WebApr 11, 2024 · Especially, at downhole conditions, the temperature gradient is assumed to be 30 °C/km, which can be varied with the location (Nasvi et al., 2012a). The well cement which is used in the CO 2 sequestration process should have a greater stability and a crack-free surface to carry out a successful CO 2 sequestration process under elevated ... WebFarther up the hole, the correct temperature is calculated by assuming a certain temperature gradient. The BHT lies between the bottomhole circulating temperature (BHCT) and the bottomhole static temperature (BHST). Alternate Form: BHT 2. n.
