Explorer Director’s Corner

Traveling to the Middle East is something that I get a lot of questions about, particularly from colleagues and friends in the United States and Europe who have never done so. Based on the headlines they read, they’re surprised to hear me say that it is one of my favorite places to travel. The people of the Kingdom of Saudi Arabia warmly welcomed IPTC attendees, and a spirit of hospitality pervades cultures in the Middle East. You need to experience it. And next month we, AAPG, together with EAGE and SEG, will enable you to do just that as we launch GEO 2020, the 14th Middle East Geosciences Conference and Exhibition in Bahrain, with the theme “Geosciences in the Digital World: 2020 and Beyond.”

Necessity may be the mother of invention. But sometimes it’s just all the mosquitos. Leila Donn, a doctoral student at the University of Texas at Austin studying environmental geoscience, wasn’t necessarily looking for a computer model to help her find the location of ancient Mayan caves last year. Mostly, she just was hot and tired and the work was going slowly.

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.

Explorer Historical Highlights

The Chixchulub crater on Mexico’s Yucatan Peninsula was long believed to be the result of volcanic activity, until one young geologist with a No. 2 pencil, some drafting triangles and a calculator made an earth-shattering discovery.

When new technology enters the oil and gas scene, talk of layoffs can creep into water-cooler conversations. Will better software and computers replace people, or will they push the industry forward, creating the need for additional staff? These questions are especially pertinent for geophysicists today, as artificial intelligence and machine learning technologies are processing and interpreting seismic data at record speeds, often delivering results that rival, if not surpass, that of humans. With some software companies calling their platforms a “seismic revolution” by offering real-time data interpretation, geophysicists might question how they will fit into this new, seemingly supersonic world.

The Upper Jurassic (Oxfordian) Smackover Formation is one of the most prolific oil and gas producers in the northeastern Gulf of Mexico coastal plain, where it deposited in a proximal carbonate ramp. This study is a comprehensive characterization of the depositional environment of the Smackover based on 3D seismic and well data from wells in the Vocation and Appleton oil fields located in the Conecuh and Manila Sub-basins in southwest Alabama.

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

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.
