I am pleased to serve as president of the Energy Minerals Division for 2018-19. My main goals for this year are to provide frequent, easily accessible, relevant, high-quality technical content, and to improve our member engagement and communication with the regions, local societies and other geological associations.

Exploration and development drilling along the upper region of the Middle Pennsylvanian Red Fork Sandstone has been going on since 1979 in the western part of the Anadarko basin of Oklahoma. Fangyu Li, a postdoctoral research associate in the College of Engineering at the University of Georgia, said the latest technology in multispectral coherence is developing to a point where scientists can see more of what’s down there and they can see it more clearly.

“Big data” and “data analytics” are the buzzwords these days. In the last decade, our industry grappled not only with ever-larger volumes of data, but also with increased data heterogeneity. Recent developments in data analytic capabilities applied to other industries hold significant promise for those of working in the hydrocarbon exploration and development.

Geoscience education is turning out to be a good fit for the modern university, and an especially good way to position students for the future. In part that’s because of the nature of earth science studies, said Stephan Graham, dean of the geoscience school at Stanford University.

CERA was a diverse and dynamic week. A record-breaking 4,500 CEO’s, leaders, energy ministers and global representatives from more than 70 countries attended the March 4-9 event to ponder the future of the industry. And this year, AAPG got to play an important role in this conversation.

This, the first Annual Convention of AAPG’s second century, is officially designated “ACE 101: Bridging Fundamentals and Innovation.” Vanden Berg explained that the May 20-23 meeting will “provide an opportunity to return to the rocks and to remember the importance of fundamental geologic concepts, but also to look to the future, to harness and embrace new technology and innovation.”

The second edition of the AAPG 'Carbonate Reservoirs of the Middle East & Their Future Challenges” GTW took place on 30 January – 1 February 2018 at the Crowne Plaza Yas Island Hotel, Abu Dhabi, United Arab Emirates. We received 155 attendees from 32 different companies and 14 different countries. This two-day workshop consisted of technical presentations, core display and poster presentations, followed by a third day offering two optional field trips.

With ICE in one of the most iconic European capitals, the organization committee wanted to shape an ambitious field trip program that would look beyond the British Isles. Against all odds dictated by the unfavorable state of the industry, three field trips accompanied from start to end the success of ICE in London.

“Wait! There is a short cut. Turn right from here”. That’s probably the sound of an electric current bypassing the resistive hydrocarbons, in a maze or network of porous media, when traveling from transmitter to receiver. This workshop will serve the participants need with the up to date advancements in describing and characterizing low resistivity and low contrast pay, and eventually, maximize resources.

Tuesday, 20 June 2023, 8:00 a.m.–5:00 p.m.

Come along on this 1-day field seminar and tour outcrops in the Serra de Montejunto, just north of Lisbon and on the coast from Porto Novo to Paimogo. Instructors: Ricardo Pereira, GeoBioTec - Faculdade de Ciências e Tecnologia, Universidade Nova de Lisboa. Gil Machado, ChronSurveys Lda & Instituto Dom Luiz Fees: €190 - Local VAT applicable Limit: 20 Participants Includes: Ground Transportation Snacks and Refreshments Lunch and Dinner Guidebook Departure Time/Location 20 June 2023 8:30am Hotel Dom Pedro Note:Transportation to start point is not included in the costs of this trip. Please bring clothing for hot day time temperatures (sun hat/ sun glasses/ sun cream etc.). Participants must wear suitable and comfortable light trekking shoes. Aims To gain or increase an understanding of the tectono-sedimentary processes of continental extension and rifting supported by outcrop observations, with focus on deep-depositional marine systems. Discuss implications for prospective petroleum systems. Promote debate and nourish new insights between attendants. About the Field Trip The Lusitanian Basin records the proximal events of syn- to post rift evolution of the hyper-extended West Iberian Margin, showing some outstanding examples of the combined tectono-stratigraphic depositional systems. Here, the Late Jurassic reveals diverse aspects of mixed marine depositional systems including not only submarine fans and turbidites, but also the build-up of carbonate reefs and shoreface to fluvial clastic sequences. Throughout the field trip the different depositional aspects can be observed in detail to demonstrate how such depositional systems can vary in time and space. Observation of these outcrops allows a better understanding on how deep-water depositional systems can change within a sub-basin and help improving the understanding of reservoir properties.

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.
