Sequential Backus Averaging: Upscaling well logs to seismic wavelengths

摘要

The measure of geologic knowledge spans a tremendously wide geometric scale. In the vertical dimension alone the range is from microscopic clay particle morphology and pore throat geometry to basinal megatrends many kilometers thick. Of a more limited scope, and inherent to building synthetic seismograms, is the process of relating logging-tool resolution measurements to seismic wavelengths-a tens-of-centimeters to tens-of-meters problem. This upscaling can be achieved by Sequential Backus Averaging.
