WebThe temperatures of the wellbore are critical in the design of a cement job. There are basi-cally three different temperatures to consider: the bottomhole circulating temperature (BHCT), the bottomhole static temperature (BHST), and the temperature differential, which is the temperature difference between the top and bottom of cement placement. WebAbstract Accurate prediction of bottom-hole circulating temperatures (BHCT) is important during drilling and completion of a well and is critical to properly design a cement slurry. Downhole temperature is an important factor affecting thickening time of cement, rheological properties, compressive strength development, and set time.
