Abstract
According to one aspect of the disclosure, an intercept well for penetrating an existing tubular is drilled. A casing entry tool is provided in the intercept well and operated to form at least one aperture in the wall of the existing casing. The casing entry tool may be oriented toward the target tubular. In some embodiments, a generally concave notch may be positioned on the casing entry tool and adapted to engage with the convex outer surface of the target tubular. In some embodiments, a locking mechanism may retain the orientation of the casing entry tool within the intercept well.
