A Method for Predicting Different Types of Natural Fractures in Tight Sandstone Based on the Secondary Rescaled Range Analysis of Logging Curves: A Case Study From the Chang 7 Member in Huaqing Oilfield, Ordos Basin, China

open access: yesEnergy Science &Engineering, Volume 13, Issue 4, Page 2045-2062, April 2025.
Flowchart of prediction method for natural fractures based on the secondary rescaled range analysis. ABSTRACT Currently, there are various methods for predicting natural fractures using logging data, however these methods are primarily for predicting the number and location of fractures. This is making it difficult to determine fracture types.

Multi‐Objective Optimization of the Food‐Energy‐Water Nexus Problem: A Review of the Key Concepts and Emerging Opportunities in Objective Functions, Decision Variables, and Optimization Techniques

open access: yesEarth's Future, Volume 13, Issue 4, April 2025.
Abstract Food, energy, and water are basic needs that are quite important in livelihood sustainability. In most situations, their interactions make trade‐offs between these key areas of need challenging to attain. For the Food‐Energy‐Water Nexus (FEWN), there exists a need for appropriate decision‐making tools that may help to surmount such challenges.

Thrusting and exhumation of the southern Mongolian Plateau: Joint thermochronological constraints from the Langshan Mountains, western Inner Mongolia, China [PDF]

open access: yes, 2017
The Mongolian Plateau has undergone multi-stage denudation since the Late Triassic, and the NE-trending Langshan Mountains in the southern margin of the Mongolian Plateau is crucial to unraveling the Meso-Cenozoic cooling and exhumation history of the ...

Tracing the Contribution of Abiotic Methane in Deep Natural Gases From the Songliao Basin, China Using Bulk Isotopes and Methane Clumped Isotopologue 12CH2D2

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.
Abstract The identification and evaluation of abiotic methane remain an active research area due to uncertainties in traditional indicators that may lead to “false‐positive” detections. As an emerging isotopic tool, methane clumped isotope can provide novel information about the generation and post‐generation processes of methane gases.

Paleogeomorphy evolution of the Ordovician weathering crust and its implication for reservoir development, eastern Ordos Basin

open access: yesPetroleum Research, 2018
Gas reservoir development of the Ordovician weathering crust in the Ordos Basin is closely controlled by the pre-Carboniferous paleogeomorphy. Previous studies show that the paleogeomorphy is high in the west and low in the east, and the karst highland ...

Deep‐Circulating Groundwater From the Tibetan Plateau Constructed the Loess Plateau

open access: yesGeophysical Research Letters, Volume 52, Issue 5, 16 March 2025.
Abstract China's Loess Plateau (LP) is a quintessential example of a desert transitional environment characterized by a distinctive soil profile comprising of a red clay layer overlain by loess. The source of the sedimentary materials that formed the plateau, as well as the mechanism for the red clay/loess transition, are yet unexplained.

Significance of three reservoir profiles for the risk exploration in Ordos Basin

open access: yesPetroleum Exploration and Development, 2011
The Ordos Basin went through six main stages of geological evolution, developed three sets of soure rocks, two unconformities, several sets of reservoirs and caprocks, and had three typical petroleum systems, i.e. Lower Paleozoic Ordovician gas reservoirs, Upper Paleozoic Carboniferous-Permian gas reservoirs, and Mesozoic Triassic-Jurassic oil ...
