The call for abstracts deadline is Jan. 15 for the next AAPG International Conference and Exhibition – a meeting that will be historic on many levels. This year’s ICE will be held Sept. 13-16 in Melbourne, Australia – the first time AAPG has used that city as a setting for ICE.

In international exploration, the new normal is starting to look like the old normal. And 2014 looked a lot like the year before.

There’s a major scientific initiative evolving in Baton Rouge, La., that is expected to have a positive impact around the globe. It’s the relatively new Water Institute of the Gulf, appropriately located in this city bounded on its western edge by the majestic Mississippi River as it wends its way southward to meet the Gulf of Mexico.

The call for abstracts is open for the next AAPG International Conference and Exhibition – a meeting that will be historic on many levels. The 2015 ICE will be held Sept. 13-16 in the beautiful city of Melbourne, Australia– the first time ever AAPG has used that city as a setting for ICE. The meeting will be hosted by the Petroleum Exploration Society of Australia.

Like numerous other geologic formations, the allure of the Wilcox has waxed and waned owing to fluctuating commodity prices, among other issues. As hydrocarbon prices recovered and technology applications like hydraulic fracturing became commonplace, the Wilcox beckoned anew, attracting principally the mom-and-pop shops and the small to mid-size independents.

Designed to expose geoscientists to the language and methodologies commonly employed by reservoir engineers to estimate oil and gas reserves, this course will include a brief review of reservoir rock properties, introduction to fluid properties, reservoir drive mechanisms, and commonly used techniques for estimating reserves including analogy, volumetric analysis, material balance, decline curve analysis, and computer simulation.

Explorer Historical Highlights

The relatively recent, very large discoveries offshore Brazil have put pre-salt exploration in the South Atlantic back in the foreground. Pre-salt exploration history, however, is far more ancient and marked with some major successes – but also many failures. Here’s a brief overview of this exploration in West Africa until the M’Boundi discovery, which will be described in detail as it brings some lessons that readers can discover for themselves.

In the age of 3-D seismic and digitized well logs, the value of cores and other rock samples may not be obvious. But benefits like those noted by the AAPG in 1948 and described in a 2002 National Research Council report and a recent congressional hearing continue to demonstrate the value of properly archived subsurface samples and data.

Three speakers from the AAPG-AAPG Foundation’s Global Distinguished Lecture Program will be on tour in November, making stops in the western parts of North America and throughout the Asia-Pacific Region.

Short Course
Tunis, Tunisia
Monday, 12 September 2022, 8:00 a.m.–4:30 p.m.

This short course will comprise lectures, short exercises and discussion sessions. The course will focus on a number of case studies that link outcrop and subsurface geology and have relevance to petroleum exploration and production. Case studies range from Silurian to Miocene in age and come from North African and Mediterranean Basins. The course builds on basic knowledge of sedimentary geology but does not require specialist skills from participants.

Workshop
Lisbon, Portugal
Thursday, 18 May Friday, 19 May 2023, 8:00 a.m.–5:00 p.m.

This 2-day conference brings together diverse experts working on modern and ancient turbidite, MTDs, contourite and hybrid/mixed systems in order to improve the present-day knowledge, models and predictive power.

VG Abstract

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.

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.

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.

VG Abstract

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.
