A percussion-type device (i.e., gun) which can be attached to the well-logging cable, provided with a means of accurately depth-positioning the tool (SP or gamma-ray curve), which is used to obtain formation samples. Hollow. cylindrical core barrels (i.e., bullets) can be shot in sequence, from the gun into the formation. After each core barrel has been fired into the formation wall, it is pulled free and retrieved by wires connecting the barrel to the gun. Core barrels are available for penetrating formations of different hardness. The type of barrel and size of charge are varied to optimize recovery in different formations.
