Microseismicity induced by hydraulic fracture stimulation of a horizontal well was mapped with a near-surface buried array. Distinct linear trends of events were not parallel to the direction of fast shear wave polarization measured in the reservoir with a crossed-dipole anisotropy tool. Analysis of core from a nearby well revealed numerous calcite-filled fractures that did not induce shear wave polarization, but did significantly impact the failure behavior of the reservoir rock during the stimulation treatment. Hydraulic fracture simulation with DFN modeling and source mechanism analysis supports the interpretation of reactivated existing fractures rather than the formation of hydraulically-induced tensile fractures.

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.

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.
