Electric submersible pumps (ESPs) play a key role in oil production, ensuring the transportation of hydrocarbons from wells. Efficient operation and accurate modeling of ESP performance are particularly relevant in the context of non-standard challenges and suboptimal conditions, such as high gas content at the intake. This paper focuses on analyzing ESP performance in the right-hand region of the head-capacity curve. The paper focuses on studying the performance of ESPs in the right-hand region of the head-capacity curve. The capabilities of modern software products for ESP modeling in this region have been assessed. Special attention is given to the impact of free gas on system behavior.
