Development of a resource play such as the Duvernay Formation is subject to intrinsic risks. These may include the risk of incurring additional costs due to induced seismicity, or risks associated with lithologic heterogeneity or unexpected thermal maturity (e.g., dry gas vs. condensate). Proximity to basement-rooted faults is a known risk indicator for induced seismicity, but it may also influence the depositional environment and/or the past or present thermal state of a reservoir, especially if the basinal fluid circulation patterns are fault-controlled. In the case of the Duvernay Formation, off-reef depositional systems include contourite deposition, turbidity/mass flow and insitu biological carbonate precipitation. Deep-seated strikeslip faults may also have played a role in these systems. Here we present a study consisting of 3-D/3-C seismic data, and co-located microseismic surveys in an active hydrocarbon development area. Joint interpretation is enabled by combining microseismic data with seismic-reflection data and displaying the data in depth. A geological picture is constructed by visualizing microseismic hypocenters. This type of visualization can be used to determine best practices for the future location and design of horizontal treatment wells.
