New Institute Eyes Global Water Management

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.

Abstracts Sought for Melbourne ICE

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.

Wilcox Trend Sees Renewal

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.

Mexico: Opportunities Require Geology

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.

West Africa Offers Lessons in Pre-Salt Exploration

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.

A Case for Reauthorizing the Data Preservation Act

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.

Mississippi Lime: Good Things On The Horizon

At first glance it seems there’s not much overtly new about drilling in the Mississippi Lime – or overtly new about the Mississippi Lime play, either, for that matter – a play that oozes from northern Oklahoma through southern Kansas (and some say, perhaps, to Nebraska).

Connecting Researchers With Funding

AAPG is committed to connecting promising original research with much-needed funding and is continually seeking – and finding – new ways to make that potential a reality.

Analyzing Big Data For Big Discovery

Unconventional plays are producing hundreds of wells within relatively small spaces, and all are cranking out more data than any human could possibly track. It’s a fact that has driven the oil and gas industry to search for technology that can intelligently quantify such data and increase the odds of a discovery.

VG Abstract By Keith Gerdes

Tethyan Carbonates - Linking Tropical Seas and Crashing Plates to Some of the Largest Oil and Gas Fields in the World

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 By Tao Sun

Integrated Reservoir Characterization and Modeling with Computational Stratigraphy

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.
