Abstract Chlorite, an Fe-and Mg-rich aluminosilicate clay, may be either detrital or authigenic
in sandstones. Detrital chlorite includes mineral grains, components of lithic grain, matrix …

The genetic identification of different types of natural gas is notably important for assessment
of its sources and exploration potential. The chemical and isotopic (C and H, in particular) …

四川盆地海相层系发现的大气藏都含或高含硫化氢, 都发育一定厚度的优质储层,
而且优质储层与硫化氢分布具有密切的关系, 即气藏硫化氢含量越高, 储层性质越好 …

Biomarkers are compounds found in crude oil with structures inherited from once-living
organisms. They persist in oil spills, refinery products and archaeological artifacts, and can …

The association of dissolved sulfate and hydrocarbons is thermodynamically unstable in
virtually all diagenetic environments. Hence, redox-reactions occur, whereby sulfate is …

Bacterial and thermochemical sulfate reduction apparently occur in two mutually exclusive
thermal regimes, ie, low-temperature diagenetic environments with 0< T< 60–80° C and …

Petroleum deposits form as a consequence of the increased temperatures that accompany
progressive burial of organic matter deep within sedimentary basins. Recent advances in …

The second edition of The Biomarker Guide is a fully updated and expanded version of this
essential reference. Now in two volumes, it provides a comprehensive account of the role …

The porosity and permeability of sandstone and carbonate reservoirs (known as reservoir
quality) are essential inputs for successful oil and gas resource exploration and exploitation …

四川盆地川东北地区是中国含油气盆地中已发现的高含硫化氢天然气储量最大的地区.
