Abstract
A downhole fluid analysis device includes a piezoelectric helm resonator, an optical sensor, and an electromagnetic spectroscopy sensor. The piezoelectric helm resonator includes a strain bar and a pair of electrodes coupled to opposite sides of the strain bar. The piezoelectric helm resonator further includes a pair of tines, in which a first tine of the pair of tines is coupled to opposite ends of the strain bar, the pair of tines each having an arc, and such that strain across a transverse face of the strain bar generates a resonance response from the pair of tines. The optical sensor is positioned centrally with respect to the piezoelectric helm resonator, and the spectroscopy sensor is positioned symmetrically with respect to the piezoelectric helm resonator in at least on direction.
