A numerical simulation study has been made of borehole sonic measurements that examined shoulder-bed, anisotropy, and mud-filtrate invasion effects on frequency-dispersion curves of flexural and Stoneley waves. Numerical simulations were considered f

This paper describes the implementation and successful validation of a new staggered-grid, finite-difference algorithm for the numerical simulation of frequency-domain electromagnetic borehole measurements. The algorithm is based on a coupled scalar-

Presence of near-wellbore damage, resulting from drilling and mud-filtrate invasion, can substantially affect sonic and resistivity borehole logging measurements. Therefore, unbiased log interpretation must account for presence of invasion in order t

We develop a novel adaptive inversion technique: Data-adaptive Spatial Resolution Inversion (DSRI) method. DSRI eliminates the need to select parameterization prior to inversion. Instead, one performs a hierarchical search for the correct parameteriz

The application of time domain reflectometry (TDR) to determine soil water content via soil dielectric measurements has been widely investigated [Topp et al., 1980; Topp et al., 1982, and references therein]. These investigations have shown TDR to be
