Indications of the sedimentary environments by the sedimentary characteristics and trace elements of Ordovician Majiagou Formation, Northern Shaanxi salt basin

Geosystem Engineering, 2020
The abundant geochemical information on elements in the autogenous sedimentary rocks can help reconstruct the paleoenvironment of the stratigraphic sedimentation period.

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.

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 ...

Ichnofabrics and their roles in the modification of petrophysical properties: A case study of the Ordovician Majiagou Formation, northwest Henan Province, China

Sedimentary Geology, 2020
Abstract The carbonate rocks of the Ordovician Majiagou Formation from the northwestern part of Henan Province and their diverse trace fossils provide an outcrop analogue for bioturbated, low porosity and low permeability carbonate reservoirs. Three ichnofabrics can be defined based on the ichnotaxonomy, ichnodiversities, individual abundances and ...

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
