## Abstract

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 defining a path configured to guide one or more guide taps/fingers of a downhole tool away from the opening.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

A well component according to claim 1, wherein the deflector surface spans a larger circumferential sector of the main bore than the opening does.

### Claim 3 (depends on 1)

A well component according to claim 1, wherein the well component is a side pocket mandrel, the side pocket mandrel having a laterally offset side pocket bore, and where the opening extends between the main bore and the laterally offset side pocket bore.

### Claim 4 (depends on 1)

A well component according to claim 1, wherein the well component is selected from a group consisting of a blow out preventer, a valve, a pipe, a chemical injection sub, and a gas injection sub.
