Rock physics characterization of shale reservoirs: a case study
Unconventional resources are typically very complex to model, and the production from this type of reservoirs is influenced by such complexity in their microstructure. This microstructure complexity is normally reflected in their geophysical response, and makes them more difficult to interpret. Rock physics play an important role to resolve such complexity by integrating different subsurface di...
متن کاملPorosity and Permeability Analysis on Nanoscale Fib-sem 3d Imaging of Shale Rock
As oil and gas production from conventional reservoirs is declining and oil price is going up, unconventional mudstone reservoirs (“shale-gas”) are becoming more important. However, while their characterization is of utmost importance for production planning, these low permeability rocks are very challenging to characterize due to their complex nano-scale pores and mineral structure. 3D imaging...
متن کاملA new brittleness index for estimation of rock fracture toughness
Assessment of the correlation between rock brittleness and rock fracture toughness has been the subject of extensive research works in the recent years. Unfortunately, the brittleness measurement methods have not yet been standardized, and rock fracture toughness cannot be estimated satisfactorily by the proposed indices. In the present study, statistical analyses are performed on some data col...
متن کاملPetrography, Mineralogy and Geochemistry of Kuhkamar Shale in the Roum section (South of Qayen): Application for Provenance and Tectonic setting
The Kuhkamar shale with a thickness of 354 m is composed of siliciclastic rocks (sandstone and shale). Petrography studies of the sandstones in this area show two petrofacies including arkose and sub-arkose. These sandstones composed of sub rounded to moderately sorted; therefore, compositionaly to texturaly, they are immature to submature with mono and polycrystalline quartz and k-feldespar. I...
متن کاملComment on "A Comprehensive Analysis of Groundwater Quality in The Barnett Shale Region".
The exploration of unconventional shale energy reserves and the extensive use of hydraulic fracturing during well stimulation have raised concerns about the potential effects of unconventional oil and gas extraction (UOG) on the environment. Most accounts of groundwater contamination have focused primarily on the compositional analysis of dissolved gases to address whether UOG activities have h...
