An attempt was made to devise a simple method for accurately estimating rock matrix acoustic travel time for heterogeneous carbonate samples. Compressional wave travel time was measured for each of several hundred madison carbonate samples from the Williston Basin and is related to the corresponding sample porosity and bulk density. Least-squares equations for the linear plots of compressional wave travel time versus porosity and bulk density yield rock matrix travel times at zero porosity and bulk density equal to rock matrix density. However, the data are scattered enough for the authors to conclude that these relationships do not provide a reliable method for estimating rock matrix acoustic travel times.
