Organoclay for Oil-Based Mud

In oil-based mud, organoclay is an organically modified clay that builds internal structure across the oil-continuous phase. That structure raises viscosity and yield point, develops gel strength, and helps suspend barite and drilled cuttings so they are carried during circulation and held at static. It performs as one rheology additive inside the wider OBM formulation, working alongside emulsifiers, wetting agents and weighting material. Performance depends on matching the grade to the base oil, temperature condition and mixing energy, so the grade and loading should be confirmed by TDS review and sample testing before bulk use.

It depends on the base oil, density target, temperature and the rheology profile you need. For general oil-based mud viscosity and suspension, buyers often begin with the OBM viscosifier path around OD-20; dispersion-sensitive systems may review OD-28 or OD-E29, and high-temperature or HPHT wells point toward OD-29. Rather than choosing by model name alone, share your base oil, mud weight, temperature and target yield point so the technical team can route you to a suitable OD-series grade. Confirm the final choice with the current TDS and a controlled sample test in your own OBM.

Organoclay is the additive category most commonly used as the primary viscosifier and suspension agent in oil-based mud, so the two are closely related but not identical. "OBM viscosifier" describes the function inside the mud system, while organoclay (organophilic clay) describes the modified-clay material that delivers that function. On this page the two are discussed together because organoclay is selected specifically to build OBM rheology and gel structure. The correct grade for your viscosifier role should still be confirmed by base oil compatibility, TDS review and sample testing.

Loading depends on the base oil, mud weight, temperature and the target viscosity and yield point, so a single fixed dosage is not published here. Specific values belong in the current TDS and should be confirmed through formulation testing in your own OBM rather than copied from a generic figure. To get a suitable starting point, send your base oil, mud density, temperature condition and rheology target, then request the TDS. The team can help you plan a sample test that establishes the correct loading for your oil-based mud before any large order.

Before purchasing organoclay for oil-based mud, request the current TDS for technical and formulation review, the SDS/MSDS for safety, handling and compliance review, and a COA where available when batch-level quality confirmation is required. These documents help technical and procurement teams evaluate the product category, application focus and document status before sample testing. For faster handling, include your company, destination country, OBM system details and expected quantity so the team can route the correct document and sample path for your evaluation.

Yes. Samples are available for buyer evaluation when the request includes enough technical context. Share your oil-based mud system, base oil, mud weight, temperature condition, target rheology, expected quantity, destination country and required documents. The team can then confirm whether to start with TDS review, a sample test, quotation support or a product recommendation. Final grade selection should be confirmed through document review and actual formulation testing before any large order or long-term supply decision, which reduces procurement and performance risk.
