<p>The injection system (10) has an injection device (20) for driving a fluid flow in a reservoir of the geological formation (200) with a pump (22) and an injection borehole (24) in the reservoir of the geological formation. A control unit (30) is provided for controlling the fluid flow through the injection device and a sensor system (40) has a fluid sensor (44) for monitoring the fluid flow inside the reservoir of the geological formation. The sensor system is connected with the control unit in signal communicating manner. Independent claims are included for the following: (1) an oil supply delivery system with a promotion bore; and (2) a method for controlling an injection system for the supply of oil from a reservoir of geological formation.</p>
