Utilizing dissolvable metal for activating expansion and contraction joints
A system, tool and method of providing the tool downhole is disclosed. The tool is conveyed downhole on a tool string. The tool includes a first member and a second member locked in a first configuration by a locking member. The locking member is dissolvable upon introduction of a dissolving agent to the locking member. Dissolving the locking member allows motion between the second member and the first member.
1. A method of providing a tool downhole, comprising:
conveying the tool on a tool string into a wellbore to a selected downhole location, wherein the tool includes a first tubular member having a hole passing through a wall of the first tubular member, a second tubular member having a notch at its outer surface and a locking member extending through the hole of the first tubular member and into the notch of the second tubular member to maintain the first tubular member and the second tubular member in a first configuration;
pumping a dissolving agent to the downhole location to dissolve the locking member; and
moving the second tubular member within the first tubular member relative to the downhole location.
2. The method of claim 1 , wherein the locking member is at least one of: (i) a bearing; (ii) a lug; (iii) a screw; (iv) a collet; (v) a sleeve; and (vi) a dog.
3. The method of claim 1 , wherein the first tubular member is an upper housing of the tool string and the second tubular member is a lower housing of the tool string.
4. The method of claim 1 , further comprising performing a downhole operation using the tool, wherein the downhole operation is one of: (i) a frac operation; (ii) a production operation; and (iii) a completion operation.
5. The method of claim 4 , wherein performing the downhole operation further comprises moving the first tubular member and the second tubular member to a second configuration.
6. The method of claim 4 , wherein performing the downhole operation further comprises producing motion between the first tubular member and the second tubular member.
7. A wellbore system, comprising:
a tool string conveyable to a downhole location in a wellbore, the tool string including a tool having a first tubular member having a hole passing through a wall of the first tubular member and a second tubular member having a notch in its outer surface;
a locking member configured to extend through the hole of the first tubular member and into the notch of the second tubular member maintain the first member and the second member locked in a first configuration, wherein the locking member is dissolvable upon introduction of a dissolving agent to the locking member and wherein the second member moves within the first member relative to the downhole location when the locking member is dissolved; and
a pump configured to pump the dissolving agent to the downhole location to dissolve the locking member.
8. The system of claim 7 , wherein the locking member is at least one of: (i) a bearing; (ii) a lug; (iii) a screw; (iv) a collet; (v) a sleeve; and (vi) a dog.
9. The system of claim 7 , wherein the first tubular member is an upper housing of the tool string and the second tubular member is a lower housing of the tool string.
10. The system of claim 7 , wherein the tool is configured to perform a downhole operation that is at least one of: (i) a frac operation; (ii) a production operation; and (iii) a completion operation.
11. The system of claim 10 , wherein the tool performs the downhole operation by moving the first tubular member and the second tubular member to a second configuration.
12. The system of claim 10 , wherein the tool performs the downhole operation via producing a motion between the first tubular member and the second tubular member.
13. A tool string for use in a wellbore, comprising:
a first tubular member having a hole passing through a wall of the first tubular member;
a second member having a notch in its outer surface;
a dissolvable locking member configured to maintain the first member and the second member locked in a first configuration and bear a load of the lower of the first tubular member and the second tubular during conveyance of the tool string to a downhole location, wherein the second member moves within the first member relative to the downhole location when the locking member is dissolved; and
a pump configured to pump a dissolving agent to the downhole location to dissolve the locking member.
14. The tool string of claim 13 , wherein the locking member is at least one of: (i) a bearing; (ii) a lug; (iii) a screw; (iv) a collet; (v) a sleeve; and (vi) a dog.
15. The tool string of claim 13 , wherein the first tubular member is an upper housing of the tool string and the second tubular member is a lower housing of the tool string.
16. The tool string of claim 13 , wherein tool string is configured for use in at least one of: (i) a frac operation; (ii) a production operation; and (iii) a completion operation.
17. The tool string of claim 13 , wherein the tool string is configured to perform a downhole operation by performing at least one of: (i) an operation that moves the first tubular member and the second tubular member from the first configuration to a second configuration; and (ii) an operation that produces a motion between the first tubular member and the second tubular member during the operation.
