MF-Foam B
MF-Foam B
Two-component polyurethane foaming system for rapid sealing of lost circulation zones and borehole stabilization. Formerly HPM FOAM B.
MF-Foam B is one component of a two-liquid foaming system designed to produce a rigid polyurethane foam. It is used together with MF-Foam A for fast sealing of lost circulation zones, cavities and unstable formations.
Advantages
- Rapid sealing of lost circulation zones
- Effective where conventional LCMs may pass through
- Helps reduce lost circulation and caving problems
- Supports borehole stability until completion
- Works effectively in small quantities
Applications
MF-Foam B is used with MF-Foam A for pre-collar sealing as an alternative to cement. It can also be used for sealing cavities, thief zones and problematic formations.
Typical Properties
| Property | Value |
|---|---|
| Appearance | Light to dark brown liquid |
| Odor | Mild |
| Specific Gravity | 1.2 |
Recommended Treatment
Mix MF-Foam A and MF-Foam B at a 1:1 ratio by volume.
Stir for 20–40 seconds until a cream color develops, then immediately pour into the pre-collar annulus or thief zone.
The rigid polyurethane foam will develop and set within approximately 4 minutes.
