When a conventional gravel pack completion is not feasible or economical, a Prepack Screen installation is a good option in providing cost effective sand production problem prevention in oil or gas wells. It consists of a base pipe with two concentric V-shaped wire screens which have been gone through internal quality control process of wrap wire specifications and approximately 0.25-in thick interval gravel pack layer placed in between, which is considered as a pre-built gravel pack. The dual jacket design and packing process insures a void free and the gravel pack layer consists of, typically, resin coated and consolidated gravel, but regular re-sieved gravel varieties, will also be available.
