Inferring fluid-filled fractures presence using S-wave attenuation on microseismic events
Co-authors : GRAUSEM Marc (Total) , Shuck Ted, Diller Dave (Nanoseis)
We disclose a method based on S-wave attenuation to infer fluid-filled fractures using microseismic monitoring. Since S-waves do not propagate through fluids, they offer a way to distinguish between wet (water or oil-saturated) and dry (gas or air-saturated) fractures within the stimulated reservoir. We applied this principle to a hydraulically fractured horizontal wellbore to indirectly map the stimulated fractures.
