... parameters so as toachieve the purpose of increasing production. It studies the factors that could affect that connection. It is found that the density of natural fractures and cavitiesin the reservoir is the main factor affecting the fracture propagation shape. Meanwhile, the liquid containing cavitiesin...

... Abstract The productivity and injectivity of hydraulically fractured geothermal wells in naturally fractured formations depends on the connectivity of fracture networks created by the interaction of hydraulic fractures with natural fractures. The primary objectives of this paper...

... results. The workflow is based on the combination of finite element method and ensemble method. Finite element method is used to establish a forward simulation to study fracture initiation and propagation under the effect of natural fracture. Ensemble method is adopted in the backward calibration process...

... Abstract This paper presents a 3D numerical study on the mechanical behaviors of natural fracture under injection loading, and further proposes a practical workflow for designing a widened safe mud weight window (MWW) for drilling subsalt well sections with natural fractures. The original safe...

... was not totally excluded. Natural fractures have been observed in some of the core samples, which were modeled using 3D seismic curvature analysis. The model suggests that the dominant location of the fractures is where the most deformation of the structure occurred. Knowing where the most probable location...
