1. A method for recovering a core from a downhole environment, comprising:
providing a measure while coring device and a coring apparatus within a wellbore, wherein the coring apparatus includes an inner tube configured to receive the core, a pressure sealed plug within the inner tube and a pressure relief valve actuatable to relieve pressure within the inner tube;
lowering the measure while coring device and the coring apparatus to an elevation where the core is to be obtained;
positioning the coring apparatus at the elevation where the core is to be obtained;
starting the coring apparatus;
conducting coring operations thereby causing the core to push the pressure sealed plug through the inner tube increasing pressure within the inner tube until the pressure relief valve actuates; and
taking at least one measurement in the inner tube of the coring apparatus during the coring operations.
