Perforator with a mechanical diversion tool and related methods

An apparatus for performing a downhole operation in a wellbore tubular, comprising:

• a well treatment system that supplies a treatment fluid;
• a conveyance device;
• and
• a well tool conveyed by the conveyance device, the well tool including:
• a perforator configured to form at least one hole in the wellbore tubular;
• a restrictor projecting from an outer surface of the well tool and adjacent to the perforator, the restrictor restricting fluid flow through an annulus between the restrictor and the wellbore tubular, and wherein the restrictor has an adjustable outer diameter and is configured to contact the inner surface of the wellbore tubular;
• and
• a flow space that always providing fluid communication between a location uphole of the restrictor and a location downhole of the restrictor, wherein the flow space is sized to allow for the formation of a flow restriction by particles in the treatment fluid, and wherein the flow space includes an opening to receive the treatment fluid from the annulus and carry the treatment fluid across the restrictor to a downhole location;
• wherein the well tool diverts a substantial amount of the treatment fluid through the at least one hole formed by the perforator.

A method of performing a downhole operation in a wellbore tubular, comprising:

• deploying a perforator and a restrictor at a target depth using a conveyance device, wherein the restrictor is disposed at least partially in an annulus between the conveyance device and the wellbore tubular, wherein a gap separates the restrictor and the wellbore tubular;
• activating the perforator;
• opening an at least one hole in the wellbore tubular;
• pumping a treatment fluid into the wellbore tubular only after activating the perforator and opening the at least one hole;
• and
• restricting flow through the gap to divert a substantial amount of the treatment fluid into the opened hole in the wellbore tubular using the restrictor, wherein the gap is sized to allow for the formation of a flow restriction in the gap by particles in the treatment fluid.
