The invention relates to an improved method of and composition for the treatment of an incompetent formation penetrated by a wellbore to prevent the movement of sand particles from the formation to the wellbore during recovery of the formation fluids by forming a treating composition of sand, cement, water and xanthan gum in a hydrocarbon carrier oil, injecting the treating composition into the formation under pressure, permitting the cement to set and form a permeable barrier film between the formation and wellbore and recovering fluids from the formation through the formed permeable cement barrier.
