The Borais Surge Disk Device (DSD) is an innovative sub designed to enhance efficiency and safety in well completion and workover operations. Positioned beneath the production packer at the base of a single completion string, the DSD serves as a blanking plug to set the packer, test tubing integrity, and unload the well automatically—either underbalanced or overbalanced—without relying on risky wireline interventions. Developed by Borais Petroleum Investment Co., this tool streamlines critical processes, boosts production, and reduces operational costs, making it a valuable asset for oil and gas operators seeking reliable and economical solutions.
