Investors | Careers ACCELUS™ BALL-SHIFT FRAC SLEEVES Accelus ball-shift sleeves are used to stimulate individual stages of multistage completions at high frac rates in a continuous pumping completion. The sleeves are placed in the completion string according to the completion design. After a ball pumped down the surface seals on the inner sleeve ball seat, pressure buildup shifts the inner sleeve to open the frac ports for stimulating the formation.

Investors | Careers PROBLEM 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. SOLUTION 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. WE WOULD LOVE TO HEAR FROM YOU.
