Interpretive Summary:

Technical Abstract: One of the primary barriers to prevent wellbore leakage is cementing. A leaking wellbore can contaminate groundwater and pose a safety challenge. One of the wellbore leakage paths is between the cement and steel casing, known as a microannulus, occurs due to de-bonding. In this work, the objective is to determine the tensile bonding strength of cement to steel under different applied strain rates. A cement mixture consisting of class H Portland cement, distilled water, and D-Air 5000 was cured on a metal base for two days under STP conditions. The laboratory investigation consisted of 34 samples that were tested at a strain rate of 0.1, 1.0, and 10 mm/min. The results showed that the maximum tensile strength differs for the three strain rates. The strain rate of 0.1 mm/min showed the lowest tensile strength while the 1.0 mm/min showed the highest.
