Abstract
A wave propagation measurement-while-drilling system is used to determine selected formation and borehole properties. One or more transmitter-receiver pairs are utilized with the transmitter components operating at one or more frequencies to provide a measured data set. A model relating the borehole instrument response to a wide range of formation and borehole conditions is also utilized. Inversion techniques are employed to determine selected formation and borehole parameters of interest and to simultaneously correct the selected formation parametric measurements for the adverse effects of the borehole and formation bed boundaries thereby avoiding serial type corrections which can yield erroneous results in certain frequency ranges.
