Abstract:
A method for creating access to annular spacing during P&A operations is described. Specifically, helical coils are cut into one or more casings before the plugging material is set. The plugging material is able to exit the helical coils, forming multiple, small rock-to-rock seals.

Claim (Index 17):
An improved method of plugging a well, wherein said method comprising removing tubing and casing, setting a base plug and a plug, said improvement comprises cutting a helical coil through said casing to make a resulting helical coil opening instead of removing the casing so that said plugging material can pass through said resulting helical coil opening to form a rock-to-rock seal above said base plug.
