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 1):
A method of plugging a hydrocarbon well, comprising:\n a) deploying a cutting tool downhole to cut helical coils openings out of one or more casings at said section of well to be plugged, wherein said helical coil openings provide access to the annular space external to the outermost casing, wherein the resulting helical casing cuttings fall to the bottom of the well; b) deploying a base plug below and adjacent to said section of well to be plugged; c) deploying a plugging material into said section of well to be plugged, wherein said plugging material rests above said base plug and is able to squeezed out of said helical coil openings while filling said section of well to be plugged; and, d) allowing said plugging material to set, wherein set plug forms a series of rock-to-rock seals through the helical coil opening.
