We present a novel method to model microseismic event detection and location capabilities of a fiber optic cable. We show how different wrapping angles affect recorded amplitudes of P- and S-waves on fibers with different wrapping angle. We then introduce the Fiber Illumination as a proxy for how well events can be detected on sections of the fiber above a certain SNR.

Furthermore, we investigate the location capabilites of different well paths if instrumented with a fiber.
