This work presents a modeling tool to use in sizing an electrical submersible pump system in a solution-gas-drive horizontal well. The model combines reservoir inflow performance, tubing or outflow performance and the pump performance for a nodal analysis which will determine the staging and brake horsepower requirements of an electrical submersible pump system.
There is flexibility bui lt into the model to examine the severe gas slugging problems which are characteristic of a horizontal well. An option is available for including a gas separator in the design. A correlation which indicates head degradation and/or possible surging of the pump due to h igh gas intake is examined.
Through the use of this model, electrical submersible pumping equipment can be selected which will optimize on-line performance for a well. The model can be employed also to aid in the pre-drilling evaluation of a horizontal well in the event that artificial lift might be required.
