Drilling and Cementing Technology

Effects of Long-Term Exposure to Ultrahigh Temperature on the Mechanical Parameters of Cement

Long-term cement-sheath mechanical durability is critical to maintaining zonal isolation for the life of a well. Wells subjected to cyclic steam stimulation (CSS) undergo extreme temperature changes that cause substantial stresses on the cement sheath. Analysis models that are useful in predicting the failure potential of a cement sheath require input of cement mechanical parame-ters. The full-length paper presents a test methodology for measuring the mechanical parameters of five cement formulations after exposure to 645°F.
