Fracture determination ahead of the tool

A system comprising:

• a bottom hole assembly into a wellbore, wherein the bottom hole assembly comprises:
• a transmitter sub comprising a transmitter coil configured to generate an electromagnetic wave into a subterranean formation;
• and
• a first receiver sub comprising a first receiver coil configured to receive a plurality of response signals with the first receiver coil from a direction comprising an x-direction, a y-direction, or a z-direction, wherein the plurality of response signals are from two or more depths and are formed from the electromagnetic wave interacting with the subterranean formation;
• and
• an information handling system communicably coupled to the bottom hole assembly configured to:
• analyze a gradient of the response signals, wherein the gradient of the response signals is indicative of formation resistivity in the direction and across the two or more depths;
• detect a change in the gradient of the response signals, wherein the change in the gradient of the response signals is indicative of a change in the formation resistivity in the direction;
• and
• determine if the change in the gradient of the response signals exceeds a threshold, wherein the threshold indicates a presence of a fracture or a fault in the formation.
