Key words:lost circulation, well cementing, lightweight aerated cement slurry, lightweight aerated abrasive buffer.

The paper provides details of compositions and technologies designed to prevent lost circulation in complex geological conditions of East Siberian fields.
Lightweight aerated cement slurry which is compatible with lightweight aerated abrasive buffer is characterized by elasticity, carrying ability, sedimentation and suffusion resistance, controlled density that is modified through the variation of intensity and duration of hydrodynamic activation.
