The global shift from greenhouse gas-intense, carbon-based fuels toward alternative energy sources and technologies sometimes produces unintended negative impacts. Experts at the Bureau of Economic Geology at the University of Texas at Austin are mounting a major study of these effects – the Comparing Electricity Options research consortium – with the intention of helping to identify and mitigate such unintended outcomes.

In February, TotalEnergies announced a significant light oil discovery in the Orange Basin, offshore Namibia. Reuters reported a source suggesting that the Venus-X1 well may have found more than 1 billion barrels of oil equivalent. This was the second significant discovery announced in the basin that month. The offshore continues to deliver new oil and natural gas discoveries worldwide. And as this issue hits your inbox, the offshore is the primary topic of discussion in Houston as the 2022 Offshore Technology Conference returns to NRG Park from May 2-5.

Explorer Foundation Update

Geoscience education is essential to the AAPG Foundation. In fact, it’s promised right there in the Foundation’s mission statement, to “… support(ing) education and scientific activities in the field of geology.” Also crucial to the Foundation: engaging and informing the general public about the importance of energy, geology and the world in which we all reside. That’s why there are many, many Foundation programs supporting all those goals. But some Foundation-backed projects exist to do both at the same time – and one, in particular, is making a big impact on both students and the public by merging geology, geosciences and video production techniques into one informative, often timely and always accessible package.

Listening to “King of the Mountain” by Midnight Oil, a song about a foot race up the wickedly steep Mount Cooroora in Australia, prompted me to think about whether it is good to be the king, or to be in a position to just help others get to the top of the mountain. We do not need royal powers or superhuman running ability to make a difference for people participating in AAPG activities. Making a difference can be much simpler and just requires the will to make the climb and help others along the way.

The challenges in acquiring quality laboratory flow measurements in very low-permeability reservoir rock samples has furthered the development of image-based rock physics simulations of multiphase transport properties. The concept of “digital rocks” originated 50 years ago and has become more widespread recently with advances in imaging technology, computing power and robust algorithms for representing complex multiphase flow behavior at the pore scale. Simulation results based on high-resolution images have the dual role of complementing laboratory measurements on conventional reservoirs and acting as a stand-alone predictive tool for unconventional reservoirs where the very low permeability values limit what can be measured in the laboratory.

Explorer Historical Highlights

There are two main oil and gas producing sedimentary areas in France: the Paris Basin and the Aquitaine Basin. The presence of oil seeps and bitumen deposits has been known since ancient times in the western part of the Aquitaine basin, a 35,000-square-kilometer triangular polygon bordered to the north by the city of Bordeaux, to the east by Toulouse and to the south by the Pyrenees Mountain chain separating France from Spain. These hydrocarbon shows were observed close to surface anticlinal structures such as the Sainte-Suzanne dome, southwest of Pau or in the caprocks of salt diapirs at Salies de Bearn and Dax to the north.

In the first part of this series, we showed the energy transition will follow an “all of the above” trajectory, irrespective of aspirational messages. Our conclusions are based on the inherent limitations of wind and solar low-density energy machines for generating base-load power: low-density energy machines would cover hundreds of millions of acres. Also in part 1, we discussed Princeton University’s Net Zero America report, an outstanding, 18-author study of five models to de-carbonize the United States by 2050.

What seemed like excellent news for the oil and gas jobs outlook turned into something less positive for companies in the first months of 2022. Hiring increased, but a few areas saw more openings than applicants. However, job hunters and even those already employed in oil and gas got some welcome security and relief, as recent cycles of industry layoffs finally turned into a round of rehires and new hires. Analysts expect this job growth to continue for the foreseeable future.

Located in the Orange Basin, along the passive west coast of the continental margin that straddles the borders of South Africa, there has been a discovery of an oil province in Namibia – the offshore Graf and Venus fields – that likely contains billions of barrels of oil resources. That’s according to Robin Sutherland, an exploration manager for Monitor Exploration, a UK-based private exploration company involved in oil and gas exploration in Africa. Of equal importance, he said, is the recent drilling by ReconAfrica, which “clearly proves” that the Ovambo Basin, a large pre-Cambrian basin in the far north of Namibia, is oil bearing with very significant potential. “Both of these events represent major changes to our understanding of the potential of Namibia,” said Sutherland.

