In Situ Stress Prediction in Subsurface Rocks: An Overview and a New Method

Figure 1

A longitudinal view showing the length and height of the microseismic interpreted hydraulic fractures in different stages. A cross-section of the minimum horizontal stress gradient is also presented in this figure. The dots are observed microseismic events color coded by different stages. The red, white, and blue colors in the background indicate low, middle, and high minimum stress (Sh) gradients, respectively [9].
