Mud Removal
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.
Increase cementing success
WELLCLEAN II engineering solution comprises innovative products and tools. Improve your cementing jobs at the least expense. Tools include CemCADE cementing design and evaluation software and the WELLCLEAN II simulator.
Improve flow around the annulus
Since fluids in the annulus tend to flow more freely on the wider side, casing centralization is critical. The CemCADE centralization module assists the engineer in determining the proper centralization for effective mud removal.
Remove mud completely
Mud removal can be achieved in laminar or turbulent flow regimes. The WELLCLEAN II simulator aids the Schlumberger team in making the right choice. The simulator indicates cement coverage, the risk of a mud film or channel and the turbulent contact time.
Ensure proper zonal isolation
The team helps you improve mud displacement through spacer and cement design. MUDPUSH II spacers and chemical washes provide the required rheology and displacement regime for proper mud removal.
