Abstract
A sampling apparatus, comprising a primary flowline, a secondary flowline, a dump flowline not provided downstream of the secondary flowline, and a relief valve provided in the dump flowline, may be disposed in a wellbore penetrating a subterranean formation. A method of use of the sampling apparatus may comprise flowing fluid from the subterranean formation and into the primary flowline; diverting fluid from the primary flowline to a sample chamber through the secondary flowline; diverting fluid from the primary flowline to the wellbore through the dump flowline; and controlling the pressure in the sample chamber using the relief valve. The sampling apparatus may be used to terminate storage of a fluid sample in a sample chamber while continuing to pump fluid from the formation.
