Field Seminar
Palermo, Italy
Thursday, 25 April 2024, 8:00 a.m.–9:00 a.m.

This one-day field trip will provide an introduction to a Miocene-Pliocene succession of southern Sicily, which includes outcrops of the Messinian Salinity Crisis (MSC), as well as the Messinian-Zanclean GSSP (Global Boundary Stratotype Sections and Point) and Zanclean stratotype. The MSC sedimentary record consists of an evaporitic-carbonate unit at the base (the Basal Limestone), overlain the Lower Gypsum unit, in turn overlain by the Upper Gypsum unit, and sealed by transgressive chalk deposits of the Trubi Fm. The Lower Gypsum unit (massive gypsum with cm-sized selenite crystals) will be visited along the beach of Siculiana Marina (about 15 km NW of Agrigento). Next, we will visit near Capo Rossello (about 10 km NW of Agrigento) an outcrop of the Upper Gypsum unit consisting of clay-gypsum cycles and overlain by the Trubi Fm. The latter, at Scala dei Turchi beach, consists of chalk deposits arranged in a spectacular thick succession (~120 m thick) interpreted as astronomically-controlled depositional cycles. The uppermost interval of the MSC sedimentary record, including the Messinian-Zanclean GSSP, will be observed along the beach of Eraclea Minoa located about 20 km NW of Capo Rossello.

Saturday, 11 May 2024, 8:00 a.m.–3:00 p.m.

Time: 8:00am - 5:00pm Fee: $300 AAPG members $350 Nonmembers $200 Academic/AAPG Emeritus Members $50 discount for workshop registrants Fee Includes: Transportation Insurance Field guide Entrance fee to Banff National Park Registration available during workshop registration This field trip will focus on the structural geology of the foothills and Front Ranges of Banff. Participants will be able to view excellent field examples of structures very similar to the producing oil and gas fields in the foothills to the west of Calgary and to learn about the complexities of sub-seismic-scale deformation. The field trip starts with an introduction to the interaction between thrust front with foreland basins and the interaction of basement trends with thrust belt geometries and (conventional) hydrocarbon fields. During the 1-day trip participants will follow a dip transect from the undeformed foreland basin, the eastern edge of the foothills marked by the triangle zone, the Front Ranges boundary and end at the Main Ranges west of Banff. Field Trip Itinerary Depart from Calgary – 8:00 a.m. Stop 1: Cochrane Retreat Road Overlook Trip overview and introduction; safety and logistics comments; interaction of thrust front with foreland basin; interaction of basement trends with thrust belt geometry and (conventional) hydrocarbon field distribution; appreciation of scale for subsurface play fairway. Stop 2: Scott Lake Stop 3: The Stony Nakoda Tim’s Classic stop, with historical importance for understanding the thrust belt and thrust geometry. Part 1 of displacement gradient on a large thrust. Most importantly, toilet stop after all the Tim’s coffee and driving. Review of Mt Yamnuska from a different perspective; preview of drive through McConnell damage zone and change in HW stratigraphy.. Stop 4: Lac des Arcs Imbricate thrust sheets in the Front Ranges and Banff Formation. Stop 5: Canmore T-junction Observe complexities of sub-seismic-scale deformation in mechanically layered rocks in the footwall of a large thrust Stop 6: Canmore strike view of the Rundle thrust Exposed strike view analogous to a cut-away of a giant conventional Foothills hydrocarbon field such as Turner Valley. Cross faults within the thrust sheet offset potential reservoir units at sub-seismic scale. Cross faults are arguably part of a regional trend associated with deeper, basement-rooted NE-SW structures. Stop 7: Mt Norquay Overlook Stop 8: Bow Falls Fracture systems in the Vega Siltstone Mbr of the Triassic Sulphur Mtn Fm. This outcrop of Vega Member siltstone of the Sulphur Mtn Fm is considered equivalent to upper Montney Fm. We will focus on the outcrop adjacent to the steps up to the Falls overlook.

In order to support the energy transition, optimizing exploration and production from complex stratigraphic-diagenetic conventional and unconventional plays remains highly important. At the same time, Carbon Capture and Storage (CCS) poses new technological challenges that will impact both the industry and academia for decades to come. This 2nd edition will present reviews and discuss technology developments in geological process-based forward modeling achieved during the last 2 years. New perspectives for future technology developments and implementation in industry workflows will be discussed and with the additional focus on CO₂ storage and other sustainability-related applications, the scope of the workshop will be considerably extended.

VG Abstract

In comparison with the known boundary conditions that promote salt deformation and flow in sedimentary basins, the processes involved with the mobilization of clay-rich detrital sediments are far less well established. This talk will use seismic examples in different tectonic settings to document the variety of shale geometries that can be formed under brittle and ductile deformations.

