Flow Potential Units Determination & Successful Isolation Utilizing the New Crosswell Spectral Acoustic Analysis

Abstract

This presentation will demonstrate the evolved spectral acoustics methods to analyze the well barriers efficiency with characterization of the contributing zones: local pressured zone, annular pressure traps versus extended one and flow potential formations
The diagnostics are performed riglessly prior Plug and Abandonment (PnA) or workover, including cases when the tubing is still in hole. The main focus is set to passive acoustics and spectral analysis of data acquired at different logging regimes. Unlike traditional noise logging, where the interpretation leads to the simple conclusions leak/no leak, spectral passive acoustics targets classification of the type of flow: channeling, microannulus, contributing zones or cement isolation quality with the help of other methods normally utilized during PnA: ultrasound and cement bond logging, lithology, open hole logs and drilling reports. The interpretation is extended to correlation analysis of spectral acoustic data obtained in nearby wells. The cross-well analysis enables tuning the interpretation of every single survey and provides confident results even if other data is missing.
