Study of Micro Annulus Analysis of Cement Bond Evaluation by using Logging Tools

Abstract

This paper outlines and measures the significance of the cement-bond-log (CBL) tool for cement evaluation programs. And these tool evaluations are often challenged, as is their ability to determine the association between the 􀁆􀁈􀁐􀁈􀁑􀁗􀂶􀁖 compressive strength and the existence of poor cementing bonding. Casing dimensions have an impact on the connection, but cement type and drying conditions have no bearing on them. Significance of certain geometrical parameters on the cement bond log's primary output, or the attenuation of a sonic wave traveling along an interface between cement and casing. For a variety of cement densities, sonic attenuation rates were connected to compressive strengths. There is a discussion of certain experimental logging samples and cementing operation details. Moreover, data connecting attenuation rates to cement densities and compressive strengths are shown.
