Abstract
Systems and methods presented herein provide for a segmented expanding gun for plug and abandon downhole applications. The expanding gun can include a first ring of multiple shaped charges. First and second charges in the ring can be identically shaped and contiguous. The first ring expands radially to deploy the shaped charges on a tubular wall. Multiple rings can be stacked and offset axially.
Claims21
A segmented radial cutter, comprising:
- a first ring of multiple shaped charges, wherein a first charge and a second charge in the first ring are identically shaped and contiguous;
- and
- a downhole tubular, the first ring being positioned within the downhole tubular,
- wherein the first ring expands radially to deploy the shaped charges against an inner surface of the downhole tubular.

A method for plugging and abandoning a wellbore, comprising:
- lowering a first ring of multiple shaped charges into the wellbore, wherein a first charge and a second charge in the ring are identically shaped and contiguous,
- when the first ring is at a target depth, expanding the first ring radially;
- and
- when the first charge is against a tube wall, activating the shaped charges.
