Mapping the sand/shale distribution in the Blackfoot field - a geostatistical approach

Todor Todorov, Grace Y.C. Yang, and Robert R. Stewart


In oil exploration, our data usually falls into two categories: sparse but accurate well logs and dense but inexact seismic traces. A geostatistical approach allows us to merge the data sets and create detailed geological images.

In the current case, a Vp/Vs data set from seismic isochrons and fractional percentage shale values, estimated from gamma ray logs, was used to generate a fractional percentage shale distribution map of Mississippian to the top of a glauconite sand channel event in Blackfoot area, Alberta.
