Scott Tinker, director of the Bureau of Economic Geology at the University of Texas at Austin, will grant no quarter about either the history and benefits of energy in our lives or its potential to improve our future. “Access to affordable, reliable energy is the foundation of modern economies,” he said. This subject has been on his mind of late, for he has spent the last two years studying those who are, as he puts it, suffering from “energy poverty.” Some 2.5 billion people worldwide live in some form of energy poverty today. “Access to secure energy,” Tinker said, “impacts all other major humanitarian issues, including hunger, shelter, clean water, education, healthcare, human migration, empowerment of women, and more. Those who do not have energy access suffer from energy poverty.”

Take a look at many of the major energy companies’ websites and you’re likely to see a “New Energies”-section with an outlined commitment for ultimately achieving “net zero” carbon emissions. Shell, for example, has increased the number of employees in its New Energies sector from 60 to 800 in the past two years. However, when looking at the world’s energy leaders, none have agreed on a clear path forward.

Talk of mitigating carbon footprints is growing louder. Regardless of differing views on the carbon issue, many in the oil and gas industry and beyond are beginning to make changes not only to be better stewards of the environment, but to protect business from growing public and investor sentiments against fossil fuels. Public opinion is now infiltrating investor sentiments and the industry needs to adopt significant changes that will keep the public and investors on board.

The end of the year is popularly depicted as a grizzled old man, stooped under the care and worry of the year gone by, ready to relinquish his responsibilities and pass the baton to the rosy-cheeked, diapered baby crawling expectantly into a new year. I’m not sure if this depiction is true this year, because I’m not sure where 2019 went – it feels like we barely got out of adolescence. And now, here we are, beginning anew. Happy New Year!

In the arena of super basins, what’s old is new again. With new technology, oil finders are finding great success by returning to basins once thought to be mature. While exploration continues along new frontiers, the industry has returned to the world’s richest petroleum-bearing basins with an all-out effort to optimize extensive infrastructure using new technology.

Seismic attributes help enhance the subtle subsurface geologic detail that might be difficult and time consuming to decipher from 3-D seismic amplitude data. Beginning with the simple computation of envelope, phase and frequency attributes in the 1970s, several dozen seismic attributes are generated these days containing disparate types of information. To bring together all this information and produce an accurate subsurface model, the multiple attributes need to be carefully visualized and displayed, and thus has become an important interpretation tool for seismic interpreters.

The sedimentary basins of the Middle East have been proved to contain vast hydrocarbon reserves, sourced by some of the most prolific petroleum systems in the world. This is the product of a range of factors, not least the long-lived, relative stability of the Arabian Plate and the presence of multiple, prolific organic source rocks. This workshop will address these and other subjects and to discuss the main challenges present in our current understanding of petroleum systems in the Middle East.

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.

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.

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

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.

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.

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.
