Abstract
The invention generally relates to an apparatus and a method for conveying and operating tools in a wellbore. In one aspect, a method of performing an operation in a wellbore is provided. The method includes running a selectively separable plug member accommodating a tool into the wellbore on a continuous rod and positioning the separable plug member adjacent a receiver member disposed in the wellbore. The method further includes manipulating the weight of the continuous rod to seat the separable plug member in the receiver member. In another aspect, a plug assembly for use in a wellbore is provided.
Claims21
A method of performing an operation in a wellbore, comprising:
- running a selectively separable plug member accommodating a tool into the wellbore on a continuous rod,
- positioning the separable plug member adjacent a receiver member disposed in the wellbore;
- and
- manipulating the weight of the continuous rod to seat the separable plug member in the receiver member.
A method of performing an operation in a wellbore, comprising:
- running a selectively actuatable plug member into the wellbore on a continuous solid rod, wherein the plug member accommodates at least one tool;
- actuating the plug member by manipulating the weight of the continuous solid rod, thereby separating a first portion of the plug member from a second portion;
- and
- using the continuous solid rod to run the second portion with the at least one tool to a predetermined location below the first portion to perform the operation.
A plug assembly for use in a wellbore, comprising:
- a first portion configured to be attachable to a solid continuous rod, the first portion having a plurality of setting rings constructed and arranged to expand upon application of a force, wherein each pair of setting rings is interconnected via a spacer ring;
- a second portion configured to accommodate at least one wellbore tool;
- and
- a selectively actuatable member for connecting the first portion to the second portion, whereby the selectively actuatable member allows the second portion to separate from the first portion upon application of a predetermined force.
