A Retrospective on Source Rocks as Reservoir Rocks

In a recent EXPLORER, Marlan Downey lamented that he had not fully appreciated the idea that source rocks could serve as reservoir rocks for oil and natural gas. He was not alone.

All Eyes Are on Unconventionals

As U.S. production continues to grow, all eyes are focused on OPEC and its recent May 25 meeting to determine whether to keep production cuts in place in an effort to maintain oil prices.

Extending the Reach of Drones: Interview with Jim Cieplak, Harris Corporation

Drones are currently being used in many applications, including pipeline and tank inspections, as well as methane leaks and seeps. Money is being saved. Resources are being discovered. But, behind the use of most drones and UAVs is the issue of safely and legally operating beyond the visual line of sight (BVLOS). Welcome to an interview with Jim Cieplak, who talks to us today about his work with Harris Corporation and BVLOS solutions.

Raymond's Folly: The Codell Play of the Denver Basin

The present day Cretaceous Codell oil and gas development in the central portion of the Denver Basin of Colorado can be attributed to an earlier effort in bringing the Codell to the attention of the industry.

Muscat, Oman

Monday, 6 April – Wednesday, 8 April 2026, 8:00 a.m.–5:00 p.m.

3rd Edition: Structural Styles of the Middle East

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.

Tectonic Controls on Source Rock Deposition

While there are many habitats that are associated with the deposition of organic-rich marine and lacustrine source rocks, one important pathway is linked to the onset of increased basin subsidence associated with major tectonic events. A key aspect is that this subsidence is spatially variable, with the uplift of basin flanks contemporaneous with the foundering of the basin center, resulting in a steeper basin profile.

Subsurface Machine Learning Approaches at Hydrocarbon Recovery and Resource Forecasting for Unconventional Reservoir Systems

This presentation is a survey of subsurface machine learning concepts that have been formulated for unconventional asset development, described in the literature, and subsequently patented. Operators that utilize similar subsurface machine learning workflows and other data modelling techniques enjoy a competitive advantage at optimizing the development of unconventional plays.

Interactions Between Ice Sheets and Relative Sea Levels: Lessons From Antarctica and NW Scotland

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.

How Orogens Could Collapse Forming Sedimentary Basins: The Case of the Betic-Rif Orogen

The Betic hinterland, in the westernmost Mediterranean, constitutes a unique example of a stack of metamorphic units. Using a three-dimensional model for the crustal structure of the Betics-Rif area this talk will address the role of crustal flow simultaneously to upper-crustal low-angle faulting in the origin and evolution of the topography.

Estimating, Benchmarking, and Managing Subsurface Uncertainty: Principles and Examples

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.

VG Abstract By Juan I. Soto

Salt versus Shales in Continental Margins and Orogens

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.

Shaping New Leadership in an Evolving Energy Business

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.

Reconstructing a Late Pleistocene East African Paleolandscape using the Footprints of our Ancestors

Fossil hominin footprints offer a unique and immediate snapshot of our ancestors' lives, capturing their ecological, environmental, and behavioral contexts over remarkably short time scales. This presentation delves into the discovery and analysis of over 400 human footprints from Engare Sero, Tanzania, located on the southern shore of Lake Natron.
