Abstract
Integrated interpretation of microseismicity with surface seismic data can provide valuable information about reservoir characteristics, mechanical stratigraphy, induced and pre-existing fracture systems. Although there are numerous integrated studies that focus on unconventional plays, relatively little attention has been given to tight gas environments. Typical interpretation of microseismic data focuses on the spatial and temporal distribution of microseismic events to estimate stimulated reservoir volume and, in some cases, to infer the character and geometry of discrete fracture networks. This thesis describes a methodology for integrated interpretation of 3D seismic data with microseismicity recorded during the open hole stimulation of two horizontal treatment wells of a tight-sand unit deposited in the Hoadley field, a Cretaceous marine barrier-bar complex in Western Canada. I introduce a novel approach, Microseismic Facies Analysis (MFA), to extract additional information from microseismic clusters. The interpreted microseismic facies are then correlated with surface seismic attributes in order to delineate reservoir partitions that are interpreted to reflect lithofacies variations associated with depositional trends.
