Centralizing devices to complement acoustic logging tools

Abstract

Abstract One of the cornerstones to high-precision acoustic logging equipment is high reliability and maneuverability of tools in a sophisticated well. The paper outlines the requirements for centralizing devices (CD), experimental and theoretical rationale for different configurations, and the need for appropriate calculations. The outputs involve a series of updated centralizing devices, the classification of centralizing devices and a crossplot that all allow for an optimal centralizing configuration to be selected depending on the equipment available and a well examined.
