Remediation of water and hydrocarbon phase trapping problems in low permeability gas reservoirs; M. Blauch et al. Marcellus shale post-frac flowback waters-where is the salt coming from and what are the implications? E. Brownscombe et al.Shale. Shale is a very fine-grained, clastic sedimentary rock which is made up mostly of clay (defined as particles smaller than 1/256 mm) and which is fissile (tending to break along natural laminations, or planes of weakness, that are less than 1 cm thick). Generally, shale occurs in thin layers or beds and represent low-energy environments ...These perforations allow communication between the well and the shale formation for hydraulic fracturing fluids to be injected into the reservoir rock surrounding the lateral at high pressure. The perforating is done in relatively short segments of the well, typically 150-250 feet long, which are known as stages.The way shaliness affects a log reading depends on the amount of shale and its physical properties. It may also depend on the way the shale is distributed in the formation. Shaly material can be distributed in the formation in three ways: Shale can exist in the form of laminae between which are layers of sand.In summary, the fluid flow in shale formation is controlled both by the pore size and by the properties of pore walls (surfaces). Due to the larger Vt, V2, V3, and smaller surface …The organic-rich siliceous shale primarily includes the shale interval of WF2-3 graptolite bio-zone at the upper part of the Wufeng formation and the shale interval of LM1-4 graptolite bio-zone at the bottom of the Lungmachi formation (Jin et al., 2018).

The upper part of the Early Cambrian sand Formation is composed of glauconitic sandstone which is overlain by gray-green siltstones and shale of Middle Cambrian age.As shale is made of kaolinite, illite, smectite, and montmorillonite, it has an affinity for water. The shale-fluid interaction causes shale instability (Lal, 1999). Therefore, if a shale formation is drilled with a non-inhibitive water-based mud, the shale instability problems occur (Wilcox et al., 1987; Soric et al., 2004; Reid et al., 1992).The problem of wellbore stability in hard brittle shale formations is an important research topic in the exploration and development of shale gas.

This interval is considered to be primarily non-reservoir. The Lower interval of the Point Pleasant Formation is organic-rich calcareous shale (roughly 40%–60% carbonateThis Formation is commonly called Alum Shale because historical raw materials for the production of alum were extracted from this shale. The upper part of the Early Cambrian sand Formation is composed of glauconitic sandstone which is overlain by gray-green siltstones and shale of Middle Cambrian age.n Shale instability. In this example, Pierre shale has been exposed to a mud comprising fresh water and bentonite gel. Because this fluid contains no inhibitors, water has entered the shale causing it to swell and weakening the formation. Continuous flow of mud has eroded the borehole leaving an enlarged hole that would be hard to log and complete.When it comes to applying for a job, having a well-crafted resume is essential.
