High temperature fluid loss agent XBA-203L
Introduction
XBA-203L is a high temperature fluid loss agent.
XBA-203L’s applicable temperature is 60~150℃(BHCT).
XBA-203L is resistant to salt and applicable to saturated brine.
XBA-203L has a retarding effect and is suitable for high temperature and deep well cementing.
XBA-203L slurry system is stable and has good compatibility.
XBA-203L is liquid and only can be used through wet mixing.
XBA-203L’s dosage need to be adjusted according to temperature, salinity and cementing requirements.