Field Trip Leaders: Jean Borgomano – CEREGE, Aix-Marseille Université, France Michele Morsilli – University of Ferrara, Italy Fees: €450 + VAT Fee Includes: Transportation during the field trip Overnight Accommodation Breakfast, lunch 2 days and dinner Themes The Gargano Promontory (southern Italy) offers the opportunity to investigate a complete carbonate facies transect from inner platform to basin and to reconstruct the various events that shaped and controlled the evolution of the Apulia Carbonate Platform during the Cretaceous and Paleogene. This area can be considered a wonderful outcrop analog to better understand and visualize facies, depositional geometries, stratigraphic relationships and to compare them with other carbonate platforms. The exposed carbonate rocks show well-preserved original reservoir properties and form relevant analogues of subsurface reservoirs located in different structural settings; e.g. inner platform palaeokarst (Ombrina Mare, Rospo Mare oil fields), subthrust setting (Monte Alpi, Tempa Rossa), slope, base-of-slope resedimented carbonate facies (Elsa, Miglianico, Aquila, Rovesti), as well as relevant for the comparison with the specular Adriatic Carbonate Platform (AdCP) or other Tethyan carbonate systems. Main goals of this field trip are the observation of the facies and stratigraphic architecture of the inner platform and of slope and base-of-slope units deposited during the Early - Late Cretaceous and Eocene, as well as the carbonate production and exporting/resedimentation processes. The Apulia Carbonate Platform represents a well-known case study of a carbonate platform with different evolution through time. Facies distribution from inner platform to base-of-slope, stratigraphic architecture and depositional geometries, together with retreat and drowning of the platform or margin collapses, and seismic-scale outcrops, in a relatively poorly deformed context, constitute a text book examples of a Cretaceous Carbonate System. Itinerary and Stops Day 1 Naples (or Bari airport) to Apricena by bus (travel about 3 h) Stop 1.1 - Apricena quarries district: stop on peritidal cycles of Lower Cretaceous, fractured and karst reservoir (outcrop analog of the Rospo Mare oil field).

The petrophysical characterization of unconventional shale-type reservoirs has been one of the most approached and relevant issues in the oil and gas industry in the last 8 years. This is because after several years, the operating companies comprehended the impact that an appropriate characterization of the reservoir has on their project economics. Another reason for this were the technical obstacles encountered in the measurement of petrophysical properties such as porosity, saturation and permeability due to the complexity of this type of reservoir. Obstacles and limitations not only relate to laboratory measurements but also to electrical logging tools. As a consequence of this, nowadays, petrophysical evaluations in this type of reservoir do not have standardized workflows established and accepted worldwide as is the case for conventional reservoirs. This motivates the professionals involved in the study of this type of rocks to dedicate a lot of effort in the validation of the technologies used, and sometimes it is difficult for them to understand the results, the evaluation of uncertainties and the construction of petrophysical models with results and representative parameters of the subsurface conditions. This course will focus on providing key knowledge for a better characterization of the rock both in the aspects related to the matrix represented by mineralogy and kerogen as well as the fluids present. The approach will be based on the convergence of different technologies that support and give robustness to the results. The contents that will be provided will include laboratory testing techniques and petrophysical evaluation of electrical well logs for unconventional shale-type reservoirs. The contents provided will cover a variety of studies based on the most diverse physical principles that will include the latest advances and techniques used in the industry such as Nuclear Magnetic Resonance, Spectroscopy, Dielectric, Computed axial tomography and SEM images, among others. As a result of this, attendees will have tools that allow a more comprehensive understanding of this type of rocks, a better assessment of the uncertainty of the model used and the necessary steps to improve its precision, accelerating the learning curve. The contents provided will also allow knowing the critical parameters that must be taken into account for the definition of areas to be drilled. Course Topics Reservoir heterogeneity characterization from outcrops to lab data and electrical logging. Most relevant unconventional plays of the world. Main characteristics.

