RiSwell XLCM-1
Extreme Swellable LCM
JUMP TO
GENERAL DESCRIPTION
Weak or fractured formations can result in fluid losses. RiSwell XLCM-1 is a cost effective and low complexity solution designed to isolate formation damage and mitigate extremely high-loss zones. This enables zonal shutoff with a single, simple treatment.
RiSwell XLCM-1 utilizes field-proven swelling elastomer technology, combined with activated fiber, to deliver a high-pressure seal.
HOW IT WORKS
RiSwell XLCM-1 integrates super absorbent elastomers with an osmotic swelling mechanism. The swellable elastomeric rubber and activated fibers work together to form a high-integrity sealing matrix. Upon contact with drilling fluid, RiSwell XLCM-1 particles expand and interlock, creating a three-dimensional network that conforms to fractures and voids. This results in a robust, reliable barrier capable of withstanding differential pressures up to 10,000 psi and enduring repeated pressure cycling over the long term.

APPLICATIONS & BENEFITS
APPLICATIONS
APPLICATIONS & BENEFITSRiSwell XLCM-1 particulates are batch-mixed at surface and pumped downhole using standard cementing or mixing equipment. The design and volume of the particulate material are tailored to the specific size of the void space within the target zone.
Its simplicity and versatility make RiSwell XLCM-1 suitable for a wide range of isolation challenges, including:
-
Water Control
-
Sustained Annular Pressure
-
Cementing and Casing Integrity Solutions
-
Fluid Loss Control in Extreme Downhole Enviroments
