Abstract
A method of interconnecting wellbores is provided which is convenient and economical in its performance. In a described embodiment, milling is not required for forming an opening through a sidewall of casing positioned in a parent wellbore. Instead, an appendage is formed from the casing sidewall and deformed outwardly into a void. A lateral wellbore may then be drilled through the casing sidewall. A liner may be positioned in the lateral wellbore and attached to the appendage.
