Subjected to the environmental influence of minewater drainage, a new method of minewater deep transfer and storage (MWDTS) was proposed and trialed in the eastern margin of Ordos basin, China. Based on the scientific issue, why, where, how, what and…
The Baode block on the eastern margin of the Ordos Basin is a key area for the development of low-rank coalbed methane (CBM) in China. In order to find out the genesis of CBM and its storage and seepage space in Baode block, the isotopic testing of…
Carbon dioxide (CO2) geological storage (CGS) is an effective way for reducing greenhouse emissions. The injection of CO2 into the deep formation changes the pore pressure and effective stresses in the reservoir, thus leading to changes in…
As the demands of tight-oil Enhanced Oil Recovery (EOR) and the controlling of anthro-pogenic carbon emission have become global challenges, Carbon Capture Utilization and Sequestration (CCUS) has been recognized as an effective solution to resolve…
Carbon dioxide (CO2) geological storage (CGS) is considered as one of the feasible choices for large-scale CO2 emission reduction worldwide, and the primary issue in CGS is how to select areas favorable for storing CO2. The research conducted by…
Based on the study of natural gas resource, low buried hill trap formation mechanism, high quality reservoir control factors and natural gas preservation conditions, the formation conditions and reservoir accumulation characteristics of Bozhong 19-6…
The Ordos Basin is abundant in natural gas resources, and the Shanxi Formation with the transitional facies is considered as a potential stratum for shale gas reservoir. However, the origin and geochemical characteristics of the Shanxi Formation…
The origin and potential source of the presalt natural gas in the Lower Paleozoic Ordovician carbonates within the Ordos Basin, China, is heavily debated, and the causes of carbon isotope reversal are currently unclear. This study analyzes the source…
In order to figure out the accumulation law of tight sandstone gas in the southeastern Ordos Basin and solve the problems in the large-scale benefit productivity construction of Shaanxi Yanchang Petroleum (Group) Co., Ltd., this paper carries out…
The Cambrian weathering crust formed in the Lower Paleozoic central paleouplift of the Ordos Basin and its periphery has always been a key target for oil and gas exploration in this basin, and important breakthroughs in oil and gas exploration have…
The geochemical characteristics of natural gases from Lower Paleozoic Jingbian gas field are abnormal and the carbon isotope of most natural gases has reversed, which led to a dispute over the source of natural gas in the Lower Paleozoic. The Upper…
Low maturity coal samples were taken from the Ordos Basin to conduct gold tube thermal simulation experiment in a closed system, and the characteristics of the products were analyzed to find out the fractionation mechanism of carbon isotopes and the…
Carbon isotopic anomaly occurs in the central gas field of the Ordos Basin (δ13C1 > δ13C2), and natural gas is mainly stored in the Ordovician Majiagou Formation dolomite (OMFD). Inorganic geochemical characteristics of the OMFD, including oxygen,…
Pore structure and connectivity are key factors that determine the quality of tight sandstone reservoirs, which are a frontier field for exploration worldwide in the 21st century but are quite challenging to characterize. Here we explored novel…
The geochemical characteristics of natural gases from Lower Paleozoic Jingbian gas field are abnormal and the carbon isotope of most natural gases has reversed, which led to a dispute over the source of natural gas in the Lower Paleozoic. The Upper…
The chemical and stable isotopic compositions of 24 gas samples were investigated to determine the geochemistry and accumulation process of the Shenmu Gas Field (SGF), Ordos Basin, central China. Natural gas of the SGF includes both wet and dry gas…
