Abstract
This relates to sidewall coring tools used to obtain samples of the formation through which the wellbore is drilled. It includes a housing which supports a guide means along which the drill bit, core barrel and motor can be moved to extend or retract the cutting bit and core barrel along a selected path. The core barrel is retracted inwardly on a horizontal path and tilted in an upward position such that the outer end of the core barrel is higher than the end near the motor. Means are provided to force the cut core from the barrel into a core container in association with indexing means.
