摘要： A technique facilitates setting of a liner hanger in a casing or within other tubular structures via a setting tool. The liner hanger may be constructed with an expandable hanger body between fixed ends. The expandable hanger body is formed from a material, e.g. metal, sufficiently ductile to undergo plastic deformation as it is expanded into engagement with a surrounding casing or other tubing. The expandable hanger body is expanded via fluid delivered under high pressure by the setting tool. The setting tool has a pressure booster to achieve the desired high pressure. The pressure booster may be in the form of a multi-diameter piston constructed to establish the desired high pressure during a single stroke.

摘要： A retrievable whipstock assembly for a wellbore includes a whipstock including a longitudinal body and an anchor connection, a deflection surface provided on the longitudinal body with a first engagement element, and a drilling assembly including a drill housing and a second engagement element. The second engagement element is selectively extendible between a recessed position and an extended position. In the extended position the second engagement element is engageable with the first engagement element.

摘要： Geologic material in a borehole is weakened by accelerating a projectile into contact with the material. A drill bit is then used to bore through the weakened material. To accelerate the projectile, an endcap is placed in a conduit using a source of gas. The endcap isolates the conduit from the external environment. A projectile is then positioned in the conduit above the endcap. Movable members within the conduit are operated in sequence to enable single endcaps and projectiles to be moved into the conduit. Gas from the conduit is evacuated into an annulus between the conduit and a surrounding conduit, and a propellant material is provided into the conduit. The propellant material applies a force to the projectile to accelerate the projectile into contact with the geologic material. A fluid is circulated down a second annulus outside of the surrounding conduit to contact the drill bit and remove debris.
