Abstract
A wellbore intervention tool includes a housing and a means for locking the housing at a selected position inside a first wellbore pipe. The tool includes means for penetrating the first wellbore pipe extensible from the housing. The means for penetrating includes means for measuring an amount of extension thereof or an amount of force exerted thereby such that the means for penetrating is controllable to penetrate the first wellbore pipe without penetration of a second wellbore pipe in which the first wellbore pipe is nested.
Claims28
A wellbore intervention tool, comprising:
- a housing;
- means for locking the housing at a selected position inside a first wellbore pipe;
- means for penetrating the first wellbore pipe extensible from the housing, the means for penetrating comprising means for measuring an amount of extension thereof or means for measuring an amount of force exerted thereby such that the means for penetrating is controllable to penetrate the first wellbore pipe without penetration of a second wellbore pipe in which the first wellbore pipe is nested;
- at least two swivels disposed at spaced apart locations along the housing and a motor disposed in part of the housing wherein a portion of the housing disposed between the at least two swivels is rotatable with respect to a rotationally fixed portion of the housing;
- and
- a gripping and retracting device extensible from the housing and configured to retract lines disposed externally to the first wellbore pipe through an opening cut in the first wellbore pipe by the means for penetrating.
A method for wellbore intervention comprising:
- moving a wellbore intervention tool to a selected position inside a first wellbore pipe nested within a second wellbore pipe;
- locking the wellbore intervention tool at the selected position;
- cutting at least one opening in the first wellbore pipe;
- performing at least one intervention operation using the at least one opening in the first wellbore pipe;
- removing the wellbore intervention tool and the retrieved tube from the first wellbore pipe;
- cutting at least one line mounted to an exterior of the first wellbore pipe;
- and
- withdrawing the at least one line into an interior of the first wellbore pipe, and withdrawing the at least one line and the wellbore intervention tool from the first wellbore pipe.
