Mixed Wood Fiber Leak Sealer-Medium-Coarse
Catalog NO.: AIMRSE-CHM-ADD-084 Manufacturer PN: CHM-LKS-WDM
• Effective bridging agent; applicable to different formations; available in fine, medium, and coarse grades according to particle size; rich selection of inert materials; no impact on drilling fluid performance, easy to mix; easily dispersed in mud, biodegradable; non-toxic material.
For permeable formations, acts as a bridging agent and plug to reduce loss; preparing cleaning mud to clean the wellbore.
This plugging agent is a micronized blend of wood-based fibrous materials designed for permeable formations, serving to bridge and seal voids. It is compatible with both water-based and oil-based drilling fluid systems. It is available in three specifications—fine, medium, and coarse—based on particle size, allowing selection of the most suitable grade according to the pore and throat dimensions of permeable formations.
| Type | Leak-off Control Agents |
| Recommended Dosage | For seepage, the dosage is: 30-60 kg/m³; For severe loss, the dosage is: 60-100 kg/m³; Note: When used in oil-based drilling fluid, a dosage exceeding 60 kg/m³ will reduce the demulsification voltage. |
