Quantitative Analysis of the Formation and Evolution of Underpressure in Tight Sandstone Reservoirs in the Craton Basin: The Chang 7 Member in the A Area of the Ordos Basin Open
The Ordos Basin is a typical craton basin. Underpressure exists in the tight sandstone reservoirs of the Chang 7 member of the Upper Triassic Yanchang Formation in the Yishan slope of the basin. However, overpressure was verified in these …

Shale oil resource evaluation with an improved understanding of free hydrocarbons: Insights from three-step hydrocarbon thermal desorption Open
The pyrolysis parameter S1, which indicates the amount of free hydrocarbons present in shale, is often underestimated due to hydrocarbon loss during sample handling and measurement processes. To remedy this issue, we strongly recommend an …
