Oil Well Cement Dispersant
Oil well cement dispersant XBA-303
Introduction
XBA-303 has two types：XBA-303L (liquid ) and XBA-303S (solid);
XBA-303 could significantly reduce consistency，improve liquidity and rheological behavior of cement slurry.
XBA-303 has wide range of applicable temperature to meet the needs of high, medium and low temperature cementing requirements;
XBA-303 is resistant to salt and applicable to saturated brine.
XBA-303L only can be used through wet mixing.
XBA-303S could be used through wet or dry mixing.
XBA-303’s dosage need to be adjusted according to the performance requirements of cement slurry.
