Deformation Band Analysis, Hillsdale Canyon, Utah
Geological Sciences, California State University Bakersfield, Bakersfield, CA, USA
Deformation band shear zones can alter the migration path of hydrocarbons through permeable sandstone reservoirs. Understanding the petrophysical qualities of faulted zones is significant in reservoir modeling and characterization. This study aims to characterize the microstructures and properties of deformation bands in Hillsdale Canyon, Utah. To achieve this, observations of deformation bands will be used to construct a map of the structures as related to local faulting. Characteristics including size, spacing and orientation will be measured and categorized. Samples will be collected for analysis through petrographic and scanning electron microscopy to determine porosity differences between the deformation bands and the surrounding host rock. This information will be used to deduce any relationships between deformation band development and proximity to faulting as well as with variations in lithology. This information can be utilized by petroleum geologists to predict subsurface fluid migration through fractured reservoirs.
