Avoid the need for a large and heavy rig for pulling tubulars or section milling
Avoid having to ship retrieved tubulars or swarf to land
Avoid having to treat contaminated tubulars or swarf on land
Perforate the casing in the same time as it takes to cut the casing
Establish a new barrier around the casing to avoid having to pull casing before setting the cement plug
Maintain well access
Leave the casing in the ground and have a path back in if having to remediate a plug later
Well can be re-opened for CO2 injection in the future
How is the tool operated?
Tool is hydraulically operated (flow).
What sizes are available?
Currently we have a 13 3/8″ version available, but we have verified 9 5/8″ and 20″ capacities also.
Will it damage the 2nd casing?
No, the drill bits will stop just after breaking through the first casing.
What if there is cement behind the casing?
The drill bits are independent of material behind the casing.
What kind of swarf is generated?
A significant amount of design and testing have been put into the drill bit to ensure that the drill bit cuttings break up into small chips (10mm) that fall down and remain in the well. If required, the chips can be retrieved by a magnet below.
