the cylindrical section of rock or sediments

obtained when a core barrel with

an annular bit is withdrawn from a well

Sidewell cores

cylindrical sections of rock or sediments

obtained by shooting hollow cylinders of

steel into the wall of the well bore and

subsequently recovering them together

with their contents

Core barrel

the hollow pipe section above the annular

bit that collects and holds a core
