Abstract

A bottom hole assembly (BHA) and methods of using the BHA, the BHA having at least one tool configured to move between the interior and the exterior by fluid pumped down a string. The tool is configured to create a hole in a wellbore tubular, such as casing, tubing, or a liner. The BHA includes a ramp positioned adjacent to the tool to guide the tool to engage the tubular. The tool may be a mill configured to cut a hole in the tubular or a punch member configured to punch a hole in the tubular. A packing element of the BHA enables fluid to be pumped down the annulus and through the hole to treat and/or fracture the formation. The tool may be positioned between two packing elements and fluid may be pumped down the string and through a portion of the tool to treat and/or fracture the formation.

Dependent claims

A bottom hole assembly (BHA) comprising:

a housing;
at least one tool positioned within an interior of the housing, the at least one tool configured to selectively move from the interior of the housing through an opening in the housing and configured to create at least one hole in a tubular of a wellbore;
a sub connected to a portion of the housing, the sub having a ramp positioned adjacent to the opening in the housing, the ramp being positioned below the opening in the housing in an annulus between the housing and the tubular of the wellbore:
and at least one packing element configured to selectively isolate a portion of a wellbore;
wherein fluid pressure within the interior of the housing causes the at least one tool to move through the opening in the housing, wherein the ramp is configured to guide the at least one tool to engage a portion of the tubular of the wellbore to create the at least one hole in the tubular.
