MATERIAL BALANCE EQUATION OF OVERMATURE ORGANIC-RICH GAS SHALE

Organic compounds in produced waters from shale gas wells.

A detailed analysis is reported of the organic composition of produced water samples from typical shale gas wells in the Marcellus (PA), Eagle Ford (TX), and Barnett (NM) formations. The quality of shale gas produced (and frac flowback) waters is a current environmental concern and disposal problem for producers. Re-use of produced water for hydraulic fracturing is being encouraged; however, kn...

Shale gas and hydrofracturing.

About the Cover: Black carbon (BC) containing particles have an important role to play in climate change; directly heating through absorption of radiation, and/or indirectly cooling through the seeding of clouds. New research in this issue, using a mobile laboratory indicates that gasoline powered cars may produce more BC than previously considered. Transmission electron microscopy background i...

Methodology of organic-rich shale lithofacies identification and prediction: A case study from Marcellus Shale in the Appalachian basin

The success of shale gas in North America has attracted increased interest in “unconventional” reservoirs. Two critical factors for shale-gas reservoirs are units amenable to hydrologic fracture stimulation and sufficient natural gas content. The effectiveness of hydrologic fracture stimulation is influenced by rock geomechanical properties, which are related to rock mineralogy. The natural gas...
