procedure of mill out the cement plug

Baker Hughes TechConnect, Volume 10, Number 3

Baker Hughes drills out 79 composite plugs in two wells with one mill. Baker Hughes applied its METAL MUNCHER™ AMT milling technology to mill out 79 composite plugs in two wells in one trip, eliminating nonproductive time and substantially reducing rig time. The operator, drilling an unconventional oil well in the Bakken shale, had run two plugandperf completions.

2 Well plugging and abandonment techniques Global CCS

Abandonment plugs consist of tailored cement types that may be supported by mechanical plugs. In order to effectively seal a well, a stepwise procedure for plugging and abandoning wells was described by Fields and Martin (1997), addressing the removal of equipment and tools, cleaning the wellbore, plugging and testing.
