“…Various techniques have been proposed to model this problem. These include brute-force numerical methods such as finite-differences (FD) [7]- [10] and finite elements (FE) [11]- [13], and pseudoanalytical approaches [4], [5], [14]- [19]. The former can handle arbitrarily complex Earth formations but suffer from high computational costs.…”

Abstract-We develop a pseudoanalytical method for the analysis of directional resistivity well-logging tools consisting of multiple tilted-coil antennas in cylindrically-layered Earth formations which have anisotropic conductivities and where each layer may be eccentric to the others (multieccentric formations). The cylindrically-layered, anisotropic, and multieccentric scenarios considered here are often encountered in deviated/horizontal drilling for hydrocarbon exploration, where the logging tool may be eccentric to the borehole due to mechanical vibrations and/or gravitational pull, and where eccentric invaded zones (of mud filtrate into the formation) may also arise because of gravitational pull on the mud filtrate.

“…A three-dimensional (3-D) finite volume (FV) algorithm has been developed and successfully applied to simulate electromagnetic (EM) well-logging tool response in high-loss geophysical formations [11]- [14]. In low-loss media, however, its application implies increasing the computational domain.…”

“…Hue and Teixeira (2007) have used the numerical modematching method to evaluate the induction response of tilted loop antennas in cylindrically stratified formations with uniaxial anisotropy. For solving similar problems, Novo et al (2007) have developed a new FV technique based on a vector-scalar (A, u) potential formulation.…”

Near-surface applied electromagnetic geophysics is experiencing an explosive period of growth with many innovative techniques and applications presently emergent and others certain to be forthcoming. An attempt is made here to bring together and describe some of the most notable advances. This is a difficult task since papers describing electromagnetic induction methods are widely dispersed throughout the scientific literature. The traditional topics discussed herein include modeling, inversion, heterogeneity, anisotropy, target recognition, logging, and airborne electromagnetics (EM). Several new or emerging techniques are introduced including landmine detection, biogeophysics, interferometry, shallow-water electromagnetics, radiomagnetotellurics, and airborne unexploded ordnance (UXO) discrimination. Representative case histories that illustrate the range of exciting new geoscience that has been enabled by the developing techniques are presented from important application areas such as hydrogeology, contamination, UXO and landmines, soils and agriculture, archeology, and hazards and climate.
