Challenges to Deepwater Reservoir Characterization

It is no secret that deepwater depositional systems hold some of the largest petroleum reservoirs on Earth. To get those reserves out safely, effectively and economically from such depths requires technology, expertise, and a little bit of luck. The challenges associated with doing that – determining the presence, distribution and quality of those reserves – is the work of the Quantitative Clastics Laboratory at the Bureau of Economic Geology at the University of Texas at Austin.

Pacific Section Conference Soars with Virtual Field Trip to the Monterey Formation

AAPG Pacific Section thrilled attendees with a stunning interactive Google Earth-based virtual field trip. Imagine being able to experience the stunning and intricate layered geology of the Monterey Formation through a Google Earth high-resolution, interactive program. Richard Behl, geology professor at California State University at Long Beach, likes to take geologists into the field, walking through the cool surf and sunny climate. At the Pacific Section virtual conference in late June, Behl offered up what he described as a “Monterey Formation Bucket List” of beach outcrop stops traversing more than 500 miles along the California coast from Crystal Cove and up to Bowling Ball Beach near Point Arena. That was only the start of the multiday technical program that was both innovative and technically enriching.

Virtual Field Trips Yield Real Life Results

Last summer, nearly 30 geoscientists and engineers from the Canadian Society for Unconventional Resources trekked through an array of outcrops in the Sulphur Mountain Formation to piece together how the Montney Formation – Western Canada’s most prolific resource play – was formed. Rock by rock, they saw how the outcrops revealed a history of sedimental deposition, sedimentary structures, trace and body fossils, and even a bone bed. And, rather than getting there by airplane or car and hiking over tumultuous terrain, they navigated each nook and cranny from the comfort of their homes. For most CSUR members, it was their first virtual fieldtrip and will likely not be their last.

Oil and Gas Fields of the 22nd Century: The Quest for Economic and Environmental Sustainability on Continental Margins

Economic oil and gas fields have been increasingly found in deep-water continental margins for the past decade, where potential prospects record the key tectonic events associated with plate breakup and continental drift. In these regions, the exploitation of economic resources must take into account sustainable practices and environmental concerns of local populations. This talk will present case studies from multiple continental margins to then extrapolate major findings to basins in SE Asia.

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.

The Shelf is a Dangerous Place: Surfing the Cretaceous Seaways

Engineering of wind farms, development of carbon sequestration projects in shelfal waters, the proliferation of communication cables that connect the world, all of these things suggest that it is time to re-examine what we know about shelf processes both updip-to-downdip and along shoreline, and the influence of shelf processes on erosion and transport of sediments.

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.
