Organophilic Clay for Drilling Fluids

Organophilic clay is bentonite or montmorillonite that has been organically modified so it can perform in oil-based and solvent-rich systems. In drilling fluids, it is evaluated as an oilfield rheological additive rather than as ordinary water-swelling bentonite. Buyers use this product category when they need viscosity, thixotropy, gel structure and suspension support in non-water continuous drilling fluid systems such as OBM, SBM and invert emulsion mud. The correct grade should still be confirmed by fluid system, base oil and sample testing.

Organophilic clay is used in drilling fluids because it can help build the internal structure needed for rheology control, suspension stability and gel strength in oil-continuous systems. When the grade is matched with the base oil, temperature condition and mixing process, it supports viscosity development and helps keep solids suspended during drilling fluid evaluation. It is not a complete drilling fluid system by itself; it is one additive selected within the wider mud formulation. Buyers should review the TDS and run sample tests before confirming bulk use.

This product page focuses on oilfield drilling systems where organophilic clay is commonly reviewed as a rheology and suspension additive. The supported page scope includes oil-based drilling fluids, oil-based mud, synthetic-based mud and invert emulsion mud. Buyers working with other industrial applications should use the correct future application page instead of this oilfield page. For drilling fluid selection, share the fluid type, base oil, operating temperature, density target and rheology goal before requesting a grade recommendation or sample. This keeps the recommendation process focused.

Start with the drilling fluid system, base oil, temperature condition, target viscosity or rheology profile, dispersion method and document requirements. Then compare the approved OD-series grade paths and request the current TDS before testing. If the application is unclear, do not choose by model name alone. Send your drilling system, base oil, target performance, estimated quantity and required documents to the technical team so they can route you toward a suitable sample, document request or quotation path. This reduces selection risk.

Yes. Buyers can request the current TDS for technical review, formulation evaluation, internal approval and supplier comparison. The TDS request path is useful before sample testing because it helps technical and procurement teams understand the product category, application focus and document status. SDS/MSDS and COA support can also be requested through the document section when safety review, compliance review or batch-level confirmation is needed before purchasing. For faster response, include your company, country, target system and expected quantity. This speeds document handling.

Samples are available for buyer evaluation when the request includes enough technical context. To improve recommendation quality, share the drilling fluid system, base oil, temperature condition, target rheology, expected quantity, destination country and required documents. The team can then help confirm whether the request should start with TDS review, sample testing, quotation support or a product recommendation. Final product selection should be confirmed through document review and actual formulation testing before any large order or long-term supply decision. This reduces procurement risk.
