“Undoubtedly, yes, the world must accelerate its transition to renewable energy. Cost is no longer a major barrier for renewables.” That’s Sir Mark Moody-Stuart, chairman of the United Nations Global Compact Foundation, an organization dedicated to finding what it calls “lasting solutions” to the world’s pressing global needs, including, for our purposes here, energy.

While many see the energy transition as the switch from carbon-based to non- carbon-based fuels, Scott Tinker sees a broader definition. Tinker, past AAPG president, director of the Bureau of Economic Geology and Texas state geologist, suggested the goal of a successful transition is lifting some 2.5 billion people out of poverty by addressing energy poverty, as well as by minimizing environmental impacts.

These days acoustic and elastic impedance are commonly derived from 3-D seismic data, which help us compute porosity and reservoir fluid estimates. Somewhat less commonly, vertical fracture density and fracture orientation in the reservoir rocks are derived from seismic data, enhancing our ability for optimum placement of horizontal wells and optimal recovery. To achieve the latter objective, good quality seismic data are required, which might be acquired not only with such objectives in mind, but also to yield data with good signal-to-noise ratio.

Explorer Historical Highlights

I was once asked during a job interview, “Is geology a science or an art?” I am still wondering what the correct answer is to something that sounds like a trick question, but what I do know is that both scientists and artists require inspiration. This can come in all manner of forms, but we can definitely be inspired by those who have paved the way for our ongoing endeavors. For our profession, that means being inspired by the great geologists. The history of geoscience is marked by the work of exemplary scientists who changed the way we think about the Earth, its history, processes and resources.

Collaboration. Scott Singleton, geophysical technology adviser at Independence Resources Management in Houston, wants to underscore that one word. He believes that if there’s a single ingredient to success in unconventional fields – and the one concept from which those in unconventionals have unfortunately moved away – it’s that geologists, geophysicists and engineers have to work together for the benefit of everyone.

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.

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.

Three-dimensional (3D) seismic-reflection surveys provide one of the most important data types for understanding subsurface depositional systems. Quantitative analysis is commonly restricted to geophysical interpretation of elastic properties of rocks in the subsurface. Wide availability of 3D seismic-reflection data and integration provide opportunities for quantitative analysis of subsurface stratigraphic sequences. Here, we integrate traditional seismic-stratigraphic interpretation with quantitative geomorphologic analysis and numerical modeling to explore new insights into submarine-channel evolution.

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.

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.
