METHOD FOR DETERMINING THE MEAN TIME BETWEEN FAILURES OF ESP UNITS

Известия Томского политехнического университета: Инжиниринг георесурсов, 2022
Electrical submersible pumps are widespread in the oil industry, in particular, for production of watered mixture in periodic pumping mode. Intermittent mode allows reducing energy costs due to application of high-rate equipment with higher efficiency and prompt change of well fluid withdrawal during change of well parameters without changing equipment.
