ABSTRACT

LedaFlow® is a transient multiphase flow simulator under development with both 1D and multidimensional capabilities. The LedaFlow 1D model is a mechanistic, multifluid model consisting of mass, momentum, and energy conservation equations for each field (continuous, bubble and droplet), as well as compositional tracking. LedaFlow 1D is one of the core elements of the suite of computational tools, providing boundary conditions for the more complex, multi-dimensional simulations, as well as serving as a stand-alone feature, similar to other transient 1D codes.

In this paper, a brief overview of the current state of the LedaFlow 1D models is presented. The focus is on the application of LedaFlow1D to field cases, for both pipelines (horizontal and inclined) and wells, for both gas/condensate and oil/gas systems. The ability of the model to predict accurately hold-up, pressure drop, and flow regime under steady state and transient conditions will be demonstrated.
