Mechanical surging is applied to the well to physically remove buildup from the well screen and to force the acid out into the gravel pack and/or aquifer to clean the voids between particles.
This dispersing allows the mechanical surging action to flush the mineral and bacterial material out of the screen, gravel pack, and aquifer, followed by its removal from the well.
in diameter) encased by a designed gravel pack
usually varying in diameter between 18 and 48 in.
Expros DST/TCP Global Business Development Manager, Kerry Daly added: The 30,000 PSI TCP guns and associated equipment were specifically designed for the deep water environment, where operators typically frac or gravel pack
wells after perforating and require the most AOF possible.

During pumping, oil is often filtered through gravel packs
to remove particulates.
