Transmission of microwave power at frequencies from 1 to 11 GHz has been observed through a short, slotted, coaxial line filled with crude oil from each of five wellhead samples collected at Bayou Choctaw (BC) and one sample from a West Hackberry cavern (WH105). An accurate model for the filled slotted line is used to derive the dielectric constant and loss tangent for each oil. The highest loss occurs in oil from BC19 whose loss tangent is 0.0103 at 1 GHz; the lowest, in WH105 whose loss tangent at 1 GHz is 0.0026. These data suggest favorable prospects for high-resolution radar mapping of SPR cavern walls. Sulphur compounds in the oil appear to be the major source of the microwave attenuation. 20 refs., 4 tabs.
