摘要： 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.

摘要： A down-hole drilling apparatus includes a bearing housing defining a longitudinal axis and upper and lower portions. The upper portion of the bearing housing is configured for connection to a drill string, and at least one annular bearing package disposed within the bearing housing. A drill bit is coupled to the bearing housing and rotatable with respect to the longitudinal axis. The drill bit includes a leading body supporting a plurality of cutters thereon for engaging a subterranean rock formation, a shank portion projecting from the leading body, and a mandrel portion engaging the shank portion and defining an inseparable connection therewith. The mandrel portion extends longitudinally into the bearing housing and through the at least one annular bearing package.
