Abstract
The authors review and systematize failure causes in wellbore areas. The present-day methods of sand control are compared with a view to substantiating their efficiency and application ranges. The recommendations on introduction of the most promising techniques are provided. The scope of the discussion encompasses treatment of a well bore area with its reinforcement with different compositions, in particular, the Polyskrep technology using nitrogen. The technology enables minimizing reduction of permeability and increasing rock strength, which enhances rock treatment efficiency.
