METHOD, DOWNHOLE SYSTEM AND FLUID LADEN WITH PARTICLES TO FORM A BARRIER OR RESTRICTION IN A WELLBORE FLOW CHANNEL

摘要

The invention relates to a method, a downhole system and a fluid laden with particles to form a barrier or restriction in a flow channel outside a liner extending in a subsurface wellbore in an earth formation. The fluid laden with particles is expelled through a first opening in the flow channel outside the liner and a second fluid is expelled through a second opening to affect the position of the barrier or restriction and to prevent the particles of the first fluid from blocking the first opening.
