Hydraulic fracking strengths and weaknesses

We have long been considered a non- gelled water is one of the most cleanest, most economical fracturing fluid . If the filtration problems in the formation  maide fracturing fluid compatibility issues and minimal case , the non- thickened water as a base fracturing fluid will be of great significance . These stimulation usually refers to  maide hydraulic fracturing benefits ,reducing water resistance or branches fracturing fracturing ( occasionally ) , they usually require a large number of high-speed pumped water containing a small amount of reducing agent and proppant . In the application, compared with the traditional thickening fluid , this method can reduce the capital investment on the one hand , on the other hand so that hydraulic fracturing is more economically viable than other uses thickening fluid fracturing methods. Like other technical measures to increase production and hydraulic fracturing has its advantages , but also has its drawbacks . This particular method is the key to its screening principles will be applied to fit the unique advantages of this region or strata .
maide fracturing proppants potential advantages include:
2 simple operation, the use of a single chemical agents ;
3 can produce a considerable length of hydraulic ;
4 initial production can be compared with the normal stimulation intended ;
5 . Costs lower than normal stimulation .
As expected, the hydraulic fracturing also has shortcomings, such as :
1 confined to the low amount of sand strata ;
2 rapid sand filtration rate ;
(3) the effective fracture length is shorter ;
4 Compared with ordinary fracturing operations of similar size , the larger the decrease in final yield ;
5 The following fracturing aquifer has certain risks.
In essence , the hydraulic fracturing of various unfavorable factors show poor ability to carry proppant fracturing fluid . If the proppant can be effectively carried in place of water , the potential adverse consequences will be significantly reduced or even disappear completely .
