A Review On Environmental and Health Impacts Of Cement

Cement industry is potential anthropogenic source of air pollution. It has estimated that cement production originates about 5% of global manmade CO 2 emissions [13]. The typical gaseous emissions to air from cement production include NOx, SOx, CO, CO 2, H 2 S, VOCs, dioxins, furans and particulate matters [14], [15], [16]. These major

Influence of Cement Return Height on the Wellhead Uplift

In oil and gas production in deep-water high-pressure–high-temperature (HP–HT) wells, wellhead uplift may cause the seal failure of wellbore integrity. Aiming at the oil and gas production stage in deep-water HP–HT wells, we considered the influence of cement sheath cementation and developed a model for calculating the height of wellhead uplifts, and
