AGRICULTUREBENTONITE OCMA
Use
For the production of drilling fluid for horizontal directional drilling. Bentonite OCMA is an all-round drilling product that is particularly suitable for machines with a tractive power from approximately 30 tons upwards. Production of drilling fluid for soil drilling. Production of drilling fluid for oil- and gaswell drilling For optimal efficiency the mixing water of the slurry should have the following properties: Conductivity : ≤ 1000 μS/cm pH : 4.5 – 9
Description
The basis for Bentonite OCMA is an activated sodium bentonite. Bentonite OCMA complies with the OCMA specifications as laid down for oil drilling and is also KIWA certified.
Advantages
- Stabilises the borehole
- Improves the discharge of drilling waste
- Reduces torsion
- Easy to recycle
- Outstanding price - quality ratio
- Certified according to KIWA-ATA, therefore safe for use in drinking water areas.
Specification
Complies with the specifications for bentonite as drawn up by the “Oil Companies Materials Association DFCP-4. Is supplied with KIWA certificate for Toxicological aspects (ATA), which guarantees a 100 % environmentally-friendly product.
