Thanks to continuing advances in reservoir characterization, technology and innovative thinking, many oil fields around the globe have “grown larger” in recent decades. John Sneider, president of Sneider Exploration Inc., documented examples of mature field growth 20 years ago and recently revisited the topic to focus on mature giant fields. This updated analysis is detailed in chapter 4 of the new AAPG Memoir 125: “Giant Fields of the Decade: 2010 – 2020.”

Before unconventional resources became prevalent in the global petroleum supply, deepwater exploration and development was a significant focus for many larger companies. For deepwater activities to succeed, the petroleum industry was forced to merge its above-ground concerns with the below-ground geoscience and engineering disciplines.

What is “unconventional wisdom?” It’s the wisdom obtained from half a century of important conferences organized by the AAPG Eastern Section, founded in 1971, which recently celebrated at its 50th annual conference in Pittsburgh. The Pittsburgh Geological Society, founded in 1945, co-hosted the conference with the Pittsburgh Association of Petroleum Geologists, created in 1984. “The theme ‘Unconventional Wisdom’ is intended to reflect not only the unconventional resources and reservoirs that have brought life to the Appalachian basin, but also to appreciate the broad heritage of our science and vocation,” said conference General Chair John Corbett.

Natural gas was first commercially discovered in the San Juan Basin of New Mexico in 1921, making this year the Basin’s centennial. The first San Juan Basin natural gas strike occurred one mile south of Aztec, N.M., when the Aztec Oil Syndicate completed their No. 1 State. Production was found at a depth of about 1,000 feet. The gas discovered south of Aztec was piped into town and used domestically throughout most of the 1920s. This was the first commercial use of natural gas in New Mexico or the San Juan Basin. Located in northwest New Mexico and southwest Colorado, the San Juan is one of the largest gas basins in the United States, along with the Marcellus in the Appalachian Basin and the greater Hugoton Field of Texas, Oklahoma and Kansas.

It has become something of an old chestnut in the West that China will often claim to have achieved famous scientific advancements and inventions first, often hundreds of years before the West. The investigation of these sorts of disputes – and deciding who gets bragging rights – is probably best left to serious historical researchers, but there is firm evidence of many interesting early technical achievements from the Middle Kingdom. Ancient China’s development of deep drilling techniques predates similar advancements in the West by hundreds of years.

Increasing global concern about climate change and its impact on the environment and society has led to a variety of strategies to reduce carbon dioxide emissions and to remove CO₂ from the atmosphere and find places to store it. Many companies are hard at work to perfect methods of carbon capture, use, and storage. Franek Hasiuk, associate scientist at Kansas Geological Survey, said CCUS is the best technology available to reduce emissions produced by the global economy. Hasiuk is part of a team of scientists working on the Integrated Midcontinent Stacked Carbon Storage Hub, a project to investigate subsurface geology in southwest Kansas and southwest Nebraska and demonstrate the viability of injecting CO₂ into underground rock layers.

Workshop
Muscat, Oman
Monday, 16 January Wednesday, 18 January 2023, 8:00 a.m.–5:00 p.m.

By investigating petroleum systems, we can potentially reduce the risk of hydrocarbon charge and help define the commerciality of potential prospect and leads. Predicting oil versus gas, making predictions on oil quality or condensate-gas ratio can allow informed decisions to be made pre-drill. Advances have been made in the recent past to address subjects as diverse as, non-hydrocarbon gases, the potential for unconventional hydrocarbons, the role of hydrodynamics, the presence of tilted fluid contacts, the formation of microbial gases, phase prediction and in-reservoir fluid alteration processes. The purpose of this workshop is to address these and other subjects and to discuss the main challenges present in our current understanding of petroleum systems in the Middle East.

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. The petrophysical model. Components and definitions, construction, uncertainties, strengths and weakness. Lab studies: porosity, saturation, mineralogy, organic geochemistry and permeability.

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.
