Zusammenfassung:A technique involves sampling fluids in a well environment. An expandable packer is constructed with an outer seal layer. At least one sample drain is positioned through the outer seal layer, and a heater element is deployed in the at least one sample drain. In one embodiment, the heater element is deployed proximate a radially outlying surface of the expandable packer. Additionally, a temperature sensor may be positioned proximate the at least one sample drain to monitor temperature in the environment heated by the heater element.
