A customer with a steam assisted gravity drainage (SAGD) well pair in the Alberta, Canada oil sands was experiencing poor steam chamber conformance along the length of the producer well, resulting in localized hot spots and production restrictions. Looking for ways to optimize performance, the customer contacted Baker Hughes, a GE company (BHGE) for a solution.

After conducting field and well analyses, the BHGE team proposed that the customer install EQUALIZER HELIX™ passive inflow and injection control devices (ICDs) in the underperforming SAGD producer well. The ICDs feature a helical geometry that creates a pressure drop based on friction. This, combined with the ICD’s robust construction, helps to equalize the injection profile and improve long-term production.

The completion was designed around temperature, pressure, geological, and well proximity data, and used high-temperature REBarrier™ swell packers to compartmentalize flow in the lateral. The design was optimized to counteract the specific production limiting issues in the producer well to improve wellbore conformance, and to make production more efficient.
