ABSTRACT:
The present invention provides disclosure of a core sampler that includes a rotatably extending outer barrel containing a relatively non-rotating core barrel which is extendable with the outer barrel in response to drilling mud pressure into the material to be cored by a mud turbine which rotates the outer barrel. The core sampler may be run in and out of a drill string on a wire line.
