Cement plays a vital role in maintaining the long term integrity of oil and gas wells by
forming a robust and impermeable barrier and ensuring zonal isolation by restricting the flow
of fluids between different geological zones. In-situ thermal stimulation methods such as
SAGD place the casing cement under extreme stresses due to the rapid temperature
increases that occur during initial steam stimulation. The prevailing mentality in the industry
for many years was that compressive strength alone was a satisfactory predicator of a …
