Claim:
1. A method for obtaining deep resistivity measurements, comprising: obtaining a first raw measurement from a first borehole within a formation; obtaining a second raw measurement from a drilling assembly disposed in a second borehole within the formation, wherein the drilling assembly comprises a drill bit, and wherein the second raw measurement corresponds to a portion of the formation ahead of and around the drill bit; processing the first raw measurement and the second raw measurement; correlating the first processed raw measurement with the second processed raw measurement to identify the position of the drill bit; applying interpolations to a numerical inversion of the first raw measurement or to the first processed raw measurement to identify a predicted formation characteristic ahead of the drill bit; and altering an operating condition of the drilling assembly based, at least in part, on the predicted formation characteristic.
