Case Study Tullow Ghana Improves Deepwater Zonal Isolation
CemFIT Shield cement system eliminates mud channeling in highly permeable sandstone reservoirs.
Remove drilling fluids prior to cementing operations and achieve long-term zonal isolation
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.
The Schlumberger team helps you improve mud displacement through spacer and cement design. MUDPUSH cementing spacer family provide the required rheology and displacement regime for proper mud removal.
