Abstract

The metal-to-metal progressing cavity pump is an attractive artificial lift for heavy oils in cold or hot application. The principal objective of this paper is to present the latest developments in numerical simulations tools aimed at understanding and optimizing the operation of a PCP with metallic stator. This paper is divided into three parts: the first focusing on the precise implementation of a viscoplastic thixotropic model while the second is the validation of the numerical models developed around 3D calculations based on a volumetric pump and comparing them to experimental data. The last part is oriented towards the full 3D fluid structure interaction model, used to estimate the stress and strain amplitudes in the metallic stator, to finaly predict its life span or optimize its design.
