Abstract
Systems and methods for assessing flowability of a multiphase fluid are provided. The method includes agitating a sample of the multiphase fluid contained in a container while controlling an agitation force applied to the sample; pouring the sample, after it has been agitated, into a viscosity cup having an opening at its upper end and an orifice at its lower end and thereby causing the multiphase fluid to flow out of the viscosity cup through the orifice; weighing an amount of the multiphase fluid that has flowed through the orifice and into a receiving vessel over a period of time; and assessing flowability of the multiphase fluid sample using the weight of the multiphase fluid sample in the receiving vessel as a function of time.
