Inversion of Travel Time for Velocity Using Multi-Spacing Sonic Tools
Spatial resolution of sonic logs is greatly affected by the minimum spacing between receivers. Improvements can be made, however, when the spatial sampling of the formation is less than the minimum spacing. This paper proposes a recursive least squares inversion of travel times based on the Kalma...
