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.
