| 主权项 | 1. A method of pumping production fluid from a wellbore, comprising: deploying a centrifugal pump into a production wellbore; and pumping hydrocarbons from the production wellbore by rotating an impeller of the centrifugal pump in the production wellbore from surface using a drive string, wherein: the impeller is rotated at a speed less than or equal to seventeen hundred fifty revolutions per minute, andthe centrifugal pump comprises a thrust bearing receiving thrust from a shaft of the centrifugal pump and being lubricated by the pumped hydrocarbons. | ||
