Hopper Hans Paul: Controlling artificial lift in wells. British Petroleum Co, May 25, 1988: GB2197675-A (33 worldwide citation)

Crude oil production from a well is stimulated by artificial lift. To control the artificial lift and hence the production of oil, a choke unit 112 associated with a natural flow production well is modified so that the artificial lift fluid is passed through the choke 212 itself and the crude oil is ...
