**8. Summary**

The desired objective of fracturing is to develop and effectively produce from a shale reservoir. To ensure a successful fracturing treatment, a proper fracturing technology must be utilized based on the reservoir characteristics as the reservoir mineral content, physical properties, and geological condition. The utilized formation fracturing technique has a different desired environment to achieve the maximal recovery. During the process of fracturing treatment, the content of a fracturing fluid should be checked based on the formation mineral content and physical properties to improve reservoir permeability and reduce formation damage.

The forming of multi-fracture network is the key to obtain an effective hydraulic fracturing treatment in shale reservoirs. If higher treating net pressure is achieved, lower fluid viscosity is used, and larger fracturing scale attempt would be more helpful to form a fully fracture network. The reservoir geological factors also have high attributes, where brittleness index, elastic characteristic of rock mechanical properties, horizontal stress, and existence of natural fractures are useful to obtain better results of fractures developing into multi-fracture network.

Re-fracturing has the potential to re-energize natural fractures and extend and replace low conductivity existing fracture network. Utilizing re-fracture treatment successfully depends on technology that allows access to larger volumes of unconventional reservoirs. Monitoring the effectiveness of well completions helps guide technologies and methods to gain control of the wellbore to maximize EUR and NPV. Re-fracturing treatments have significant impact on production, and economics of unconventional reservoir development and consideration should be taken to determine the best way to achieve successful re-fracturing as production starts to decline.
