Operators need an economical answer to yesterday’s standard tubing conveyed Water Injection Control Systems. They need the ability to change the Water Injection Scheme throughout the life of the well without the major cost of pulling the entire system.


The Terrus injection system provides cost-effective, retrofit wellbore segmentation and injection regulation to improve waterflood sweep efficiency. The system combines regulated injection sleeves with hydraulically actuated zone-isolation packers deployed on production tubing for installation in the existing production casing. Unlike bullhead injection or conventional injection-control devices (ICDs), the Terrus system allows individual zone injection to be adjusted post-installation using wireline- or coiled-tubing-deployed shifting tools. The result is a huge efficiency gain to change the Water Injection Design over the life of the completion without having to pull the completion.
