Correlating Energy to Mix Cement Slurry under Different Mixing Conditions
First Claim
1. A method to determine energy to mix cement slurry, the method comprising:
- measuring electrical power supplied to an electric mixer in mixing a specified well cement slurry and determining an energy to mix the specified well cement slurry from the measuring;
comparing 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, the field equipment being of a different configuration than the electric mixer; and
based on the comparing, determining whether the well cement slurry needs redesigning according to capabilities of the field equipment.

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.
