Deliver chemical treatments, even in HPHT and corrosive environments

Chemical injection mandrels are assembled as part of the tubing string when the well is being prepared for chemical injection. Chemicals are used for corrosion prevention as well as to inhibit formation of gas hydrates, scale, asphaltenes, or paraffin in critical equipment in the tubing string.

A stainless steel or MONEL chemical injection capillary tube is attached to the mandrel at surface; the mandrel and injection line are then run to the desired depth with the completion. Manufactured from corrosion-resistant alloys suitable for service in high concentrations of H2S or CO2, mandrels are available for a wide range of tubing sizes. Redundant, field-proven, corrosion-resistant check valves enhance reliability.
