Abstract
Natural fractures are pervasive in most rocks, but their role in oil and gas exploration and production is often vastly underappreciated. Fractures can be key factors in understanding drilling, stimulation and production experience. Unfortunately, industry’s recent focus on engineering over geoscience has tended to minimize the contribution of fractures. One of the reasons for this is that it is difficult to quantify their distribution, orientations, types and mechanical properties for incorporation into engineering models. That said, some relatively recent industry concerns including induced seismicity, frac hits and casing shear are causing us to re-evaluate our estimation of the importance of natural fractures.
The purpose of this talk to introduce the concept of fracture tomographic imaging (TFI) using microseismic. Pioneered by Global Geophysical in the early 2010s, the methodology captures far more information from microseismic than what we normally focus on during stimulation mapping. TFI’s can reveal not only near-wellbore natural fractures, but also extensive fracture networks capable of providing fluid connectivity between wells or from wells to faults. Fracture network information can be incorporated into reservoir models, and TFI’s can even be used for stress inversion.
This talk will include a combination of critically stress fault and TFI theory as well as a variety of examples of TFI application. Emphasis will be on the importance of TFIs to geomechanical understanding.
Biography
Amy Fox earned an undergraduate degree in Geology from the University of New Hampshire and a Doctorate in Geophysics from Stanford University, specializing in geomechanics. She has been involved in geomechanical consulting for the oil and gas industry since 1998, starting her career with GeoMechanics International (GMI) in Palo Alto, California. She moved to Calgary in 2011, and in 2015 she co-founded Enlighten Geoscience Ltd. where she addresses a variety of geomechanics issues for a wide range of clients both in Canada and globally. Amy enjoys spreading the geomechanics gospel through publishing articles, giving talks, teaching courses and volunteering.
