“…With increasing thermal maturity, labile OM (i.e., PC) is transformed to inert/residual carbon (Raiswell and Berner, 1987;Seewald, 2003). Inert carbon composes 98% of OM in overmature deep Utica Shale samples with no further potential for hydrocarbon generation (Haeri-Ardakani et al, 2015). Burial temperatures in the Utica Shale are consistent with measured equivalent vitrinite reflectance (VRo eqv. )…”

“…Burial temperatures in the Utica Shale are consistent with measured equivalent vitrinite reflectance (VRo eqv. ) values of samples from intermediate (1.24%) and deep wells (2.1%; Haeri-Ardakani et al, 2015) corresponding to burial temperatures between ∼140 to 180 • C.…”

“…More precisely, the effects of TSR on Mo remobilization are investigated by determining Mo speciation using X-ray Absorption Fine Structure spectroscopy (XAFS) and sulfur isotope measurements of pyrite. The study focuses on sediment intervals displaying high Mo enrichments from black shale samples affected by different levels of thermal maturation ranging from mature (peak oil window) to over-mature (dry gas zone; Haeri-Ardakani et al, 2015). Implications for the use of Mo as a paleo-redox proxy are discussed in light of these new findings.…”

“…The ratio of pyrolysable/labile carbon (PC) to TOC decreases significantly with depth and thermal maturity. OM in the shallow samples has the highest PC/TOC ratio (mean = 0.2), while OM in the deep samples has been almost entirely converted to hydrocarbon; the remaining TOC consists of 94 to 98% (mean = 98%) inert carbon(Haeri-Ardakani et al, 2015).…”

Fault and natural fracture control on upward fluid migration: insights from a shale gas play in the St. Lawrence Platform, Canada

11Environmental concerns have been raised with respect to shale gas exploration and production, 12 especially in eastern Canada and northeastern United States. One of the major public concerns 13 has been the contamination of fresh water resources. This paper focuses on the investigation of 14 possible fluid upward migration through structural features in the intermediate zone (IZ), located 15 between a deep shale gas reservoir and shallow aquifers. The approach provides insights into how 16 such an investigation can be done when few data are available at depth. The study area is located 17 in the shale dominated succession of the St. Lawrence Platform (eastern Canada), where the Uti-18 ca Shale was explored for natural gas between 2006 and 2010. Detailed analyses were carried out 19 on both shallow and deep geophysical log datasets providing the structural attributes and prelimi-20 nary estimates of the hydraulic properties of faults and fractures. Results show that the active 21 255 words 29
