Abstract
Formation stability surrounding a deviated wellbore penetrating a hydrocarbon reservoir is improved by alternately injecting higher and lower density consolidating materials, the higher density material improving stability in the formation primarily on the low side of the wellbore and the lower density material improving stability in the formation primarily on the high side of the wellbore.
