Abstract
A method for continuously batch mixing a homogenized cement slurry is provided that includes providing first and second mix tubs which each perform a process which include: receiving a measured quantity of solid and liquid constituents of a cement mixture; mixing the solid and liquid constituents of the cement mixture into a homogenized cement slurry; and delivering the homogenized cement slurry into a well. In this method, the first and second mix tubs alternate these delivering processes in a synchronized manner such that one of the first and the second mix tubs continually delivering its corresponding homogenized cement slurry to a well pumping system.
