InvaShield is a Pressure Transmission Control (PTC) system engineered to mitigate pressure penetration into weak and naturally fractured formations, arrest fracture propagation, and enhance wellbore integrity under dynamic drilling conditions.
- Environmentally friendly
- Powdered material for ease of mixing
- Forms aggregates of various lengths eliminating the need to match PSD to pore throat dimensions.
- Does not degrade over time and circulation
- Protects mechanically weak formations, reducing mechanical instability
- Increases fracture formation pressures, lending itself well to increasing LOT/Fracture Gradient etc.
- Prevents induced losses
- Minimises Differential Sticking
