Abstract
A downhole motor control system may identify a downhole compressible density of a drilling fluid using a downhole temperature and a downhole pressure of the drilling fluid, the drilling fluid including an incompressible portion and a compressible portion, the drilling fluid flowing downhole with a downhole compressible flow component and an incompressible flow component. A downhole motor control system may determine the downhole compressible flow component using the downhole compressible density, a surface compressible density of the compressible portion at a surface location, and a surface compressible flow component of the compressible portion at the surface location. A downhole motor control system may identify a downhole compressible fraction of the drilling fluid based on the downhole compressible flow component and the incompressible flow component. A downhole motor control system may generate a composite flow rate of the drilling fluid based on the incompressible flow component and the downhole compressible fraction.
