A multicomponent 3D seismic data study from an oil sands field, Alberta, Canada

摘要

Oil sands in the Athabasca region of Alberta are a major hydrocarbon resource. Kelly and Lawton (2012) utilized time-lapse seismic data to study the McMurray formation in the Athabasca region with a detailed geological interpretation of their pre-steam baseline survey. Isaac (1996) processed and interpreted multicomponent 3D seismic data in a heavy oil field in Northeast Alberta, obtaining excellent converted wave volumes. In this project, a multicomponent 3D seismic dataset is used to image and characterize an Athabasca oil sands field. The data provided consists of fully processed PP seismic data, and three-component raw seismic data. The PP data is used for an initial, full volume interpretation including: picking several key reflection horizons, well log ties and post-stack impedance inversion. Joint processing of the PP and PS components is currently underway with promising PS reflectivity being observed.
