The abstract submitting process has begun for the next AAPG Annual Convention, which will be held April 1-4 in Long Beach, Calif. The theme is “Understanding Earth Systems -- Pursuing the Checkered Flag.”

You ain’t seen nuthin ‘til you’ve seen the Tuscaloosa! Sound familiar? If so, it’s because this was probably the most popular talk making the rounds of the professional meeting circuit in the late 1970s.

Oil in Belize. It could be an epic poem written by Byron, or a knowing verse by Rudyard Kipling. It’s also a ripping adventure, with a small band of True Believers finding victory on a remote frontier.

Geology 101 teaches that the past is the key to the present. This premise, however, depends on accurate interpretation of the past.

If you’ve never had a close-up encounter with a deepwater turbidite, perhaps it’s time. In fact, you may be surprised at the ready accessibility of some really fine outcrops of these type of rocks.

A March announcement that the U.S. Geological Survey had identified undiscovered oil reserves 18 times the amount originally thought in a certain location and three times the amount of natural gas there likely caused many a Pavlovian response. Whetted appetites may have dried a bit with the realization of the potentially lucrative site’s location: northern Afghanistan.

Officials are calling the first-ever AAPG European Region conference to be held in Mallorca, Spain, a “great success.” The conference, “Architecture of Carbonate Systems Through Time,” was held in late April and attracted over 130 attendees from 31 countries -- and over half of those attending were members of AAPG.

Many people today view land surfaces from commercial airplanes or on satellite images and are amazed by the geomorphic forms of river channels, deltas, barrier islands, dune fields and other features. These views show us modern stratal-time surfaces of exposed landforms. Three-D seismic technology has now made it possible to image similar, but much older, geomorphic features and stratal surfaces preserved in the rock record.

As I am writing this column I am returning from the first European Region field workshop held in Mallorca, Spain. Once again, I am wondering how close the airlines are going to move the seats (my knees are now arm rests for the person in front of me), and eating food that nobody would touch in a regular restaurant.

Several new education opportunities have been added to the AAPG calendar -- for both the classroom and beautiful outdoor settings -- and now is the time to add them to your schedule in the next few months.

American Association of Petroleum Geologists (AAPG)
Workshop
Tulsa, Oklahoma
Tuesday, 18 February Wednesday, 19 February 2025, 7:00 a.m.–5:00 p.m.

Join us for AAPG Orphan, Abandoned, Idle and Marginal Wells Conference 2025. This workshop will focus on orphan, abandoned, idle, and marginal wells and the business opportunities and technology associated with plugging and repurposing wells, reducing methane emissions, protecting water supplies, and extending the lives of marginal wells.

Field Seminar
Houston, Texas
Saturday, 1 February 2025, 8:30 a.m.–1:00 p.m.

Everyone in Houston lives within a few miles of a bayou. Some people think of them as permanent, but the bayous are constantly changing, especially during high water events like Hurricane Harvey. This trip is a 2.5 mile walk down a section of Buffalo Bayou where we will look at the archives of past storms and discuss what to do for future storms.

Short Course
Tulsa, Oklahoma
Thursday, 20 February 2025, 7:30 a.m.–4:00 p.m.

This introduction to methane monitoring, measurement, and quantification is for all those who would like to understand the requirements and regulations regarding methane emissions and to be able to design a measurement and monitoring solution, complete with the appropriate types of technologies, techniques, and safety protocols.

VG Abstract

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.

DL Abstract

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.

DL Abstract

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.
