“…While Ballentine and Sherwood Lollar (2002) stated that gases with 4 He > 0.1% nearly always contain high nitrogen contents, the Australian natural gases generally show a weak positive correlation between 4 He and nitrogen and poor correlation within individual basins (Fig. 11), which does not support an overall strong correspondence between nitrogen and crustal, radiogenic helium nor the concept for a dominant deep metasedimentary or crystalline origin for the associated nitrogen (Jenden et al 1988a(Jenden et al , 1988b. Additionally, the stronger positive linear correlation between R/Ra and 3 He/N 2 (Fig.…”

Helium in the Australian liquefied natural gas economy

Australia is about to become the premier global exporter of liquefied natural gas (LNG), bringing increased opportunities for helium extraction. Processing of natural gas to LNG necessitates the exclusion and disposal of non-hydrocarbon components, principally carbon dioxide and nitrogen. Minor to trace hydrogen, helium and higher noble gases in the LNG feed-in gas become concentrated with nitrogen in the non-condensable LNG tail gas. Helium is commercially extracted worldwide from this LNG tail gas. Australia has one helium plant in Darwin where gas (containing 0.1% He) from the Bayu-Undan accumulation in the Bonaparte Basin is processed for LNG and the tail gas, enriched in helium (3%), is the feedstock for helium extraction. With current and proposed LNG facilities across Australia, it is timely to determine whether the development of other accumulations offers similar potential. Geoscience Australia has obtained helium contents in ~800 Australian natural gases covering all hydrocarbon-producing sedimentary basins. Additionally, the origin of helium has been investigated using the integration of helium, neon and argon isotopes, as well as the stable carbon (13C/12C) isotopes of carbon dioxide and hydrocarbon gases and isotopes (15N/14N) of nitrogen. With no apparent loss of helium and nitrogen throughout the LNG industrial process, together with the estimated remaining resources of gas accumulations, a helium volumetric seriatim results in the Greater Sunrise (Bonaparte Basin) > Ichthys (Browse Basin) > Goodwyn–North Rankin (Northern Carnarvon Basin) accumulations having considerably more untapped economic value in helium extraction than the commercial Bayu-Undan LNG development.

Because the middle tectonostratigraphic section in the Xuanhan-Daxian region has experienced intensive faulting and folding, the deep seated faults may have provided conduits for fluid migration from several source rocks in different formations, and thus make it possible for multiple source rocks to charge the Feixianguan-Changxing reservoirs in the Puguang and Maoba fields.…”

Northeastern Sichuan Basin is one of the most significant areas for natural gas exploration in China, and Puguang and Maoba are the two most important and typical gas fields there. The common characteristics of the natural gases in the Puguang and Maoba gas fields include extremely high dryness, high H 2 S contents, high δ 13C 1 values, with a wide range of δ 13 C 2 values. Based on gas composition and stable carbon isotope values, natural gases in the study area are classified into three genetic groups, derived from type III kerogen, type II kerogen and those with a complex origin. The latter group is most likely the result of mixing between low maturity ethane inherited from earlier oil accumulation and high maturity methane generated from subsequent in-reservoir oil cracking and thermochemical sulfate reduction. In conjunction with regional source rock data, the Upper Permian Longtan Formation is considered to be the main source rock for the gases in the Feixianguan-Changxing reservoirs of the Puguang and Maoba gas fields.

“…It plays an important role in the process of oil/gas generation. Meanwhile, the information about the hydrogen isotopic composition of natural gas is of specific significance [1][2][3][4][5][6], and hydrogen isotopic analysis is one of the most important approaches to studying the process of hydrocarbon generation, the variation trend following hydrocarbon generation, and oil/gas-source correlation [7][8][9][10][11][12][13]. Unsophisticated H isotope analytical technology has long hampered the study and development of hydrogen isotope geochemistry.…”

The influences of water media on the hydrogen isotopic composition of organic-thermogenic natural gas were tested in three series of experiments on coal pyrolysis, with no water, deionized water (δD H 2 O =−58‰), and seawater (δD H 2 O =−4.8‰) added, respectively. The experimental results show that the productivities of H 2 and CO 2 obviously increased under hydrous conditions and that the productivity of CH 4 also remarkably increased in the high-evolution phase of hydrous experiments. Water was involved in the chemical reaction of hydrocarbon generation, and then the hydrogen isotopic composition of methane was affected. There is a linear correlation between the hydrogen isotopic composition of methane and its productivity, as reflected in the three series of experiments. In the case of the same CH 4 productivity, the hydrogen isotopic composition of the methane produced in anhydrous experiments was the heaviest, that of the methane produced in seawater-adding experiments came second, and that of the methane produced in deionized water-adding experiments was the lightest. The hydrogen isotopic composition of natural gas/methane is affected by the following factors: 1) the characteristics of hydrogen isotopic composition of organic matter in source rocks, 2) the thermal evolution extent of organic matter, and 3) fossil-water media in the natural gas-generation period. The experimental results show that the influence of the fossil-water medium in the natural gas-generation period was lower than that of the other factors.water medium, natural gas, hydrogen isotopic composition, pyrolytic simulation experiment Citation:Wang X F, Liu W H, Xu Y C, et al.
