Abstract:
A method comprising preparing a baseline cement slurry comprising a cement, water, and one or more additives, placing a sample of the baseline cement slurry into a sample container having a vertical height, and measuring time of flight of energy through the sample at one or more locations along the vertical height to determine a settling property of the baseline cement slurry. A method comprising providing a settling test apparatus comprising a column having a vertical height and at least one pair of transducers positioned opposite each other with the column there between, placing a cement slurry sample within the column, and measuring time of flight of ultrasonic energy through the sample at one or more locations along the vertical height to determine a settling property of the cement slurry.
