He also designed a device for undersea drilling and oil extraction (a drilling rig), becoming an absolute world pioneer in this field. He developed and gave the oil workers a device for measuring the curvature of shafts and a device for measuring the perpendicularity of drilling mining holes. He designated offshore oil plots, specifying their abundance, and established natural deposits in this area.
