For Fractures, P + S = Maximum Efficiency

In areas where fracture-producing stress fields have been oriented at different azimuths over geologic time, there can be fracture sets of varying intensities and different orientations across a stratigraphic interval.

Unconventionals Will Get Global Showcase at Milan ICE

The fast-approaching AAPG International Conference and Exhibition in Milan will showcase – in association with EMD – a comprehensive unconventional resources program with global scope, ranging in scale from the nanopore to the petroleum system, exploring the latest in applied geoscience and engineering.

Measuring Fractures – Quality and Quantity

As has been emphasized in the three preceding articles of this series, when a shear (S) wave propagates through a rock unit that has aligned vertical fractures, it splits into two S waves – a fast-S (S1) mode and a slow-S (S2) mode.

S-Waves on Crack? Not So Much

This month we continue our series on S waves and factures by taking a look at another laboratory measurement that illustrates an important behavior of S waves that propagate in fractured media.

Turn, Turn, Turn: Rotating for S-Wave Data

This month we expand our insights into the behavior of seismic S waves as they propagate through a fractured interval, with the emphasis placed on laboratory data of real S waves propagating through fractured real-Earth media.

Marcellus Core Areas Differentiated

The Middle Devonian Marcellus Shale has become one doozy of a gas play. In fact, it’s one of the premier shale gas plays of North America in terms of total gas resource, extent, production rates and economic potential, according to AAPG member Bill Zagorski, vice president of geology for the Southpointe, Pa., Marcellus shale division at Range Resources, which pioneered the play.

S Waves Prove Their Worth With Fractures

When a shear (S) wave propagates through a rock unit that has vertical fractures oriented at a reasonably consistent azimuth, it splits into two S waves that propagate with distinct velocities.

How Orogens Could Collapse Forming Sedimentary Basins: The Case of the Betic-Rif Orogen

The Betic hinterland, in the westernmost Mediterranean, constitutes a unique example of a stack of metamorphic units. Using a three-dimensional model for the crustal structure of the Betics-Rif area this talk will address the role of crustal flow simultaneously to upper-crustal low-angle faulting in the origin and evolution of the topography.

VG Abstract By Juan I. Soto

Salt versus Shales in Continental Margins and Orogens

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 By John Suppe

Probing What Makes the Crust Strong (or Weak): Insight from Boreholes, Earthquakes, Active Fault Systems, and Toy Models

For well over a century there have been conflicting indications of the strength of the crust and of faults and what controls them. Much of our ignorance comes quite naturally from the general inaccessibility of the crust to measurement--in contrast with our understanding of the atmosphere, which is much more accessible to observation as well as more rapidly changing. Crustal strength is best understood in deforming sedimentary basins where the petroleum industry has made great contributions, particularly in deforming petroleum basins because of the practical need to predict. In this talk we take a broad look at key issues in crustal strength and deformation and what we can learn from boreholes, earthquakes, active fault systems, and toy models.

DL Abstract By Kurt W. Rudolph

Tectonic Controls on Source Rock Deposition

While there are many habitats that are associated with the deposition of organic-rich marine and lacustrine source rocks, one important pathway is linked to the onset of increased basin subsidence associated with major tectonic events. A key aspect is that this subsidence is spatially variable, with the uplift of basin flanks contemporaneous with the foundering of the basin center, resulting in a steeper basin profile.
