Using a special core bit, a solid cylinder of rock, approximately 4" - 5" in diameter and in 30 ft increments, is extracted from a well. Conventional core sampling is generally available over short reservoir sections and is helpful when needing analysis on a detailed scale. The wealth of information available from a conventional core makes it the most accurate fundamental tool available in understanding oil and gas reservoirs.
