Abstract
The invention relates to the use of a non-ionic surfactant, with the HLB balance ranging from 10.8 to 16.6, preferably 14, for preparing light foaming cement slurries with a density in the range of 800 and 1300 kg/cubic meter, applicable to primarily grouting the columns for extracting, through the wells, the depleted oil deposits and the oil deposits with high losses of fluid returns into the wells.
