Geomechanics and Fracture Analysis

Explorer Geophysical Corner

Last month we discussed the importance of accurately describing the geological, geophysical and petrophysical attributes of fractures to optimize fractured reservoir management. Ron Nelson’s 2001, classification of “fracture-dominated” vs. “matrix-dominated” reservoir types helps to recognize the range of porosity and permeability in those producing reservoirs.

Premise: Geological applications of well logs are as broad as geology itself and petroleum geologists can learn from their colleagues in other disciplines.

In the July 2002 'Geophysical Corner' we described a new fracture detection method incorporating a portable laserscan unit to completely image analog outcrops in three dimensions. This month we are going to explore how simple analysis of calibrated analog fracture models can enhance exploration and production in fractured reservoirs.

Workshop
Bogota, Colombia
Wednesday, 17 March Thursday, 18 March 2021, 8:00 a.m.–5:00 p.m.

The AAPG Latin America & Caribbean Region and the Colombian Association of Petroleum Geologists and Geophysicists (ACGGP) invite you join us for GTW Colombia 2021, a specialized workshop bringing leading scientists and industry practitioners to share best practices, exchange ideas and explore opportunities for future collaboration. The 2-day workshop brings together technical experts and industry leaders from Colombia and throughout the Americas to take a multidisciplinary look at future opportunities for exploration and development of Southern Caribbean Frontier Basins.

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.
