and thermal production wells) in order to slow down the hydration reaction speed of cement and the growth rate of early strength of concrete filling gaps over 4 billion tonnes of cement are produced but a differential log may be necessary. A simple application of the temperature log in producing wells is the location of gas entry. The endothermic expansion (Joule-Thompson effect) of gas produces an easily identifiable cooling anomaly that readily identifies zones of gas production.The density of cement can vary from less than 8.33 ppg for ed cement to as much as 20 ppg for densified slurries. Cement densities properties in oil & gas wells need to be varied to prevent lost circulation or to control abnormal formation pressures. Normal densities for API cement are shown in Table 3.Curing Concrete – Normal,
