Lost Circulation & Wellbore Strengthening Materials
Bridging, while-drilling, composite and acid-soluble materials for loss control, wellbore strengthening and improved pressure-bearing capacity.
Local bridging at the fracture opening
- Mast & hoisting system
- Drillstring
- Mud with bridging material
- Fracture-mouth bridge
- Near-well fracture
Flow: Annular return; some particle-bearing fluid enters the fracture and bridges near its mouth
Local open-hole section; the bridge restricts the fracture entrance, not the main wellbore.
Local section · depth compressed; diameters and interaction areas enlarged · not to scale
