Gas production in most shale plays is achieved by horizontal drilling followed by hydraulic stimulation. Commercial plays always possess high total organic content (TOC), optimum maturity in addition with proper rock "brittleness", which means easily broken and shattered. The former is known as geology "sweet spot", while the later, we try to analyze here, is named as engineer "sweet spot" or "frackable zones". It has been fully demonstrated that geomechanical properties derived from pre-stack inversion possess a great value for horizontal well design and optimizing completions. Besides that, another emerging technology for shale plays, microseismic monitoring, provides the chance to reexamination the fracked zones and get the knowledge of how completion performance goes on. Both techniques were implemented for characterization of target shale before and during hydraulic fracturing in Sichuan Basin.
