Steamflood and fireflood wells present special challenges when designing a cement slurry In most cases the cement slurry is subjected to relatively low temperature during the cement job and early curing However after the cement sets it must be able to withstand the thermal shock associated with the initiation of steamflooding or firefloodingLiquid Defoamer for cement Slurri Description Liquid Defoamer for cement Slurries is acclaimed for its pure and effective composition We offer this chemical in different grades and specifications to meet the diverse requirements of clients
