“…BIB-SEM investigations found that the majority of the visible porosity (N10 nm) is associated with inorganic and not with organic matter for these two shales (Klaver et al, 2015). The productive intervals are between 9700 and 15,300ft (3000-4600 m) and the main exploration and production efforts for these heterogeneous shales are focused in an area situated roughly along the center of the Texas and Louisiana border in the U.S. (Hammes and Frébourg, 2012).…”

“…The Bossier and Haynesville shales comprise a number of different Upper Jurassic marine lithofacies ranging from argillaceous to carbonate-dominated as well as organic-rich to organic-poor mudrocks (Hammes and Frébourg, 2012). Typical TOC contents of the Haynesville shale are 3%, with porosity values ranging between 8 and 12%, ranging in vitrinite reflectance (VR r ) between 2.2 and 3% (Jarvie, 2012;Williams, 2009).…”

“…Although shale gas abundantly exists in boring "homogeneous" like fine-grained mudstone, it actually has obvious vertical heterogeneity in terms of lithofacies, mineralogy, petrophysics, gas content variation which determines the sweet spots, gas fairways, or producible areas of economic potential (Vecoli et al, 2009;Hulsey, 2011;Abouelresh and Slatt, 2012;Slatt and Rodriguez, 2012;Hammes and Fr ebourg, 2012). Many studies also have been carried out to figure out the controlling factors that lead to the vertical heterogeneity of shale.…”

“…Many studies also have been carried out to figure out the controlling factors that lead to the vertical heterogeneity of shale. These studies found that redox conditions, biological productivity, preservation, and relative sea-level change directly contributed to the vertical heterogeneity of shale (Algeo et al, 2004;Singh, 2008;Challands et al, 2009;Hulsey, 2011;Hammes and Fr ebourg, 2012;Slatt and Rodriguez, 2012). Because gas shales have historically been thought as homogeneous, understanding the vertical heterogeneity of shale has far-reaching implication.…”

“…In many shales, they are vertically stacked in systematic patterns rather than randomly distributed stratigraphically [29][30][31][32][33][34]. An upward decrease in API gamma-ray count from the base of an interval is the most common pattern on Barnett Shale gamma-ray logs; such a pattern is named a 'parasequence' [35] (Figure 9).…”

Abstract:The revelation of vast global quantities of potentially productive gas and oil-prone shales has led to advancements in understanding important geological properties which impact reservoir performance. Based upon research on a variety of shales, several geological properties have been recognized as being common and important to hydrocarbon production.(1) transport/depositional processes include hemipelagic 'rain', hyperpycnal flows, turbidity current flows, tempestites , wave-reworking, and contour currents in both shallow and deep water settings. (2) Common shale minerals include clays, quartz, calcite, dolomite, apatite, and pyrite; organic constituents include spores (Tasmanites), plant remains, biogenic quartz and calcite, and arenaceous foraminifera. (3) Porosity and permeability are characteristically low with pore sizes ranging down to the nanoscale. Main pore types include intergranular (including pores within clay floccules), porous organic matter, porous fecal pellets, and microfractures. (4) Important geochemical characteristics include organic richness (>3%), maturity (>1.1%Ro for shale gas and 0.6-0.9% for shale oil) and type (I-IV), in addition to certain biomarkers which are indicators of bottom water oxicity during deposition. Remaining hydrocarbon potential [RHP = (S1 + S2)/TOC] also reflects temporal environmental changes. 'Isotopic reversals' can be used to detect best producing areas in shale-gas plays. (5) Lithofacies stacking patterns and sequence stratigraphy are the result of eustatic depositional history. A general sequence stratigraphic model is presented here that highlights this commonality. (6) Geomechanical properties are key to drilling, fracturing and production of hydrocarbons. Brittle-ductile couplets at several scales occur in shale sequences. (7) Geophysical properties, when calibrated to rock properties, provide a means of regionally to locally mapping the aforementioned properties. (8) Economic and societal considerations in the exploration and development of resource shales are garnering attention. Many potentially economic shale-gas and shale-oil plays are being identified globally. Risks and uncertainties associated with gas-and oil-rich shales include the lack of long-term production histories, environmental concerns related to hydraulic fracturing, uncertainty in calculating hydrocarbons-in-place, and fluctuations in supply, demand, and price.
