Explorer Division Column DPA

Because of publication deadlines I am writing this column in early March, knowing it will be published soon after the Annual Convention in Long Beach.

In February, AAPG was host for the annual Leadership Conference in Tulsa. We invited all affiliated society presidents, committee chairs and others in various leadership positions in AAPG.

Dissemination of information is the prime directive for AAPG -- and by the time you read this column, AAPG will be in the middle of or just past our greatest period of “dissemination” for the year.

Climate modeling in exploration is an idea whose time has come and gone -- and may have come again, according to Eric J. Barron.

Calling the Irvine Ranch Land Reserve (IRLR), “a shining example of our nation’s natural treasures,” National Park Service Director Fran Mainella recently designated 37,000 acres of the IRLR a “National Natural Landmark,” making it the first site in California to receive NNL designation since 1987.

Dan Steward takes pride in doing a good job yet without calling attention to himself. That’s no small achievement. That play was the big reason why Steward was cited as the Explorer of the Year at the recent AAPG Annual Convention in Long Beach, Calif.

This month I want to highlight three items for member attention.

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.

VG Abstract

Hydraulic fracturing has been around for decades. This talk describes some of the first applications of the technology, how it developed over time, and our current understanding of its impacts with some discussion of both water and earthquake hazards.

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.
