Abstract
A method of installing an internal latch profile in an existing tubular string does not require the use of a packer. In a described embodiment, a method of latch installation includes the step of deforming an interior surface of the tubular string after the tubular string is positioned in a well. In another described embodiment, a method of latch installation includes the step of cutting into the interior surface of the tubular string.
Claims21
A method of installing a latch profile in a tubular string in a subterranean well, the method comprising the steps of:
- positioning the tubular string in the subterranean well;
- then conveying a latch structure into the tubular string;
- orienting the latch structure rotationally relative to the tubular string, including rotationally orienting a muleshoe of the latch structure relative to the tubular string;
- and
- then expanding the latch structure outward in the tubular string.
A method of installing a latch profile in a tubular string in a subterranean well, the method comprising the steps of:
- positioning the tubular string in the subterranean well;
- then conveying a latch structure into the tubular string;
- orienting the latch structure rotationally relative to the tubular string, including rotationally orienting a laterally inclined surface of the latch structure relative to the tubular string;
- and
- then expanding the latch structure outward in the tubular string.
A method of installing a latch profile in a tubular string in a subterranean well, the method comprising the steps of:
- positioning the tubular string in the subterranean well;
- and
- then forming the latch profile in the tubular string, the forming step including:
- conveying the latch profile into the tubular string in an expandable structure, rotationally orienting the expandable structure relative to the tubular string, and outwardly expanding the expandable structure in the tubular string, the expanding step including deforming the tubular string, thereby recessing the expandable structure into the tubular string.
A method of installing a latch profile in a tubular string in a subterranean well, the method comprising the steps of:
- conveying the latch profile in an expandable structure into the tubular string;
- rotationally orienting the expandable structure relative to the tubular string;
- and
- then plastically deforming the tubular string, thereby installing the latch profile in the tubular string.
