Most drilling-fluid procurement lists are written in brand names — PAC-R, POLY-PLUS, SOLTEX — even when the buyer would accept any product that meets the same specification. Ironstone supplies those specifications: generic products from qualified manufacturers, matched against the brand’s published data and shipped with a certificate of analysis for every batch.
A compatible alternative is not the branded product. It is a generic product manufactured to serve the same function, offered only when its certificate of analysis (COA) can be compared line by line against the published technical data of the product you use today. If the numbers do not support the match, we say so and do not quote it.
The families below have dedicated pages explaining the generic chemistry, what to compare before switching, and how to run a safe trial. The list grows as the catalog grows — if your product is not here, send the name on WhatsApp and we will assess it.
Price is the visible reason: generic additives from qualified manufacturers typically cost meaningfully less than the branded product delivered through a service-company supply chain. The quieter reason is supply control — a second qualified source protects a drilling program when the primary channel is slow, on allocation (supply rationed), or tied to a service contract. Many operations run both: branded product on critical sections, compatible product on everything else.
