Analysis of biomarkers in geological materials such as shales is very crucial because they
can provide useful information on the depositional conditions and environments, organic …

Accurately characterizing the cross-scale structure of pores and fractures in shale reservoirs
is the theoretical basis for efficient exploration and development of shale oil and gas. In this …

The occurrence characteristics of shale oil have a significant impact on its mobility and the
ultimate oil recovery. How to quantitatively characterize the occurrence and distribution …

Abstract The Early Cretaceous palaeoclimate was characterized by arid–humid alternation
and accompanied by a series of short-term extreme environmental events, resulting in …

The imbibition phenomenon widely exists in the fracturing and production process of shale
oil and gas. It is of great scientific and engineering significance to elaborate the mechanism …

Shale oil enrichment and accumulation in lacustrine strata is rather heterogeneous (unlike
that in marine strata), which is a challenging issue to study. Here we carried out a case study …

Low permeability oil reservoirs are characterized by complex pore-throat structure and
complex mechanism of oil and water storage and transmission. At present, the research on …

Tight gas reservoirs are rich in microscale pores and fractures. The effect of microscale gas
seepage in tight sandstone matrix on gas well productivity cannot be ignored. At present, the …

The shale oil and gas resources in the world are rich and are an important part of
unconventional oil and gas resources. In this paper, firstly, by comprehensively using CT …

The distribution pattern of oil and water in different stages of low permeability reservoirs is
one of the main research topics in oilfield development. This paper takes low-permeability …
