Abstract
(EN)
ABSTRACT WELLBORE SERVICING COMPOSITIONS COMPRISING A FLUID LOSS AGENT AND METHODS OF MAKING AND USING SAME A METHOD OF SERVICING A WELLBORE COMPRISING PREPARING A COMPOSITION COMPRISING A CALCIUM ALUMINATE CEMENT, WATER, AND A FLUID LOSS ADDITIVE WHEREIN THE FLUID LOSS ADDITIVE COMPRISES AN ACID GELLING POLYMER, PLACING THE COMPOSITION IN THE WELLBORE, AND ALLOWING THE COMPOSITION TO SET. A METHOD OF SERVICING A WELLBORE COMPRISING PLACING INTO A WELLBORE HAVING A BOTTOM HOLE STATIC TEMPERATURE OF GREATER THAN ABOUT 50 ?F [ABOUT 10?C] AND/OR A PH OF FROM ABOUT 3 TO ABOUT 9 A CEMENT SLURRY COMPRISING A CALCIUM ALUMINATE CEMENT HAVING AN ALUMINUM OXIDE CONTENT OF GREATER THAN ABOUT 60 WT.% BASED ON THE TOTAL WEIGHT OF THE CALCIUM ALUMINATE CEMENT AND AN ACID-GELLING POLYMER WHEREIN THE CEMENT SLURRY HAS A FLUID LOSS AT 10 CC/10 MIN. TO ABOUT 600 CC/30 MIN.
