The relatively recent, very large discoveries offshore Brazil have put pre-salt exploration in the South Atlantic back in the foreground. Pre-salt exploration history, however, is far more ancient and marked with some major successes – but also many failures. Here’s a brief overview of this exploration in West Africa until the M’Boundi discovery, which will be described in detail as it brings some lessons that readers can discover for themselves.

Depending on the seismic data quality and either the presence or lack of isolated strong reflectors, identifying horizons can be a trivial exercise or a challenging problem.

At first glance it seems there’s not much overtly new about drilling in the Mississippi Lime – or overtly new about the Mississippi Lime play, either, for that matter – a play that oozes from northern Oklahoma through southern Kansas (and some say, perhaps, to Nebraska).

AAPG is committed to connecting promising original research with much-needed funding and is continually seeking – and finding – new ways to make that potential a reality.

Enter the AMV, or Wave Glider, which is being developed by Liquid Robotics and being considered as the technology to potentially acquire seismic data where other equipment is limited.

Unconventional plays are producing hundreds of wells within relatively small spaces, and all are cranking out more data than any human could possibly track. It’s a fact that has driven the oil and gas industry to search for technology that can intelligently quantify such data and increase the odds of a discovery.

Despite a few lean times – including a stretch when it was derided as the Dead Sea – the GOM always comes roaring back to life to reclaim its position as the shining star of domestic hydrocarbon production.

Seismic data are usually contaminated with noise, which refers to any unwanted features in the data. These unwanted features may actually be somebody else’s signal, such as converted waves in what we think of as “P-wave” data – but more commonly, these unwanted “noise” features provide little or no information about the subsurface, and are referred to as random noise and coherent noise.

It wasn’t so long ago that geologists and geophysicists each labored in their own separate universe, so to speak, with little or no direct interaction. In the mid-to-late 1990s, 3-D seismic grew to prominence as a kind of end-all, be-all in the E&P realm, soon creating a synergy between these professions that is considered to be routine today. (PLEASE USE ‘3-D geologic modeling’ FROM ‘FINAL ARTICLES’ FOR THE ONLINE VERSION.)

A geoscience company some have billed as “Silicon Valley meets the oil patch” has undertaken a study over the Allegheny National Forest in Pennsylvania. Airborne geophysical datasets newly acquired by NEOS GeoSolutions were combined with existing seismic, well, and public domain datasets to better understand the potential of the Marcellus resource play in a roughly 2,500 square-mile area of investigation.

Connectivity in deepwater deposited reservoirs is often times something you don’t know for certainty until you have a well down and flowing. This course is for engineers, geologists and geophysicists who are responsible for economically positive exploration and development of deep-marine reservoirs. It is particularly appropriate for geologist-engineer teams who are responsible for building reservoir development models in these complex systems.

Much of today’s resource play drilling activity focuses on evaluating properties and holding acreage. As resource plays mature, we will want to identify bypassed pay and evaluate the benefits of restimulation. Even with access to such modern data, geology, and hence seismic data and seismic attributes are only one of the components necessary to predict EUR.

Permanent Reservoir Monitoring, also known as Life-of-Field Seismic, using permanently installed seismic cables, has been characterized by a few key marker projects but did not reach mainstream status during its first ten years. However, since the start of its second decade we have witnessed a flurry of new projects and activity so far, both in the Americas (Brazil) and Europe (Norway). Within a time span of about three years, these efforts combined are already dwarfing the efforts of the first 10 years.

The seminar will utilize traverses to examine multiple thrust sheets exposed in Sun River Canyon, the famous Teton Anticline, and an outstanding example of an exposed fractured reservoir along a fault‐propagated fold in Mississippian carbonates as Swift Reservoir. Participants will examine the mechanics of fracturing, folding, and faulting in thrust belt terrains, identify and discuss new ideas regarding the geometry and kinematics of the development of thrust belts, compare seismic interpretation with outcrop examples, and analyze stratigraphic concepts which are essential in the exploration of thrust belt targets.

This structural field course in the Front Ranges of the Canadian Rockies focuses on relating outcrop to seismic expressions of compressive structural styles that are common in fold-and-thrust belts and deepwater passive margins (toe thrust belts) worldwide. Participants will recognize common types of structures in fold-and-thrust belts, apply fault-related folding concepts to interpret these structures, identify petroleum traps and their major structural risk elements, and recognize similarities between styles of trap and reservoir-scale deformation.

Take advantage of this unique opportunity to learn all the aspects related to the understanding and modeling of fractured reservoirs. Attendees will take geologic concepts and use them in reservoir modeling through hands-on sessions devoted to the examination of outcrop, core and log data. They will use that information and a software to create 3D fractured reservoir models. Using actual Teapot Dome (Wyoming, USA) field data from the Tensleep and Niobrara Shale formations and a hands-on approach, the workshop allows the geoscientist to identify fractures and to construct predictive 3D fracture models that can be used to identify productive zones, plan wells and to create fracture porosity and permeability models for reservoir simulation.

Participants will learn a specific and comprehensive methodology for finding and developing conventional and unconventional oil and gas resources associated with lake deposits. The seminar will start with the Quaternary Bonneville basin in Utah, to build familiarity with lacustrine depositional processes. Participants then examine world-famous exposures of organic-rich mudstone, fluvial sandstone, and carbonate microbialite facies in Wyoming.
