Medusa® section milling and cutting technology was developed to meet the need for a cost-saving, permanent and verifiable 360-degree barrier to be placed in the wellbore without the need to cut/pull and dispose of casing strings, or conduct lengthy and expensive pilot milling.
Sustained Casing Pressure (SCP) existing between multiple casing strings in a well presents enormous challenges for the Operator tasked with permanently abandoning that well. Often, SCP is present in multiple casing annuli requiring multi string section milling to mitigate. Some of the key challenges to a successful single or dual string section milling operation are:
Fortunately, through experience and technological development, Abrado's unparalleled range of Medusa® section milling tools address all of the above challenges related to single and dual string section milling of windows and provide the least risky route to success for achieving Permanent and Verifiable P&A.
