Analysis of Hydraulic Fracture
Propagation after Fracture Connection to Joint
Related laboratory microscopic experiments denote that the evolution of hydraulic fractures
(or cracks) is the damage evolution with initiation, extension of many microfissures due to the impact of external load and hydraulic pressure [3, 4]; additionally, gas drainage in damaged coal-rock mass after fracturing is a process with coal-rock mass deformation and gas flow coupling.
In these pseudo-3D models, the hydraulic fracture
network (HFN) is made up of two sets of cracks.
The stress intensity factors of hydraulic fracture
were calculated with the interaction integral
According to ESG, quickly and accurately detecting seismicity near to, or associated with, hydraulic fracture
operations is key to avoiding costly shutdowns and wellbore damage.
Microseismic mapping showed that hydraulic fracture
in shale was a complex fracture network system which consisted of multiple irregular fractures  as shown in Figure 1.
completion technology." (31) Specifically, the
Some of the examples of such scenarios or potential candidate (reservoirs), where hydraulic fracture
job might be required are given below (Craft and Holden 1962):
modeling was validated by both mini- and post-fracture measurements to establish a scientific basis for hydraulic fracturing, which until that time was more an art than a science.
During the next forty years George Mitchell and other geologists developed use of the hydraulic fracture
in North Texas.
We emphasize, however, there is no conspiracy between the oil and gas industry and government regulators to create a false impression that hydraulic fracture
stimulation is safe.
