Estimating Electrical Permittivity
12 May 22
A method of determining the electrical permittivity εkf of a region of a subsurface formation surrounding a drilled borehole includes: obtaining an assumed electrical permittivity εLWD; obtaining resistivity data comprising a first resistivity value Rp determined by analysing the phase delay d of an electromagnetic signal traversing said region and a second resistivity value Ra determined by analysing the attenuation α of the electromagnetic signal traversing said region; and calculating the electrical permittivity of the region from the first and second resistivity values and the assumed electrical permittivity by applying a plane wave approximation to the propagation of said electromagnetic signal across said region.
