Features of Karst Paleogeomorphology and Sedimentary Environment of Ordovician Majiagou Formation in Eastern Ordos Basin [PDF]
ACS OmegaThe formation and evolution of carbonate weathering crust-type reservoirs are closely linked to paleokarst processes. This study aims to restore and analyze the karst paleogeomorphology and sedimentary environment of the Ma2 and Ma3 sections in the eastern Ordos Basin, using the compensation thickness impression method. The Ma3 section is characterized

Controlling Factors of Meteoric Diagenesis in Karst Reservoirs: An Example from the Majiagou Formation, Ordos Basin, China [PDF]
Minerals (Basel, Switzerland), 2023 Karst reservoirs have always been a key field of oil and gas exploration. However, quantifying the process of meteoric transformation remains a persistent challenge that limits the accuracy of reservoir quality prediction. To explore the controlling factors of meteoric cementation on karst reservoirs, the Majiagou Formation of the Ordos Basin in China ...
