Cement Bond Strength Measurements

Cement is an important component to ensure safe and economic sustainable operations of wells. To optimize the performance of cement in a well, and to achieve an adequate level of well integrity, experimental testing of cement under realistic and relevant conditions is vital. This paper reviews three different types of cement bond strengths relevant for the petroleum industry and gives an evaluation of the methodologies used to study these bond strengths. Although the term “Bond strength” should at first be assessed and discussed as an easy-to-understand parameter, the review shows that it is important to understand the fundamental differences between the three-bond strengths. In terms of how they are measured, and in terms of what the information can be used for.
