A general term for injection processes that use special chemical solutions to improve oil recovery, remove formation damage, clean blocked perforations or formation layers, reduce or inhibit corrosion, upgrade crude oil, or address crude oil flow-assurance issues. Injection can be administered continuously, in batches, in injection wells, or at times in production wells.
To assure produced fluid flow and protect your production infrastructure from plugging and corrosion, you need reliable injection lines for your production chemical treatments. Chemical injection lines from Meilong Tube help enhance the efficiency of your production equipment and lines, both downhole and at surface.
Our tubing is characterized with integrity and quality to be specially used in subsea conditions in the industries of oil and gas extraction, geothermal power generation.
