NOVELTY - The method involves obtaining first raw measurement from a first borehole (105) within a formation (104). A second raw measurement is obtained from a drilling assembly (190) provided with a drill bit that is formed in a second borehole (109). The first raw measurement and the second raw measurement are processed. The first processed raw measurement is correlated with the second processed raw measurement to identify a predicted formation characteristic ahead of drill bit. An operating condition of drilling assembly is alerted based on predicted formation characteristic.    USE - Method for obtaining deep resistivity measurements for drilling operation in wellbore of subterranean formation for injection well and production well e.g. natural resource production well such as hydrogen sulfide well, hydrocarbon or geothermal well and borehole construction for river crossing tunneling and other tunneling borehole for near surface construction purposes or borehole u-tube pipeline used for transportation of fluid such as hydrocarbon.    ADVANTAGE - Since the operating condition of the drilling assembly is altered based on the formation characteristic, the trajectory of the drilling assembly can be deviated from vertical, or stopping the drilling assembly to avoid penetrating an undesired formation boundary. Since the second processed raw measurement and the first processed raw measurement are correlated to provide survey data, the accuracy of the deep measurement is increased and more lead time can be provided to steer the drilling assembly. Since th downhole tool have a similar sensor configuration and resolution as measurement or logging section, the raw measurements can be correlated without inversion to increase the deep reading accuracy and thus the computational intensity of the deep reading interpretation can be decreased.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a system for optimizing deep resistivity.
