The Effect of Casing Wear on the Burst Strength of Casing—Part 1: Joint Leakage

Abstract

A theoretical analysis has been performed to determine the effects of wear on the burst strength of casing. Burst failure occurs either by a leakage at the casing joint or by rupturing of the casing wall. Joint leakage and the effect of casing wear on joint leakage are discussed in this paper. Rupturing of the casing wall is treated in a companion paper [1]. The results of the analysis presented in this paper show that, for practical purposes, joint leakage under internal pressure is unaffected by casing wear.
