Optimal Selection of Favorable Areas for CO2 Geological Storage in the Majiagou Formation in the Ordos Basin

International Journal of Greenhouse Gas Control, 2021
<p>CO<sub>2</sub> geological storage (CGS) technology is currently one of the best choices for large-scale low-cost CO<sub>2</sub> emission reduction in the world, and the primary issue of CO<sub>2</sub> geological storage is the optimization of the ...

Diagenetic differentiation in the Ordovician Majiagou Formation, Ordos Basin, China: Facies, geochemical and reservoir heterogeneity constraints

Journal of Petroleum Science and Engineering, 2020
Abstract Diagenesis is a key process that affects carbonate reservoir formation and evolution. This paper presents a detailed study of a carbonate shoal reservoir in the Ordovician Majiagou Formation, Ordos Basin, China. This reservoir records different diagenetic features that are related to reservoir heterogeneity.

Characteristics of Karstification in the Penecontemporaneous Period in Majiagou Formation, Ordovician, Sulige Gas Field

2021
Sulige gas field is the major gas-production area in Ordos Basin. The carbonate of the Ordovician Majiagou formation is one of the most important target-strata for gas exploration. The karstification in the penecontemporaneous period has a significant constructive effect on the reservoir development of Majiagou formation, which is the most important ...

Petrographic, rare earth elements and isotope constraints on the dolomite origin of Ordovician Majiagou Formation (Jizhong Depression, North China)

Marine and Petroleum Geology, 2020
Abstract Dolomites from the Ordovician Majiagou Formation are considered as major hydrocarbon reservoir rocks in the Yangshuiwu area, Jizhong Depression. However, the origin of the dolomites remains unclear. This study utilizes a composite analysis of seawater-normalized rare earth elements (REEs), petrography and isotopes (C, O and Sr) to trace ...

The genesis and significance of pyrite in the Ordovician Majiagou Formation in the central and eastern Ordos Basin

Petroleum Geoscience
The geochemical data of the gas sourced from the Majiagou Formation indicate low organic content and high thermal maturity, which make the evaluation of the hydrocarbon generative potential difficult. However, the low organic abundance and high thermal maturity of the Majiagou Formation make it difficult to evaluate its hydrocarbon ...

The lithology and reservoir properties of the Lower Ordovician Majiagou formation at the Tabamiao gas field (Ordos Basin, China)

Moscow University Geology Bulletin, 2016
The Ordos Basin is known for rich natural gas, coal, and oil fields; it is an important mineral raw material and electric power base of China. Among the recently discovered gas fields within the Yimeng Monocline, the Sulige and Tabamiao gas fields, where gas reserves are found in Lower Ordovician carbonate rocks, are best known. We have identified five
