Every oil well is drilled with a heavy mud made dense by barite, and India mines a third of it.

Where it comes from

Chart: Map of where it comes from

Muds are blended from barite, about 70% of which goes into drilling, plus bentonite, starch and polymers; frack fluids use polyacrylamide or guar.

Three things to know
  1. SLB paid $7.8 billion for ChampionX in July 2025 to own production chemicals, which are dosed for a well's whole life.
  2. About 70% of barite goes into drilling mud, and India produced about 3.0 Mt of it in 2025.
  3. Drilling fluids are the largest slice, about 35% of the market, worth roughly $9.0 billion.
The journey
  1. 1 Raw materialsBarite, bentonite, guar, base oils, acrylonitrile
  2. 2 Active ingredientsPolymers, surfactants, inhibitors, amines
  3. 3 Basin blendingField-specific packages mixed near oilfields
  4. 4 Downhole useDrilling mud, fracking fluid, production inhibitors
  5. 5 Oil and gasWells drilled, stimulated and kept flowing
