Completion Operations - Gravel Packing Procedures

Perforation prepacking refers to the methods that can be used to pack the perforation tunnels with gravel prior to filling the screen/casing annulus. The main objective of prepacking is to maximise the quantity of high permeability gravel placed in the perforation tunnels (or in cavities behind the casing) which is one of the key factors controlling the productivity of an IGP completion. Field experience indicates that in many cases standard gravel packing procedures do not allow proper packing of the perforations.
