Bentonite

We are offering Bentonite - API 13(A)Sec 11 OCMA
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 tr-active 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
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.
• 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.
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.
