A setting tool for setting a well tool in a wellbore includes a setting mechanism which is operative to apply a setting force to set the well tool, and an orientation indicator which indicates an orientation of the setting tool. A method of setting a well tool and engaging an assembly with the well tool includes setting the well tool in a wellbore utilizing a setting tool which includes an orientation indicator, and then engaging the assembly with the well tool, thereby fixing an orientation of the assembly relative to the well tool. A method of azimuthally orienting a whipstock in a wellbore includes setting an anchor in the wellbore, the anchor including an alignment device, and indicating an azimuthal orientation of the alignment device relative to the wellbore. The anchor setting and azimuthal orientation indicating are performed using only a single trip into the wellbore.

Directional setting tool and associated methods

An apparatus and methods for sidewall percussion coring service are disclosed. In some embodiments, the side-wall percussion coring tool includes a voltage activated igniter, explosive material, and a core barrel in communication with the explosive material, wherein activation of the igniter causes detonation of the explosive material to propel the core barrel from tool. Some method embodiments for performing sidewall percussion coring service using the disclosed sidewall percussion coring tool include positioning the tool within a wellbore, activating the voltage activated igniter housed within the tool, detonating the explosive material within the tool with the voltage activated igniter, propelling a core barrel from the tool into the surrounding formation by detonation of the explosive material, retrieving the core barrel from the formation, and removing the tool from the wellbore.
