... allows for not only these largest two events to be characterized, but for a high-resolution picture of the smaller magnitude seismicity to be constructed. We observe that these two events are separated by a relatively quiescent block that is outlined by lower-magnitude seismicity. Although elevated pore...

... for monitoring microseismic events in the vicinity of injection zone. Moment magnitudes were estimated from single-component DAS data, which was subsequently compared with modeling predictions. In addition to broadband DAS data aimed at detection of micorseismic events, low-frequency DAS data were also recorded...

... Stress directions and magnitudes for horizontal well stimulation are key geomechanics factors to effectively connect tight low permeable reservoir to the wellbore. Stress measurement such as closure pressure interpreted from low rate fracturing tests are usually available only in the pay zone...

..., and if the displacement pressure gradient is greater than 10kPa/m, increasing the displacement pressure gradient has no obvious effect. Reservoir numerical simulation shows that at high water cut stage horizontal wells may increase the magnitude of displacing pressure gradient by 50% to 100%, meanwhile the variation...

.... Earthquake migration can propagate across steps, indicating a transfer of deformation, but can be obstructed by others. Preliminary quantitative results show that whether a step transfers or blocks deformation depends on the separation between the bounding segments relative to the maximum magnitude...
