Pore types, genesis, and evolution model of lacustrine oil-prone shale: a case study of the Cretaceous Qingshankou Formation, Songliao Basin, NE China

open access: yesScientific Reports, 2022
A comprehensive characterisation of the pore structure in shale oil reservoirs is essential for forecasting oil production and exploration risks. This study forecasted these risks in the oil-rich Songliao Basin using combination of high-resolution field ...

Shale Permeability under Shale Components’ Thermal Swelling [PDF]

open access: yesGeofluids, 2021
Permeability is one of the most fundamental reservoir rock properties required for modeling hydrocarbon production. However, shale permeability is not yet fully understood because of the high temperature of shale reservoirs. The third thermal stress that is caused by temperature change will decrease the permeability of shale.

A salt-induced viscosifying smart polymer for fracturing inter-salt shale oil reservoirs

open access: yesPetroleum Science, 2019
Inter-salt shale oil reservoirs located between two salt layers are always accompanied by high temperature and high salinity. However, the present commonly used water-soluble polymers in fracturing fluids suffer from poor tolerance to high temperature ...

The Oil Shale Transformation in the Presence of an Acidic BEA Zeolite under Microwave Irradiation [PDF]

open access: yes, 2014
The transformation of an oil shale sample from the Autun Basin in the Massif Central, France, was studied using two different heating strategies: microwave irradiation and conventional heating.

Preservation of molecular fossils in carbonate concretions in cretaceous shales in the songliao basin, northeast China

open access: yesFrontiers in Earth Science, 2023
Paleoenvironmental information is better preserved in carbonate concretions. In this study, carbonate concretions in the Cretaceous Nenjiang shale, Songliao Basin, were examined to determine whether molecular fossils reflective of the paleoenvironment ...

A study of the mechanism of nonuniform production rate in shale gas based on nonradioactive gas tracer technology

open access: yesEnergy Science & Engineering, 2020
The performance of horizontal wells in shale gas is controlled by multiple factors, and there is a difference in gas production rate between different fracturing stages. However, the mechanism of the nonuniform gas production rate is still not clear.

The Charge Quantum Numbers of Gauge Invariant Quasi-free Endomorphisms

open access: yes, 1999
The representations of a group of gauge automorphisms of the canonical commutation or anticommutation relations which appear on the Hilbert spaces of isometries H_\rho implementing quasi-free endomorphisms \rho on Fock space are studied.

Application of High-temperature Methane Adsorption Experiment to Study the Adsorption Capacity of Methane in Shales from the Wufeng Formation, Northeast Sichuan

open access: yesYankuang ceshi, 2020
BACKGROUND Shale methane adsorption capacity is not only a significant parameter to determine the exploration and exploitation plan, but also a critical criterion to evaluate the potential of a shale gas reservoir.