VG Abstract

Production from unconventional petroleum reservoirs includes petroleum from shale, coal, tight-sand and oil-sand. These reservoirs contain enormous quantities of oil and natural gas but pose a technology challenge to both geoscientists and engineers to produce economically on a commercial scale. These reservoirs store large volumes and are widely distributed at different stratigraphic levels and basin types, offering long-term potential for energy supply. Most of these reservoirs are low permeability and porosity that need enhancement with hydraulic fracture stimulation to maximize fluid drainage. Production from these reservoirs is increasing with continued advancement in geological characterization techniques and technology for well drilling, logging, and completion with drainage enhancement. Currently, Australia, Argentina, Canada, Egypt, USA, and Venezuela are producing natural gas from low permeability reservoirs: tight-sand, shale, and coal (CBM). Canada, Russia, USA, and Venezuela are producing heavy oil from oilsand. USA is leading the development of techniques for exploring, and technology for exploiting unconventional gas resources, which can help to develop potential gas-bearing shales of Thailand. The main focus is on source-reservoir-seal shale petroleum plays. In these tight rocks petroleum resides in the micro-pores as well as adsorbed on and in the organics. Shale has very low matrix permeability (nano-darcies) and has highly layered formations with differences in vertical and horizontal properties, vertically non-homogeneous and horizontally anisotropic with complicate natural fractures. Understanding the rocks is critical in selecting fluid drainage enhancement mechanisms; rock properties such as where shale is clay or silica rich, clay types and maturation , kerogen type and maturation, permeability, porosity, and saturation. Most of these plays require horizontal development with large numbers of wells that require an understanding of formation structure, setting and reservoir character and its lateral extension. The quality of shale-gas resources depend on thickness of net pay (>100 m), adequate porosity (>2%), high reservoir pressure (ideally overpressure), high thermal maturity (>1.5% Ro), high organic richness (>2% TOC), low in clay (<50%), high in brittle minerals (quartz, carbonates, feldspars), and favourable in-situ stress. During the past decade, unconventional shale and tight-sand gas plays have become an important supply of natural gas in the US, and now in shale oil as well. As a consequence, interest to assess and explore these plays is rapidly spreading worldwide. The high production potential of shale petroleum resources has contributed to a comparably favourable outlook for increased future petroleum supplies globally. Application of 2D and 3D seismic for defining reservoirs and micro seismic for monitoring fracturing, measuring rock properties downhole (borehole imaging) and in laboratory (mineralogy, porosity, permeability), horizontal drilling (downhole GPS), and hydraulic fracture stimulation (cross-linked gel, slick-water, nitrogen or nitrogen foam) is key in improving production from these huge resources with low productivity factors.

DL Abstract

For well over a century there have been conflicting indications of the strength of the crust and of faults and what controls them.  Much of our ignorance comes quite naturally from the general inaccessibility of the crust to measurement--in contrast with our understanding of the atmosphere, which is much more accessible to observation as well as more rapidly changing.  Crustal strength is best understood in deforming sedimentary basins where the petroleum industry has made great contributions, particularly in deforming petroleum basins because of the practical need to predict. In this talk we take a broad look at key issues in crustal strength and deformation and what we can learn from boreholes, earthquakes, active fault systems, and toy models.

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.

DL Abstract

Around 170 million years ago, the Gulf of Mexico basin flooded catastrophically, and the pre-existing landscape, which had been a very rugged, arid, semi-desert world, was drowned beneath an inland sea of salt water. The drowned landscape was then buried under kilometers of salt, perfectly preserving the older topography. Now, with high-quality 3D seismic data, the salt appears as a transparent layer, and the details of the drowned world can be seen in exquisite detail, providing a unique snapshot of the world on the eve of the flooding event. We can map out hills and valleys, and a system of river gullies and a large, meandering river system. These rivers in turn fed into a deep central lake, whose surface was about 750m below global sea level. This new knowledge also reveals how the Louann Salt was deposited. In contrast to published models, the salt was deposited in a deep water, hypersaline sea. We can estimate the rate of deposition, and it was very fast; we believe that the entire thickness of several kilometers of salt was laid down in a few tens of thousands of years, making it possibly the fastest sustained deposition seen so far in the geological record.

DL Abstract

Climate change is not only happening in the atmosphere but also in the anthroposphere; in some ways the former could drive or exacerbate the latter, with extreme weather excursions and extreme excursions from societal norms occurring all over the earth. Accomplishing geoscience for a common goal – whether that is for successful business activities, resource assessment for public planning, mitigating the impacts of geological hazards, or for the sheer love of furthering knowledge and understanding – can and should be done by a workforce that is equitably developed and supported. Difficulty arises when the value of institutional programs to increase equity and diversity is not realized.

DL Abstract

Paleozoic North America has experienced multiple mountain building events, from Ordovician to Permian, on all margins of the continent. These have had a profound effect on the resulting complex basins and their associated petroleum systems. Subsequent uplift, erosion and overprinting of these ancient systems impedes the direct observation of their tectonic history. However, the basin sedimentary records are more complete, and provide additional insights into the timing and style of the mountain building events. In this study, we employ ~90 1D basin models, ~30 inverse flexural models, isopachs, and paleogeographic maps to better understand the Paleozoic history of North America.

President Biden has laid out a bold and ambitious goal of achieving net-zero carbon emissions in the United States by 2050.  The pathway to that target includes cutting total greenhouse gas emissions in half by 2030 and eliminating them entirely from the nation’s electricity sector by 2035. The Office of Fossil Energy and Carbon Management will play an important role in the transition to net-zero carbon emissions by reducing the environmental impacts of fossil energy production and use – and helping decarbonize other hard-to abate sectors.
