Oil production performance in the unconventional reservoirs is significantly affected by the
flooding agent and occurrence environment. In this study, the in-situ stress and …

The occurrence and enrichment of shale plays are highly controlled by pore characteristics
of the formation. In this study, an immature sample rich in kerogen type III from the …

Shale samples with type III kerogen from the Damoguaihe formation were exposed to
hydrous and anhydrous pyrolysis (HP and AHP) in the temperature range of 300–450° C …

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 …

The movable fluid porosity can be used as a sensitivity factor to reflect the seepage capacity
of tight reservoirs. However, the stress sensitivity and compressibility of samples differ and it …

Natural fractures are of paramount importance in storing carbon in shale oil reservoirs,
where ultra-low porosity and permeability necessitate their essentiality for enhanced oil …

Coalbed methane (CBM) exploration and development is becoming increasingly complex,
and the deterioration of resource quality is intensifying. In this paper, first, based on the …

Shale reservoirs are rich in micro and nanoscale pores and fractures, resulting in a very
complex interaction mechanism between oil and water. In this paper, firstly, the differences …

Low permeability and tight oil reservoirs are rich in microscale pores and contain a large
amount of dissolved gas. With the progress of production, the volatile gas gradually forms a …

The characteristics of bedding development have an important impact on the spatial
distribution of shale pores and fractures. However, there is a lack of systematic study on the …
