  • Removing Mechanical Skin in Heavy Oil Wells

    CHOP implies that sand enters the wellbore with the oil. This leads to nonconventional production enhancement mechanisms. First, if sand is permitted to move, intrinsic resistance to fluid flow in a porous medium is reduced. Second, as sand is produced, a region of enhanced permeability is propagated outward from the production well;
