Wellbore arrangement

A well component having a main bore and a lateral opening from the main bore, the well component further comprising a deflector surface arranged adjacent the lateral opening on an inner wall of the main bore and longitudinally extending from a location spaced from the opening in a longitudinal direction of the main bore, to a location longitudinally at the same height as and circumferentially spaced from the lateral opening in the main bore, such that the deflector surface defines a path configured to guide one or more radially protruding guide taps/fingers of a downhole tool in a circumferential direction and away from the opening by engagement of the guide taps/fingers with the path so as to turn the downhole tool in the main bore.
