... corrections are critical to proper interpretation of the dataset. However, the accuracy of the terrain correction is most often a function of the res- olution of the available digital elevation model (DEM). As a result, higher and higher resolution DEMs are acquired during gravity gradient surveys. While...

... Approximation (SCA) and Differential Effective Medium (DEM) theory. Such an approach honors the rock microstruc- ture, i.e., a continuity of both the solid and fluid phases in the rock; and also makes realistic estimates that fall within the Hashin-Shtrikman (HS) bounds for elastic moduli. We have modeled two...

... theoretical effective medium models. Differential effective medium (DEM) model is one such theoretical model which accounts for changes in elastic moduli due to changing pore geometries and facilitates inclusion of two or more than two pore shapes. If bulk porosity and water-saturated P-wave velocities...
