Seismic inversion at Pike's Peak, Saskatchewan

Ian Watson and Larry Lines

ABSTRACT

An acoustic impedance inversion of a 2-D seismic swath line from the Pikes Peak Heavy Oil field in Saskatchewan, Canada is presented in this report. The results indicate a low impedance zone where steam has been injected into the reservoir formation, the Waseca member of the Mannville Group. The very high impedance Devonian carbonates are also shown. One well located on the 2-D line was used to constrain the interpretation and impedance values for the model-based inversion. Several modules from the inversion software package, Jason Geoscience Workbench, are described as they pertain to the inversion process.
