... by an excitation provided by an electric field. In this sense, polar characteristics of water molecules allow quantification of volume of water present in the reservoir, independently of salinity. Owing to the shallow depths of investigation, dielectric tools are useful in evaluating residual oil in high...

... a formation evaluation solution based on wireline dielectric dispersion measurements. Using a 1-inch vertical resolution wireline-conveyed device, we polarize the reservoirs with a multi-frequency electromagnetic field and evaluate the formation response to the application of this field. At higher frequencies...

... (black dots) for Nankai Trough experiment. We also evaluated the polarization of vector response of 300 msec. record from first-break. That can give us an initial insight of a mechanical transmission response of the OBSs. Comparing the new OBS and 17in. test OBS can imply difference of the response...
