Although continuing destructive diagenesis has led to reservoir densification, burial- and facies-dependent dolomitization and dissolution mostly continued in peritidal shoal facies, thus improving the reservoir quality of the dolomites. The findings help targeting deep dolomite gas reservoirs. View chapter...
The first four members of the paraffin series are gaseous and together constitute natural gas: methane, ethane, propane, and n-butane. Peat is a precursor of fossil fuel. Peat occurs in boggy regions and is harvested for fuel and for horticultural use. Peatlands may contain as much as 250...
as the gas composition becomes enriched in heavier components such as ethane and propane, the relative proportion of lost gas unattributed by the canister estimation, would tend to be higher. One advantage of this laboratory protocol is the capability of studying the partially depleted formations; fo...
These species can be killed at early seedling stages (0–4 true leaves) using 20–50 kg/ha propane; at later stages (4–12 leaves) higher rates of 50–200 kg/ha propane, are required (Upadhyaya and Blackshaw, 2007). Predispersal flaming did not affect viability of C. album seeds, it...
[1]for methane alone. Most of these gases escape to the atmosphere during the coalification process but a small fraction is retained in coal. The amount of gas retained in coal depends on a number offactors such as the rank of coal, the depth of burial, the immediate roof and floor to...

(Fig. 1a.3B), δDCH4alone also offers limited analytical distinction between different origins of coalbed gases. However, combinations of both carbon and hydrogen stable isotope ratios of gas components (e.g., methane, ethane, propane, CO2) and chemical gas compositional data greatly enhance the...
The produced gas is first treated to control the dew point. For example, water may be condensed out of the gas in a glycol dehydration unit. The gas is then compressed, metered, and pipelined to a gas plant. Liquids such as condensate, butane, and propane may be recovered at the gas ...
In China, shale gas formations are characterized by old strata, deep burial, high thermal maturity, and multi-stage tectonism (Dai et al., 2014, Zou et al., 2015). Therefore, more targeted criteria are needed to evaluate shale gas generation potential in China. Investigations into the ...
Without passing the pretreating reactor, n-butane that was found to contain an impurity of 0.25% of butenes was converted by 34% (with 62% to iso-butane plus iso-pentane, propane and smaller). In contrast, when the n-butane stream was precontacted with a platinum catalyst at varying ...
