Hydraulic fracturing of shale gas wells

Because shale gas reservoirs display physical characteristics of low porosity and low permeability , so only a handful of naturally fractured Maide Coal seam gas development in particular can be directly put into production, but most of the shale gas wells after hydraulic fracturing fluid needs to get ideal production. Shale gas wells after hydraulic fracturing , the use of fracture monitoring technology can effectively evaluate the fracturing effect.
Monitoring through the cracks :
a) a better understanding of fracturing , get roughly the size of the cracks to determine whether or not a multi- fracturing cracks ;
b) After extracting yield better situation to determine whether to overwrite the target layer cracks , fractures and natural fractures analyze whether the cross ;
c) fracturing optimization and yield economic evaluation, fracture length and height growth with increasing number of construction scale can be obtained , for optimal fracture design .
So take an accurate understanding of fracture monitoring method is an effective means of expanding shale gas well fracturing .
