Remembering Emma Giddens

Emma Giddens was a California girl who fell in love with carbonate rocks, excelled in nearly everything she tried, led her IBA team to a Selley Cup victory and even as a graduate student was known internationally for her “pioneering” research. In fact, professors at three schools marveled at her passion for geology, her intelligence, her kindness and mentorship of fellow students. Tragically, Giddens died shortly after receiving word that her research was being honored with an AAPG Foundation Grant-in-Aid.

Mars Resources for Human Settlement

On July 30, NASA’s Jet Propulsion Laboratory launched the Mars 2020 Perseverance rover. Perseverance is destined to land at Jezero crater on Feb. 18, 2021, with the most sophisticated kit of geology tools ever assembled for an astrogeology mission. AAPG, as an institution dedicated to exploring for resource commodities, looks to our future in space through the Astrogeology Committee and the Energy Minerals Division. We emphasize the use of geosciences in the development of off-world exploration energy and other natural resources for development in the foreseeable future. Water resources in space, on the moon and on Mars, will become the energy commodity analog of oil on Earth.

Explorer President’s Column By Rick Fritz

Always Pay Attention to the Really Big Things

If you remember from my last column, this is a three-part series on my thoughts on science, membership and budget. I talked about budget last time … we are still working on it, so let’s talk science. The reason most professionals join AAPG is for access to science. That’s not just my opinion – it’s what members tell us. AAPG is very good about disseminating the work of our members and other professionals around the world. That’s our mission.

Annual G-Camp Goes Virtual

After 13 years of taking teachers into the field, this year’s G-Camp was held virtually in response to the COVID-19 pandemic, organizers said. The program is aimed at 5th through 12th-grade teachers and offers supplemental material for the teachers’ science curriculum. The goal is to have teachers return to the classroom with new knowledge and excited about what they are teaching, and ultimately for “the kids to come to college saying, ‘I want to enroll in geology.’”

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.

The Bight Basin, South Australia, One of the World's Largest Unexplored Deltas. Evolution and Prospectivity; Seismic, Structure, and Balanced Sections

Presented by Kevin C. Hill, Associate Professor, University of Melbourne Gravity modelling of Australia's southern margin reveals that the initial rift with Antarctica was beneath the current Ceduna Delta. A regional, high-quality seismic traverse from the coast to oceanic crust across the Bight Basin has been assembled and interpreted in detail, then balanced, restored, decompacted, and replaced at paleo-water depths. The Late Cretaceous Ceduna Delta developed above a Late Jurassic-Early Cretaceous rift basin in three stages punctuated by significant pulses of uplift and erosion across areas >100 km wide and with up to 1 km of erosion. The Cenomanian White Pointer delta prograded into deepening water and hence underwent gravitational collapse. This was terminated in the Santonian when the Antarctic margin was pulled out from below, thus supplying heat to a remnant thicker outer margin crust, causing doming and erosion. Importantly, this established the saucer-shaped geometry of the Ceduna Delta that persisted throughout its development, so that any hydrocarbons generated in the southern half of the basin would have migrated towards this outer margin high. The Tiger Formation was deposited in shallow water in a full rift basin prior to breakup, which was followed by regional thermal subsidence. The Hammerhead delta developed on the newly formed passive margin but was terminated by another pulse of uplift and erosion, perhaps associated with a change in plate motion at the end of the Cretaceous. The finite element modelling of this proposed tectonic evolution will test its validity and predict hydrocarbon generation and migration through time.

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.

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.
