Paper: Static Dynamic Modeling of ESP Wellbore Applications

With the evolution of design and evaluation software for Electric Submersible Pump (ESP) systems over the last 25+ years, most of the development and emphasis has been on ESP design, or sizing. All of the ESP manufacturers have, at one time or another, been involved in internal development of ESP sizing software and there have also been several third party companies who have developed similar programs. This paper will introduce the expansion of a design and sizing software program into a tool, which can be utilized for time variable modeling and simulation. AutographPC@ Software version 4.0 is the latest in the third generation of ESP design software from Centrilift. With this release, the design capability has been expanded to include an ESP system simulator. This simulator adds the time variable to the sizing, in such a way that the user can see the dynamics of the well operation in conjunction with the ESP operating point.
