SAWDUST
SAWDUST consists of a mix of heat-treated, recycled and kiln-dried white wood with a ratio of up to 50:50. The moisture content is between 5-12%. SAWDUST is hammer-mill processed and screened to ��. SAWDUST is primarily used to combat lost circulation in water-based muds and as an organic absorbent in the event of oil spills.
Application
SAWDUST can be used as a plugging agent during lost circulation events. SAWDUST can be used to solidify waste solids for easier disposal.
Advantages
- Swells, bridges and seals fractures and permeable lost circulation zones
- Can be mixed with other LCM material to formulate LCM pills
- Inert, does not react with drilling fluid additives.
- Is unaffected by addition of salt, acid or brine.
