INTRODUCTION Induction tools are always used to measure formation resistivity by using a low-frequency alternating current to induce an eddy current in the formation. Modern induction tools acquire both...

... the data measured by an array induction tool in high angle wells. We start from the very original conductivity logs measured by a multi-spacing, multi-frequency tool. First, skin effect correction and borehole effect correction are applied to the data. Then, a set of filters were designed to acquire...

... Symposium held in Oklahoma City, Oklahoma, USA, June 17-21, 2017. ABSTRACT The tensor-type apparent conductivity acquired by triaxial induction tools enables the determination of both resistivity and resistivity anisotropy of a reservoir. The most popular anisotropic model for triaxial data interpretation...

Figure 16 above shows the acquired data. LWD processed results (blue...

... Abstract The concept of triaxial induction measurements can be traced back to 1960s. The first commercial triaxial induction tool has been in service for more than a decade. The tensor type of measurements acquired by the triaxial induction tool enables extracting not only the resistivity...

... Abstract Triaxial induction tools were initially designed to measure anisotropic resistivity and the dip of formations. Recent application of the high-resolution zero-D dip provides excellent structural dip information by involving mathematical inversions of the data. A new application using...
