Geomechanics and Fracture Analysis

Explorer Emphasis Article

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.

With ICE in one of the most iconic European capitals, the organization committee wanted to shape an ambitious field trip program that would look beyond the British Isles. Against all odds dictated by the unfavorable state of the industry, three field trips accompanied from start to end the success of ICE in London.

Geology is the correct starting point for any geophysical discussion in AAPG. This two-part article starts with the rock, progresses to the wave and concludes with our increased understanding of the rock. If you, dear reader, can stay for both parts, you will gain a basic understanding of how anisotropy in P-P seismic reflection data can add to our understanding of the rocks, specifically the reservoir, at depth.

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.
