CA-NUTPLUG Lost Circulation Material

PRODUCT DESCRIPTION

CA-NUTPLUG is grounded walnut shell, a lost circulation material that can be used in both oil‐base and water‐base systems. It is available in three sizes, fine, medium and coarse. Walnut shell can be mixed in combination with other LCM.

​

APPLICATION

As a lost circulation material CA-NUTPLUG is especially adapted for plugging induced fractures. Walnut shells are also used to reduce torque and drag of drill pipe and drill collars, especially in high angle holes. Walnut shells are used as a sweep to scour the well bore and tools when sticking clay is a problem.

ADVANTAGES

• Is compatible with other lost circulation materials.

• Seal fractures and permeable zones to prevent loss of fluid.

• High compressive strength/non‐absorbing.

RECOMMENDED TREATMENT

Typical treating levels for preventative measures are from 2 to 5 lb/bbl (5.7 to 14.2 kg/m3), and for more severe losses use 5 to 25 lb/bbl (14.2 to 71.3 kg/m3). CA-NUTPLUG has a high compressive strength, and can be used, if desired, as a lubricant.
