  • Patent number: 11326417
    Abstract: Some aspects of what is described here relate to analyzing a well cement slurry. In some aspects, a well cement slurry is mixed in a mixer under a plurality of conditions. The plurality of conditions correspond to a plurality of distinct Reynolds number values for the well cement slurry in the mixer. Power number values associated with mixing the well cement slurry in the mixer under the plurality of conditions are identified. Each power number value is based on an amount of energy used to mix the well cement slurry under a respective one of the plurality of conditions. Values for parameters of a functional relationship between power number and Reynolds number are identified based on the power number values and the Reynolds number values for the plurality of conditions.

  • Patent number: 9808960
    Abstract: One example of correlating energy to mix well cement slurry under laboratory conditions to field conditions can be implemented as a method to determine energy to mix cement slurry. Electrical power supplied to an electric mixer in mixing a specified well cement slurry is measured. An energy to mix the specified well cement slurry is determined from the measuring. The determined energy to mix the specified well cement slurry and specifications of field equipment for use in mixing the specified well cement slurry at a well site are compared. The field equipment is a different configuration than the electric mixer. Based on the comparing, it is determined whether the well cement slurry needs redesigning according to capabilities of the field equipment.
