Explorer Division Column DEG

The goal of the DEG this year is to increase the visibility of the Division in the areas of not only CCUS but also natural gas storage, hydrogen storage, compressed air energy storage and geothermal storage. Petroleum professionals are uniquely qualified to evaluate the risk and uncertainty of subsurface storage methods. We evaluate both containment risk, such as seal integrity and presence of faults, but also the impact of reservoir heterogeneities and reservoir properties on storage capacity.

Explorer Historical Highlights

In 1949 an historic oil field was discovered under the Caspian Sea. The field was named “Neft Dashlari, which in Azerbaijani means “Oil Rocks,” and it was a milestone in the development of the global oil industry. Oil Rocks, an iconic “city in the sea,” pointed the way to modern offshore drilling as we know it today.

Explorer President’s Column

Controversy can be a good thing, and sometimes, the more contentious things are, the better. Many great examples of this were discussed in my first geologic graduate course, the subject of which was “The History of the Science of Geology.” It was the controversy and debate itself that provided the greatest contribution to the science of geology – not the theories. Why is it important to recognize that controversy can be a good thing – important for AAPG and a good subject for my column in the EXPLORER? The answer is that controversy can also lead to the growth and improvement of a scientific society.

Some aspects of seismic interpretation, such as picking horizons and well-imaged faults, can be easily explained to a new interpreter. Other aspects, such as recognizing carbonate buildups, karst collapse, mass transport processes or volcanic intrusions, require not only an understanding of the underlying geologic processes, but also an understanding of their 3-D seismic data response. Although an experienced interpreter might be adept in using seismic data to map each of these features, they might also be challenged in explaining to the novice interpreter in a quantitative manner how they constructed their map or geobody.

We often see calls for the elimination of all petroleum products, including natural gas. As long as coal and biomass – which emit two-to-four-times more carbon than natural gas – are major components of electricity generation, it makes no sense to eliminate natural gas. Why would we blow up one of our cheapest, cleanest bridges toward the energy evolution when we are just starting to set foot on that bridge?

Depleted horizontal oil and gas wells could have a second life storing renewable energy, according to researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory. Because renewable forms of electricity generation like solar and wind require low-cost energy storage, the NREL researchers propose using depleted hydraulically fractured oil and gas wells to store electrical energy in the form of compressed natural gas to be released to spin an expander/generator when electrical demand is high.

Are years of upstream oil and gas underinvestment and under-exploration finally catching up with the world? Is the hope of avoiding a climate catastrophe now a lost cause? Can the global energy industry deliver adequate, affordable energy to meet the world’s future needs? Is the word in an energy crisis? Annually at midyear, a number of organizations publish overviews of the global energy picture. Based on those reports, there is good news. And bad news.

Mention energy from the Middle East and most people automatically think of crude oil production. But today, geopolitics and supply challenges have put an increased focus on global natural gas resources. Consequently, energy developments in the Middle East are shifting toward natural gas production and export, driven by an increasing international appetite for gas supply and questions about longer-term oil demand. Right now, the bottom line is that natural gas looks like a long-term growth industry and crude oil doesn’t.

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

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.

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

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.

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.
