    Abstract: A method and apparatus are provided for insulating electrical connections to a resonator from fluid downhole under extreme pressure and temperature conditions downhole. The method and apparatus provide a pliable insulator that maintains electrical isolation between a resonator electrical connection during exposure to high pressures downhole. The insulator is substantially chemically non reactive so that the insulator maintains electrical isolation between the resonator electrical connections during exposure to fluids downhole. The insulator has a thermal coefficient of expansion in a range so that the insulator maintains electrical isolation between the resonator electrical connections during exposure to high temperatures downhole.

    Abstract: The present invention provides a downhole method and apparatus using a flexural mechanical resonator, for example, a tuning fork to provide real-time direct measurements and estimates of the viscosity, density and dielectric constant of formation fluid or filtrate in a hydrocarbon producing well. The present invention additionally provides a method and apparatus for monitoring cleanup from a leveling off of viscosity or density over time, measuring or estimating bubble point for formation fluid, measuring or estimating dew point for formation fluid, and determining the onset of asphaltene precipitation. The present invention also provides for intercalibration of plural pressure gauges used to determine a pressure differential downhole. A hard or inorganic coating is placed on the flexural mechanical resonator (such as a tuning fork) to reduce the effects of abrasion from sand particles suspended in the flowing fluid in which the flexural mechanical resonator is immersed.
