Publication number: 20160271834Abstract: 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.Type: ApplicationFiled: October 31, 2013Publication date: September 22, 2016Applicant: HALLIBURTON ENERGY SERVICES, INC.Inventors: Thomas Singh Sodhi, Pauline Akinyi Otieno, Vivek S. Goel, Benjamin John Iverson
