Abstract
A lockable swivel (4) for use in drilling applications which allows the operator to selectively engage and disengage the swivel (4). The lockable swivel (4) is comprised of a locking mandrel (7) carried in a body (3) which engages, upon actuation, splined surfaces (20,21) within the swivel mandrel (5) thereby locking the two together. Various methods for the use of the lockable swivel (4) in wireline and other drilling operations are demonstrated.

connecting the swivel in the drill string above a rotary table and below the wireline access device; and unlocking the swivel such that the portion of the drill string above the swivel is prevented from rotation while the portion of the drill string below the swivel can rotate freely and thus the drill string below the swivel can be rotated by the rotary table without having to remove the wireline access device.
connecting the swivel in the drill string above a rotary table and below the wireline access device; and unlocking the swivel such that the portion of the drill string above the swivel is prevented from rotation while the portion of the drill string below the swivel can rotate freely and thus the drill string below the swivel can be rotated by the rotary table without having to remove the wireline access device.
7. The method of claim 6 wherein the wireline access device is a side entry sub.
8. The method of claim 6 wherein the wireline access device is a top entry sub.
9. The method of claim 6 wherein the swivel is locked hydraulically.
10. A method of using a swivel in a drill string to perform wireline services, wherein the drill string has a wireline access device, the method comprising the steps of:
connecting the swivel in the drill string above a rotary table and below the wireline access device such that the swivel can alternate from a locked position, in which the portion of the drill string below the swivel does not rotate independently of the portion of the drill string above the swivel, to an unlocked position in which the swivel allows the portion of the drill string below the swivel to rotate independently of the portion of the drill string above the swivel; and selectively alternating the swivel between its locked position and its unlocked position.
connecting the swivel in the drill string above a rotary table and below the wireline access device such that the swivel can alternate from a locked position, in which the portion of the drill string below the swivel does not rotate independently of the portion of the drill string above the swivel, to an unlocked position in which the swivel allows the portion of the drill string below the swivel to rotate independently of the portion of the drill string above the swivel; and selectively alternating the swivel between its locked position and its unlocked position.
11. The method of claim 10 wherein the wireline access device is a side entry sub.
12. The method of claim 10 wherein the wireline access device is a top entry sub.
13. The method of claim 10 wherein the step of selectively alternating the swivel between its locked position and its unlocked position is performed hydraulically.
14. A method to perform drilling services using a top drive assembly, the method comprising:
connecting a lockable swivel to a drill string above a rotary table and below an access sub;
unlocking the lockable swivel;
deploying a tool through the access sub, the lockable swivel, and the drill string;
rotating the drill string below the lockable swivel with the rotary table; and holding the access sub stationary with the top drive assembly.
connecting a lockable swivel to a drill string above a rotary table and below an access sub;
unlocking the lockable swivel;
deploying a tool through the access sub, the lockable swivel, and the drill string;
rotating the drill string below the lockable swivel with the rotary table; and holding the access sub stationary with the top drive assembly.
15. The method of claim 14 wherein sections of drill pipe separate the lockable swivel and the access sub.
16. The method of claim 14 wherein the access sub is a wireline top entry sub.
17. The method of claim 14 wherein the access sub is a wireline side entry sub.