Modelling carbonate sequences and reservoirs has always been a challenging task. Carbonate rocks are generated and subsequently modified by a large variety of biological, physical and chemical processes that start at the time of deposition and end today. To unravel the geological evolution and history of carbonate sequences is fundamental not only for understanding their hydrocarbons potential but also for their role as potential reservoirs for renewable energy (geothermal) or geological gas storage (CO2 and hydrogen). Several science disciplines are often involved to fully understand the characteristics of carbonate rocks and old approaches and new technologies and tools are nowadays applied in these types of sequences. The objective of this meeting is to allow scientists and engineers working on carbonate rocks in academia and industry to share their most recent experience, work, approaches and use of innovative technologies to increase the understanding of the very complex world of carbonates.

Trip leader(s): Josep Anton Muñoz, Pablo Granado and Eduard Roca Limit: 20 Participants The aim of this 2-day field trip is the recognition of the key structural features of a fold and thrust belt detached on salt that has resulted from the inversion of a previous passive margin. To achieve this objective, some of the key and most spectacular localities of the southern Pyrenees have been selected along the ECORS-Pyrenees transect. This is a reference cross-section provided that for many years a huge amount of geological and geophysical data sets has been collected and integrating into a kinematic model of the South-Pyrenean fold and thrust belt. Subsurface data (well logs and seismic sections) will be combined with field observations. One of the main characteristics of the southern Pyrenees is the preservation of the synorogenic sediments since the earlier stages of deformation, which not only provide time constraints but also allow us discussion of kinematics of fault-related folds and thrust systems. Finally, the mild contractional deformation permits deciphering the initial geometry of the rift system and the salt structures that configure the structural grain of the passive margin before the inversion, allowing discussion of the role that these structures play during the fold and thrust belt development. Itinerary: (day by day details of the trip) Day 1 Stop 1.1: The South-Pyrenean thrust front. Sant Llorenç de Montgai Structure of a frontal thrust system and related unconformities. Out of sequence thrusts and synorogenic sediments. The frontal thrust system of the South-central Pyrenees has been detached into the Triassic evaporites and involves a thin Mesozoic succession. It is characterized by an emergent thrust system during the sedimentation of upper Eocene and lower Oligocene continental sediments. Frontal thrusts were progressively buried by conglomerates, triggering a break-back thrusting sequence and the development of out-of-sequence thrusts bringing together strongly different Mesozoic successions, such as the Montroig thrust in the picture. Stop 1.2: The Ager basin and the Montsec thrust sheet. Fontllonga The Ager basin in the footwall of the Montsec thrust. The Montsec thrust sheet developed from the Paleocene to the Early Eocene as recorded by continental to shallow marine sediments deposited in its footwall (Ager basin) as well as in the Tremp-Graus piggy-back basin. The lower Eocene sediments of these basins grade westward into the slope succession filling the Ainsa basin at the footwall of the Montsec thrust. Stop 1.3: The frontal structure of the Montsec thrust sheet. Ametlla (optional: Montrebei) Fault-propagation fold related with the inversion of Early Cretaceous extensional faults and growth deltaic sediments in the footwall syncline. The Montsec thrust sheet involves the northern part of the Upper Cretaceous foreland basin characterised by a strong subsident turbiditic trough at the footwall of the Bóixols thrust. These turbidites grade southward into a carbonatic platform that constitutes the backbone of the Montsec Range (main ridge and cliff of the pictures). Underneath the Upper Cretaceous carbonates, some Early Cretaceous extensional faults are preserved in the hanging wall of the Montsec thrust, but others have controlled the development of a hanging wall frontal anticline. The geometry of this anticline as well as the structure of the growth sediments in the footwall Ager syncline are visible in the field. The subthrust geometry will be discussed integrating surface observations and the available seismic and well data. Overnight in Tremp Day 2 Stop 2.1: The Sant Corneli-Bóixols anticline Inversion of the rift margin The Sant Corneli-Bóixols anticline is the most prominent frontal structure of the Bóixols thrust sheet in the central Pyrenees. This fold trends east–west and crops out for greater than 40 km along strike. The Sant Corneli-Bóixols anticline involves a thick Mesozoic succession detached on top of Triassic evaporites. The prefolding sequence consists of up to 5 km of prerift, synrift, and postrift carbonates ranging in age from Jurassic to Upper Cretaceous. Synfolding Upper Cretaceous sediments start with the upper Santonian carbonates and continue with a succession of Campanian and Maastrichtian marls and turbidites. The Sant Corneli–Bóixols anticline is an example of an inversion fold developed along the rift margin of the Lower Cretaceous basin. Its geometry is related with the inverted extensional system. In particular, the three-dimensional geometry, including the saddles between culminations, is inherited from the previous transfer faults of the segmented rift margin. Available seismic data and 3 exploratory wells constrain the geometry at depth. Stop 2.2: The synororgenic Paleogene conglomerates Inverted Lower Cretaceous basin and Eocene-Oligocene synorogenic conglomerates at Collegats gorge. Stop 2.3 (optional): The Sopeira and Aulet minibasins. Sopeira Minibasins developed by extensional collapse and salt evacuation during the thermal subsidence at the southern Pyrenean rift margin. Inversion of these mini-basins at the early stages of Pyrenean contractional deformation during Late Cretaceous. Additional logistic information Transportation Transportation will be with a small bus, assisted by minivans to have access to some of the outcrops. Physical demand, equipment and safety This is an easy field trip with very easy and limited hikes to get to the outcrops. Outcrops will be from main sealed roads. Safety vests will be available, to be used by everybody of the group wherever required and asked to. There will be First Aid Kits available in each car during fieldwork. Climate The climate during mid-end November in the fieldwork area can be cold and rainy, although dry and sunny days may occur as well. The temperature for November in Tremp can range between 30C and 170C. Participants should be prepared in case we should encounter bad weather and you should bring warm and waterproof clothes and suitable hiking boots. -->

