A method of measuring resistivity values in relation to the azimuthal displacement of a measurement sensor displayed on a measurement-while-drilling device in a wellbore environment is disclosed. Preferably, the \u2014CHR, \u2014CHRf, \u2014CHF, andor \u2014CH2 groups are contained within partially fluorinated alkenes. The fitting component includes a base with a bottom and sidewalls that define a channel and a plurality of sets of raised projections.
