Informative Value and Interpretation Reliability of Wide Frequency Range Acoustic Noise Technique in Operating Horizontal Wells

Abstract

This paper is devoted to the problem of informative value and interpretation reliability of wide frequency range acoustic noise technique in operating horizontal wells considering results of laboratory experiments conducted with wellbore mockups. The set of factors affecting the spectrum of acoustic noise recorded in wellbore were experimentally investigated and the necessity for calibrating of noise logging tools to provide results of acoustic measurements in the unified scale is also discussed.
