Bottomhole tool and a method for enhanced oil production and stabilization of wells with high gas-to-oil ratio

A method of optimizing of oil production from an oil well comprising steps as follows:

• (a) determine a dependence of the oil flow rate on the bottomhole pressure in said well and create an IPR curve;
• (b) install a bottomhole tool at the bottom of said well, said tool incorporating a fluid resistor with a movable needle, said resistor and said needle having respective predefined geometries, whereby a position of said needle within said resistor in combination with said geometries defining a fluid resistance through said fluid resistor and a bottomhole pressure in said well, said needle being driven to said position by a driving means controlled from a surface;
• (c) defining a lift curve and its intersection with said IPR curve by adjusting the bottomhole pressure from the surface;
• and
• (d) creating a desired point of operation of said well by shifting the intersection between said lift curve and said IPR curve to a desired location via moving of said needle by said driving means.
