1. A method of performing a wellbore operation with a downhole tool, comprising:
logging wellbore data with a sensor in the tool including data related to a formation surrounding a wellbore over a period of time;
measuring a lateral acceleration of the tool over the period of time with one or more accelerometers embedded in the tool;
double integrating, using a processor, the measured acceleration of the tool over the period of time;
obtaining, using a processor, a displacement of the tool over the period of time from the double integration;
fitting, using a processor, the displacement of the tool over the period of time to a best fit curve, the best fit curve indicative of a lateral deviation of the wellbore;
subtracting, using a processor, the best fit curve from the displacement of the tool over the period of time, the difference between the best fit curve and the displacement of the tool being indicative of a lateral position of the tool relative to the wellbore; and
associating, using a processor, the logged wellbore data with the lateral position of the tool, generating calibrated wellbore data based on the lateral position of the tool with respect to the wellbore.
