Portland cement is the most widely used wellbore cement in the oil and gas industry. Four major crystalline compounds are present in Portland cement: tricalcium silicate (Ca 3 SiO 5 ), dicalcium silicate (Ca 2 SiO 4 ), tricalcium aluminate (Ca 3 Al 2 O 6 ), and tetracalcium aluminoferrite (Ca 4 Al 2 Fe 2 O 10 ). 13 When the compounds of Portland cement are mixed with water, they form hydration products.
