Coherence and curvature attribute computations are usually carried out on stacked seismic data volumes to delineate faults, flexures and large fractures. If the vertically-aligned parallel fractures in the subsurface are filled with fluid, or weakly cemented, the P-wave velocity across the fractures will be slower than that parallel to the fractures. These differences give rise to a velocity variation with azimuth. Because impedance is the product of density and velocity, such fractures also give rise to amplitude variation with offset.

Explorer Historical Highlights

The search for new sources of helium is of paramount importance as a combination of declining production and increasing demand have made helium prices soar. This follows a century in which the United States had a near monopoly on helium reserves and U.S. production met global demand. Although most of the helium production story has taken place in the United States, there are other nations that have produced and are producing helium.

Time: TBC Attendee Limit: Minimum 15 - Maximum 50 People Fee: TBC Registration Deadline: TBC Field Trip Rendezvous Point Hotel nH Palermo 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.

Sunday, 21 April 2024, 8:00 a.m.–5:00 p.m.

Time: TBC Attendee Limit: Minimum 15 - Maximum 45 People Fee: TBC Registration Deadline: TBC This one-day field trip will focus on Mesozoic (Jurassic to Cretaceous) carbonates outcropping in the fold and thrust belt of western Sicily and equivalent to the aquifer complex of the Sciacca Geothermal Field located in the southwestern part of the island. Participants will have the opportunity to visit in the first stop a spectacular “drowned” carbonate-platform succession at Mt. Maranfusa located in an inactive quarry about 50 km SW of Palermo. The succession consists of Lower Jurassic peritidal cycles overlain by Middle Jurassic to Cretaceous pelagic limestone (e.g. ammonitic limestone, “chalk”) and marked by an unconformity with locally hardground. Syn-depositional Mesozoic tectonic is characterized by neptunian dykes and normal faults, whereas reverse faults, strike-slip faults, and joints are related to subsequent Cenozoic deformation. In the second stop, at Mt. San Calogero, adjacent to the picturesque coastal town of Sciacca (about 100 km south of Palermo), we will visit the surface expression of an extensive karst system linked to uprising geothermal fluids. Furthermore, we will discuss main characteristics of the Sciacca Geothermal Field and its connection to deep mantle-derived fluids. Outcrop data will be integrated with both 2D seismic lines and exploration well logs showing the stratigraphy and structure of the deep aquifer. Another topic, given the presence of faults and joints in the outcrops, this field trip can provide the participants with valuable insights into naturally fractured reservoirs at the sub-seismic scale.

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.

DL Abstract

While there are many habitats that are associated with the deposition of organic-rich marine and lacustrine source rocks, one important pathway is linked to the onset of increased basin subsidence associated with major tectonic events. A key aspect is that this subsidence is spatially variable, with the uplift of basin flanks contemporaneous with the foundering of the basin center, resulting in a steeper basin profile.

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

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

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.

Local sea-level changes are not simply a function of global ocean volumes but also the interactions between the solid Earth, the Earth’s gravitational field and the loading and unloading of ice sheets. Contrasting behaviors between Antarctica and Scotland highlight how important the geologic structure beneath the former ice sheets is in determining the interactions between ice sheets and relative sea levels.
