The energy transition has been getting so much press that a hypothetical visitor from Mars could be forgiven for believing it will be completed “by next Tuesday.” Some universities and organizations are dropping any mention of petroleum in the interest of appearing forward-looking. We see this as timely folly based on a lack of historical perspective. History shows that energy transitions are lengthy and complicated. They never follow a prescribed path; they wander down dead-ends and evolve with pragmatic solutions unforeseen today.

As the United States looks for ways to decarbonize its energy sources, some believe the nation’s abundant gas reserves – estimated at 495 trillion cubic feet in 2019 by the U.S. Crude Oil and Natural Gas Proved Reserves – can play an important role. Using the steam methane reforming process, the numerous petrochemical plants along the Gulf Coast are the No. 1 producers of hydrogen in the nation. Because this hydrogen is produced with a CO2 byproduct, it is not considered a clean energy. However, by integrating carbon capture, utilization and storage into the SMR process, a clean form of hydrogen could be produced and used for process heating, in gas turbines that generate electricity, in shipping vessels and in the petrochemicals industry.

Many members of the Energy Minerals Division are researching or working to develop non-fossil energy resources, including geothermal, critical and nuclear minerals, and some “colors” of hydrogen, all in service to human civilization’s ongoing energy transition. Over the years, there has been a variety of reasons given for why the current transition is necessary. These are very real and important concerns, but what often gets left out of the public discourse on the energy transition is how complex and disruptive it will be, especially if we’re going to meet any of the ambitious goals set for this century.

Last month I wrote about the substantial increases in E&P investment necessary to ensure the availability of oil and gas supplies in the future to reduce price volatility and enhance global energy security. I drew on the analysis in a recent report of the International Energy Forum and IHS Markit. Business activity and investment in E&P remains on my mind this month, as I look forward to the upcoming NAPE Summit, from Feb. 8-11, at the George R. Brown Convention Center in Houston.

The cloud forests in Western Colombia’s Andes Mountains are home to a diverse group of indigenous communities including the U´wa people. Community traditions prohibit members from using energy from non-renewable sources, so most lack access to electricity. Without computers and the internet, U’wa children’s education lags behind that of other Colombians. The story changed for one U´wa village when a group of geology students and AAPG Chapter members decided to reach out.

Last month Houston hosted the 23rd World Petroleum Congress with more than 5,000 attendees from 70 countries. After a one-year postponement due to the global pandemic, energy leaders from across the globe gathered to discuss the future of energy. And the tone of the discussion was sobering. Following on the heels of November’s COP26 meeting in Glasgow, there was recognition that political and societal pressures are shifting the energy sector and the industries in it. But there was widespread concern that the expectations underlying these pressures for change were unrealistic. That those pushing hardest for change lacked a fundamental understanding of what transforming the global energy sector truly entailed, what it would look like when it was complete and the dangers looming from getting it wrong.

The estimated hydrocarbon reserves around the world, when produced, can keep us going for the next several decades. But scientific records and our own experiences are enough evidence that climate change is indeed happening. Addressing it requires energy extraction from non-fossil fuels. One such resource is the natural heat of the Earth, or geothermal energy.

Producers finally got some relief in 2021. Oil and gas prices recovered from their pandemic lows and remained at high levels through most of the year, as increased production could not keep pace with a global demand recovery. It was a year when higher prices helped energy producers strengthen their balance sheets and improve their bottom lines.

Technological advances in the geothermal energy sector are making some geoscientists hopeful about the potential to deliver its energy resources almost anywhere on the planet. The growing need for clean, resilient, baseload energy coupled with recent advancements in oil and gas technology have prompted geoscientists to push the boundaries of geothermal resources. Looking beyond the natural settings of the resource, geoscientists are working to bypass geographic and geologic limits so that geothermal energy can be used around the world.

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.

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.

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.

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

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.

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.

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.