He will share some of the true costs of managing large data sets in the cloud and why it doesn’t add significant business value. In the same way that lifting and shifting legacy tools and services to the cloud yields little value, moving seismic data to the cloud also yields little value. It isn’t until applications, workflows and even the data storage formats are re-engineered that real business value and even cost saving can be found.

VG Abstract

Microseismicity induced by hydraulic fracture stimulation of a horizontal well was mapped with a near-surface buried array. Distinct linear trends of events were not parallel to the direction of fast shear wave polarization measured in the reservoir with a crossed-dipole anisotropy tool. Analysis of core from a nearby well revealed numerous calcite-filled fractures that did not induce shear wave polarization, but did significantly impact the failure behavior of the reservoir rock during the stimulation treatment. Hydraulic fracture simulation with DFN modeling and source mechanism analysis supports the interpretation of reactivated existing fractures rather than the formation of hydraulically-induced tensile fractures.

VG Abstract

Analysis of microseismicity induced by hydraulic fracture stimulation in the Marcellus Shale shows changes in stress state for different zones of failure. During the treatment, shear failure occurs on both the J1 and J2 fracture orientations in response to different maximum stress orientations, indicating localized changes in the orientation during the treatment. Reactivation of a fault near the wellbore is associated with failure mechanisms with a higher volumetric component, indicating possible inflation of faults and fractures by the introduction of the slurry. Quantification of the stress conditions that are associated with inflation could potentially be used to optimize the stimulation by identifying which fractures will preferentially take on slurry volume.

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 1991, Gulf Indonesia and its partners discovered South Sumatra Basin’s first major gas field at Dayung in the Corridor PSC. A key feature of this field is that most of the reserves are held within fractured basement rocks of pre-Tertiary age.

VG Abstract

This lecture will discuss the differences between carbonates and siliciclastics from their chemical composition through their distributions in time and space. Building on these fundamental differences, we will explore the challenges carbonates pose to petroleum geologists in terms of seismic interpretation, reservoir quality prediction, field development, etc. Peppered with humorous personal stories, still raging academic debates, and the heartfelt frustrations of real industry professionals, the aim is to inspire students and young professionals to rise to the occasion and embrace the reservoir rocks that petroleum geologists love to hate.
