Recent advances in electronics technology have made it possible to monitor and record real-time annular temperatures in wells during and after primary cementing. These advances have allowed operators to measure the annular temperature during the critical period when cement hydration occurs. Current industry practice is to test critical properties of set cement at bottomhole static temperature (BHST). if the short-term maximum annular temperature is significantly different from the BHST, laboratory tests run on cement at a steady BRST may be inaccurate.
