As geoscientists, we are predisposed to associative thinking. Trained for pattern recognition by our education and experiences, we have learned to recognize familiar elements in a new dataset and integrate those pieces of information into a subsurface geological model. However, this learning system is usually biased and most of the time we are unaware of it. With the increasingly common use of machine learning in our workflows to bolster human interpretation, we must become increasingly aware of our biases, so that they they can be minimized as we train the algorithms. Herein is a case study and bias discussion from the Ceará Basin in Brazil, where deep convolutional neural networks are used to aid in the petrophysical analysis and volumetric assessment of a potential reservoir.
To most outsiders in the 1950s, the Buraimi Affair was a passing curiosity, a faraway squabble about territorial rights in a remote corner of southeast Arabia known as the Buraimi Oasis. The British government backed its protégés, Abu Dhabi and Oman, against Saudi Arabia, while the United States government took a mediating role. However, as the Time magazine report suggested, there was another aspect to the dispute: it was rumoured that Buraimi was “floating on a pool of oil.”
For decades, reservoir characterization has played a crucial role in oil and gas projects – in identifying and extracting hydrocarbons from the subsurface. Now, some geologists and geophysicists are applying their industry expertise to the emerging fields of carbon storage and geothermal energy.
Facing a challenging situation and low demand, geophysical companies found themselves in a hole after the energy industry’s latest, coronavirus-related downturn. They’ve been trying to dig themselves out for the past year. The good news is, that effort now appears to be working, as higher oil prices begin to have an effect and more positive signs emerge in the second half of 2021.
An historic book is being reopened, and the next chapter in AAPG’s ongoing efforts to recognize, offer and promote geoscience excellence around the world is about to be written. Six diverse and internationally acclaimed geoscientists have been announced for the 2021-22 AAPG-AAPG Foundation Distinguished Lecture season – speaking on a spectacular range of subjects that vary from understanding integrated hydrocarbon systems to utilizing machine learning to recognizing the importance of choices in today’s energy transition.'
'The geobody tool provides a means for an interpreter to rapidly visualize the extent and orientation of anomalous geologic features of interest. However, the last decade has seen an exponential growth in both the number and size of 3-D seismic surveys. Augmented by multiple attribute volumes for each survey, these large data volumes provide both an aid and a burden on the interpreter, whose goal is to wade through all these data with the goal of extracting patterns that correlate to a geologic model, which can then be used for oil and gas exploration and development.
As many of the world’s oil and gas resources lie beneath the oceans, the advances in exploration, drilling and production technologies have also focused in those areas.
“Geologists and geophysicists work well together.” That’s Stephen A. Sonnenberg on why AAPG and the Society of Exploration Geophysicists will be coming together for the International Meeting for Applied Geoscience and Energy at the Colorado Convention Center in Denver and online, Sept. 26 through Oct. 1. This year’s inaugural hybrid event will include nearly 200 technical presentations, 14 workshops, 10 special sessions, five field trips, numerous networking opportunities and a joint exhibition showcasing the latest geoscience products and technologies will be on hand.
The International Meeting for Applied Geoscience and Energy, or IMAGE ’21, the integrated annual convention of AAPG and the Society of Exploration Geophysicists in conjunction with the Society for Sedimentary Geology, is all set for its inaugural event to be held online and in-person in Denver, Colo., Sept. 26 to Oct. 1. This gathering of the industry’s top thinkers, leaders and innovators boasts an impressive schedule of special sessions, workshops, field trips and other offerings to expand geoscience and professional skills.
Overall, machine learning has introduced us to a whole different world that has taken geoscientists by surprise. However, the real question is how much can we trust the machine? How accurate can it be? And the most intriguing question of all – can machine learning replace the interpreter? We will analyze three machine learning processes to assess the pros and cons of utilization of convolutional neural networks for fault prediction versus interpretations made by the user in a highly complex polygonal fault section of a 3-D seismic reflection dataset.
Blending of seismic attributes with additive primary colors is a standard visualization procedure used by interpreters to integrate the information contained in them and carry out comprehensive interpretation. In the December 2019 and February 2020 installments of Geophysical Corner, we described how color is perceived by the human eye, and how colors are rendered on interpretation workstation monitors. We also described the additive RGB color model which forms the working model for computer monitors, as well as the subtractive CMYK model and the HSV and HSL color models frequently used for covisualizing seismic attributes.
This course is informed by over 20 years working in oil and gas exploration and production with many companies and clients and by a further 15 years teaching structural and petroleum geology at Universities in Australia.
This presentation will show where there are cases of missing sections, but none of them can be attributed to normal faulting.
This study will focus in the combination of λρ – μρ inversion with clustering analysis techniques in order to discriminate brittle zones in the Barnett Shale.
Visiting Geoscientist Juan Pablo Lovecchio reviews general aspects of rifting, rifts and passive margin formation and evolution through time, as well as elements of petroleum system development.
This course is ideal for individuals involved in Midland Basin exploration and development. Successful development of Wolfcamp shale oil relies on complex inter-relationships (ultimately interdependencies) within and between a wide variety of scientific disciplines, financial entities, and company partnerships.
This presentation will focus on the seismic stratigraphic and seismic geomorphologic expression of deep-water deposits, including both reservoir and non-reservoir facies.
The Eagle Ford Shale in South Texas is one of the more exciting shale plays in the United States at the current time.
Thulisile Sopete explores the sedimentary evolution of the Pletmos Basin. The Pletmos Basin is a sub-basin of the greater Outeniqua Basin, is located off the south coast of South Africa and is bounded by the Bredasdorp Basin to the west, the Gamtoos Basin to the east and the Southern Outeniqua Basin to the south.
The approach applied in the analysis for this study was based on five selected seismic transects which were interpreted using seismic stratigraphy. These interpretations were incorporated along with composite logs analysis for their respective wells to provide the framework in understanding how the Pletmos Basin evolved sedimentologically.
There are approximately 1,000 oil and gas fields in the world that have been classified as 'giant,' containing more than 500 million barrels of recoverable oil and /or 3 trillion cubic feet of gas.
This e-symposium will provide information on which tools, processes, and procedures all geoscientists, engineers, and technical professionals working in shale plays need to understand and implement.
Visiting Geoscientist Mauricio Guizada provides an overview of general structural geology of the Andes, with a focus on the Central Andes. His talk covers topics related to onshore exploration, G&G methods in exploration and risk analysis. Join Mauricio Guizada via Zoom on June 23 at 4pm CDT.
The following short course option was developed for geology and geophysics students that have not had much exposure to how geoscience is applied in industry. It can be tailored for undergraduate juniors and seniors or graduate students. The agenda can be modified to meet specific needs and time constraints. Contact the presenter to discuss options.

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.
