This chapter presents an overview of coring tools, including guidelines for selecting coring tools for specific applications. Coring provides the only means of obtaining high quality samples for the direct measurement of rock and reservoir properties. Cores provide both geological and engineering information, and their analysis ultimately leads to a profitable field development. | This chapter presents an overview of coring tools, including guidelines for selecting coring tools for specific applications.
