Abstract
An apparatus for use in a wellbore may include a tool having a first section configured to receive a core and a second section configured to collect a gas escaping from the core. The apparatus may also include a sensor associated to provide signals relating to a property of gas. In one aspect, the second section may be removable and may be pressurized. The apparatus may also include a recorder that records data representative of the signals received from the sensor. The recorder may record data while the tool is retrieved from the wellbore. A method for estimating a parameter of interest of a formation includes retrieving a core from the formation, collecting a gas escaping from the core as the core is retrieved to the surface, and measuring at least one property of gas while the core is retrieved to the surface.
