Full-Scale Pore Structure Characterization of the Late Permian Dalong Shale in Western Hubei, Southern China

open access: yesGeofluids
The Late Permian Dalong Formation in western Hubei has recently been recognized as a promising target for shale gas development. However, the comprehensive characterization of its pore structure remains limited. To elucidate the pore system of the Dalong

Effect of Volcanic Activity on Hydrocarbon-Forming Organisms in Organic-Rich Shale: A Case Study of Dalong Formation in Northwestern Sichuan Basin, China

open access: yesFrontiers in Earth Science, 2022
Hydrocarbon-generating material determines the elemental composition and hydrocarbon-generating potential of kerogens in a source rock, and it is the key material basis to control the hydrocarbon-generating capacity of the source rock.

Pore Structure and Fractal Dimension in Marine Mature Silicon-Rich Shale of the Dalong Formation in Western Hubei [PDF]

open access: yesACS Omega
How shale reservoirs and gas contents are affected by the pore structure of shale is very important. Low-temperature nitrogen isothermal adsorption experiments were conducted by us to investigate the pore structure of the Dalong Formation shale. We measured the specific surface area and fractal dimension of the pores and also considered the mineral ...
