Abstract
A system includes a wear bushing retrieval tool. The wear bushing retrieval tool an annular main body configured to be disposed about a tubular string, a plurality of locking dogs, wherein each locking dog of the plurality of locking dogs is pivotably coupled to the annular main body, a first axial securement feature coupled to the annular main body, and a second axial securement feature coupled to the main body, wherein the first and second axial securement features are configured to cooperatively axially capture a coupling of the tubular string when the annular main body is disposed about the tubular string.
Claims20
A system, comprising:
- a wear bushing retrieval tool, comprising:
- an annular main body configured to be disposed about a tubular string;
- a plurality of locking dogs, wherein each locking dog of the plurality of locking dogs is pivotably coupled to the annular main body;
- a first axial securement feature coupled to the annular main body;
- and
- a second axial securement feature coupled to the annular main body, wherein the first and second axial securement features are axially offset from one another by an axial offset distance relative to a central axis of the annular main body,
- wherein the first and second axial securement features are configured to cooperatively axially capture a coupling of the tubular string via the axial offset distance when the annular main body is disposed about the tubular string and the wear bushing retrieval tool at least partially axially overlaps with the coupling.
A method, comprising:
- running a tubular string into a wellbore through a wellhead;
- disposing a wear bushing retrieval tool about the tubular string;
- axially capturing a coupling of the tubular string with a first axial securement feature and a second axial securement feature of the wear bushing retrieval tool;
- running the wear bushing retrieval tool into the wellhead with the tubular string;
- landing the wear bushing retrieval tool against a wear bushing disposed within the wellhead;
- engaging a plurality of locking dogs of the wear bushing retrieval tool with a groove of the wear bushing;
- decoupling the wear bushing retrieval tool from the tubular string by releasing at least one of the first or second securement features from the coupling of the tubular string;
- and
- retrieving the wear bushing retrieval tool and the wear bushing from the wellhead separate from or without the tubular string.
A system, comprising:
- a wear bushing retrieval tool, comprising:
- an annular main body configured to be disposed about and coupled to a tubular string;
- a plurality of coupling features, wherein each coupling feature of the plurality of coupling features is coupled to the annular main body via a respective hinge;
- a first key pivotably coupled to the annular main body, wherein the first key is configured to extend radially inward relative to a central axis of the annular main body and engage the tubular string;
- and
- a second key pivotably coupled to the annular main body, wherein the second key is configured to extend radially inward relative to the central axis of the annular main body and engage the tubular string;
- and
- a wear bushing configured to be secured within a wellhead assembly, wherein the wear bushing comprises an annular groove formed in an inner diameter of the wear bushing, and wherein each coupling feature of the plurality of coupling features is configured to radially and axially overlap with the annular groove when the wear bushing retrieval tool is disposed within and landed against the wear bushing.
