AAPG functions because of you, the members, and there are many different ways for you to get involved in your organization. Some choose to start in their local affiliated society, working on committees and holding offices within them. Others get involved through leadership and organizing events within the sections and regions. These are the grassroots of our membership, and AAPG leadership is working to strengthen these roots.

The Unconventional Resources Technology Conference was held this year in Denver, Colo., and once again, it did not disappoint. It was packed with technical presentations and exhibits and it continued to push boundaries and remain as the premier industry event focused on the latest science and technology in exploration and development of unconventional resources.

Collaboration. Scott Singleton, geophysical technology adviser at Independence Resources Management in Houston, wants to underscore that one word. He believes that if there’s a single ingredient to success in unconventional fields – and the one concept from which those in unconventionals have unfortunately moved away – it’s that geologists, geophysicists and engineers have to work together for the benefit of everyone.

Each year, AAPG's Petroleum Structure and Geomechanics Division recognizes what the membership considers the best recent and seminal publications in the field. This year's Best Seminal Publication award recognizes Tod Harding and Jim Lowell for their 1979 paper, 'Structural styles, their plate-tectonic habitats, and hydrocarbon traps in petroleum provinces,” published in the AAPG Bulletin 63. Division Chair Bob Krantz praised the work as 'truly foundational.'

Mark G. Rowan, one of two recipients of this year’s Robert R. Berg Outstanding Research Award, was more than just a little bit surprised about his selection – as much for being considered as for winning. Rowan received the honor for “his outstanding contributions to research on salt tectonics, fold-thrust belts, passive margins, diapirs and salt sheets, salt-sediment interaction and cross-section restoration.”

The continent of Africa has beguiled geologists for centuries. Its varied and beautiful landforms and geological features, its mineral and energy resources, its cultural heritage – it’s the birthplace of our species – all combine to form a rich experience of sights and sounds, aromas and flavors. Once you’ve been to Africa, you want to go back. And that’s why, after 10 years, we’re heading back to Africa next month – back to Cape Town, for the 2018 AAPG International Conference and Exhibition.

If a taint exists on the use of geophysics to evaluate fracturing operations, it is this: ‘T ain’t easy. In fact it’s downright difficult, said Arash Dahi Taleghani, associate professor of petroleum and natural gas engineering in the Department of Energy and Mineral Engineering at Penn State University, whose research areas include studying how natural fractures can affect hydraulic-fracture geometry and using seismic for modeling natural fractures and post-treatment fracture analysis.

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.
