Abstract: A method of measuring the viscosity of cement slurry used for a primary cementing of an oil or gas well includes pumping the cement slurry along a conduit to a cementing location, measuring a first pressure loss along a first, horizontal portion of the conduit and a second pressure loss along a second, vertical portion of the conduit, and calculating a viscosity of the cement slurry based at least in part on the first and second pressure losses and a flow rate of the cement slurry.
