Geological interpretations from seismic data at Pikes Peak, Saskatchewan

Ian A. Watson and Laurence R. Lines


Coincident vertical array and multi-component 2D seismic lines are interpreted and integrated with geological data to further understand the geology of the Pikes Peak heavy-oil field in Saskatchewan. Using vertical array seismic data, a salt isochron method predicts the reservoir trap configuration and identifies the risk of bottom water in the Waseca reservoir. An interpretation of multi-component data over the reservoir interval allows for the calculation of the compressional to shear wave velocity (V P /V S ) ratio. This ratio is compared with the percentage of sand in the reservoir interval from wells adjacent to the seismic line. Filtering for noise and the effects of steam and heat in the reservoir, the ability to predict the percent of clean sand in the reservoir has an 80% correlation coefficient.
