Paper presented at the SPE Gulf Coast Section - Electric Submersible Pumps Symposium, October 2–6, 2023
Paper Number: SPE-214730-MS
... Abstract Electric submersible pumps (ESPs) are widely used in both onshore and offshore oil fields. However, the impeller of an ESP has strong fluctuation and obvious disturbance structure under the condition of gas-liquid two-phase flow, which leads to significant performance degradation...

... the first implementation of hardened ESP stages in the Northern Llanos Field. The impellers used in the ESP system are made of a special alloy called Ni-resist Type 4. This alloy improves the resistance to erosion and abrasion over a traditional pump stage made of Ni-resist Type 1. A candidate well...
