Interactive comment on “ In situ hydromechanical responses during well drilling recorded by distributed fiber-optic strain sensing ” by Yi Zhang

Overall Comments: This manuscript presents the strain variation along two observation boreholes as a response to borehole drilling. For such a purpose, a distributed strain measurement along the two observation boreholes was conducted. The results present the effect of drilling via inducing hydromechanical deformations on the observation boreholes. Moreover, a simple hydraulic diffusion model was implemented to interpret the strain evolution in the observation boreholes. In general, this manuscript is reasonably well organized and English language errors are minor. Although the experimental part of the manuscript is innovative and nicely described especially the application of the Rayleigh spectrum for strain measurement, the numerical part of the manuscript is trivial. The authors had tried to explain the hydromechanical responses
