Abstract
A downhole tool including a tube having an inner bore that receives a sample of fluid from a subterranean formation, a vibration source and a vibration receiver each at least partially coupled to the tube, and a controller coupled to the vibration source and the vibration receiver is provided. In situ measurements of thermo-physical properties including, but not limited to, fluid density/viscosity, thermal conductivity and heat capacity, and hydrocarbon molecular weight may be provided through the system. The vibrating sensor may include a sensor platform that can be incorporated into sensors purpose built to test different in situ thermo-physical properties that are technically difficult or expensive to test using typical sensors. The vibrating sensors may be modularized and incorporated as a suite of in situ downhole sensors into existing downhole fluid sampling tools, reducing the overall expense of in situ testing.
