Reconstruction of northeast Asian deformation integrated with western Pacific plate subduction since 200 Ma [PDF]

open access: yes, 2017
The configuration and kinematics of continental deformation and its marginal plate tectonics on the Earth's surface are intrinsic manifestations of plate-mantle coupling.

Identifying thermogenic and microbial methane in deep water Gulf of Mexico Reservoirs [PDF]

open access: yes, 2020
The Gulf of Mexico (GOM) produces 5% of total U.S. dry gas production (USEIA, 2016). Despite this, the proportion of microbial and thermogenic methane in discovered and producing fields from this area is still not well understood.

Novel shape indices for vector landscape pattern analysis [PDF]

open access: yes, 2016
The formation of an anisotropic landscape is influenced by natural and/or human processes, which can then be inferred on the basis of geometric indices.

Optimizing Graphene Oxide Interlayer Spacing for Zeolitic Imidazolate Framework‐8 Growth Toward Enhanced Shale Oil Separation

open access: yesAdvanced Science, Volume 12, Issue 43, November 20, 2025.
Quaternary ammonium salts are used to control the spacing between GO layers, enabling in situ growth of ZIF‐8. The resulting ZIF‐8‐GO membrane exhibits nearly complete rejection of n‐docosane in n‐hexane, solvent permeance of 16.4 ± 0.8 L m−2 h−1 bar−1, and enriches alkanes and aromatics with a molecular weight cut‐off of 310 g mol−1 in shale oil ...

Methane Clumped Isotopes: Progress and Potential for a New Isotopic Tracer [PDF]

open access: yes, 2017
The isotopic composition of methane is of longstanding geochemical interest, with important implications for understanding petroleum systems, atmospheric greenhouse gas concentrations, the global carbon cycle, and life in extreme environments.

Distribution of petroleum enriched areas, Changling Sag, Southern Songliao Basin

open access: yesPetroleum Exploration and Development, 2009
Changling Sag of the southern Songliao Basin is a terrestrial hydrocarbon-rich depression, and according to the “sag-wide oil-bearing theory”, oil and gas can be found in its whole effective source rock area. But prolific oil and gas areas that are usually called “sweet spots” are still controlled by several main factors in distribution.

Diagenetic processes controlled by volcanic detritus of the Lower‐Middle Permian Shanxi and Shihezi sandstone formations, North Ordos Basin, China

open access: yesThe Depositional Record, Volume 11, Issue 5, Page 1645-1668, November 2025.
Comparisons of Lower‐Middle Permian Shanxi and Lower Shihezi formations from the North Ordos Basin reveal that different types and percentages of volcanic detritus induced by active magmatic cycles can significantly change diagenetic evolution and favourable reservoirs.

Guidelines for seismic sedimentologic study in non-marine postrift basins

open access: yesPetroleum Exploration and Development, 2012
This study summarizes the research experiences of non-marine seismic sedimentology in recent years in China and uses Qijia area, Songliao Basin, as a template to establish general guidelines for seismic sedimentology.

Pore Structure Petrophysical Characterization of the Upper Cretaceous Oil Shale from the Songliao Basin (NE China) Using Low-Field NMR

open access: yesJournal of Spectroscopy, 2020
Low-field NMR theory was employed to study the pore structure of the upper cretaceous oil shale, on the basis of fourteen core samples collected from Qingshankou (UCQ) and Nenjiang (UCN) formations in the Songliao basin.
