What happens if breaks? I would like to know more about it.

Our guess is here that you are referring to a natural gas well malfunctioning or “breaking.” Each Marcellus well in Pennsylvania is built in accordance with state regulations that require operators to construct wells with at least four layers of steel and cement. After a string of pipe is set and cemented in place, the well undergoes a pressure test to ensure maximum integrity. If pressure is lost during this test, remediation work is required. Once completed, Marcellus wells are constructed to withstand time and produce safely. Should something occur technology is built into the well design to alert operators when there is a loss in pressure or well integrity is compromised. Well construction and casing regulations were modernized in recent years through revisions to 25 Pa. Code Chapter 78.
