Mud Removal and Spacer Fluids

Effective drilling-fluid removal is a prerequisite for primary cementing success. Mud left in the wellbore prevents effective isolation. This can result in stimulation out of zone, production of unwanted fluids, loss of hydrocarbons to low-pressure zones, sustained casing pressure, underground blowouts, or casing corrosion.

Remove mud with 3D mud displacement simulator

CEMENTICS zonal isolation software

features a 3D-aperture mud displacement simulator that couples in-pipe mixing with annular displacement and accounts for casing rotation, reciprocation, and the azimuthal gradient effect, which is critical in deviated and horizontal wells. The 3D-aperture module incorporates a stiff-string centralization model that simulates angle orientation in the wellbore. WELLCLEAN III pipe and annular mud displacement simulator using a soft-string centralization model is also available.

Ensure proper zonal isolation

The Schlumberger team helps you improve mud displacement through spacer and cement design. MUDPUSH spacer family for cementing and chemical washes provide the required rheology and displacement regime for proper mud removal.
