A new crosswell electromagnetic (EM) tool, now in field test, provides unique means to remotely sense the resistivity between two wells without having to drill an intermediate well. The wells can be open hole or cased with fiberglass, nonmagnetic chr

This paper first summarizes the theory of providing resistivity images from cross-well electromagnetic (EM) measurements in metal cased holes. Metallic casing significantly attenuates EM signals. As a result, low frequencies are required to acquire u

The directional property of a triaxial induction array makes its response in the borehole environment much more complicated than that of standard induction logging tools. The mathematical model for studying borehole correction should take formation d

Thin-bedded sand-shale sequences frequently exhibit resistivity anisotropy. That is, resistivity measured perpendicular to the bedding (Rv) is significantly higher than the resistivity measured parallel to the bedding (Rh). It is difficult to determi

Resistivity anisotropy in both laminated shale-sand and clean sand formations is well documented. Tools that are sensitive to formation anisotropy are also well documented, and the leading contender for this type of measurement is the transverse indu

An experimental three-coil induction sonde with tilted coils was built to study and then minimize its borehole effect. When such a tool is placed in a conductive borehole and eccentered in a direction perpendicular to the dipole moment of the sensors

In this paper, we present a fast and rigorous inversion method to determine formation resistivity anisotropy, formation bed boundary location and relative dip and azimuth angles from a recently developed triaxial induction tool. This tool is fully tr

Abstract Formation dip can now be estimated in real time with a logging-while-drilling (LWD) tool. A new method allows the Resistivity-At-the-Bit tool to perform the computation as the well is being drilled. The tool calculates the apparent dip direc
