Apparent viscosity

  "id": "MLC-T-OAG-000165",
  "term": "Apparent viscosity",
  "field": "Oil and gas",
  "definition": "A measure of a drilling fluid's resistance to flow under specific shear rate conditions, calculated by dividing the shear stress by the shear rate. For a Newtonian fluid, it is constant, but for non-Newtonian drilling fluids, it varies with shear rate. It is typically reported in centipoise (cP) and is a key parameter for evaluating mud pumpability and hole cleaning efficiency.",
