Fluid–Solid Coupling Simulation and Field Flow Response of Separate-Layer Fracturing in Vertically Heterogeneous Thick Shale: Insights from the Qiongzhusi Formation

Fluids
The Qiongzhusi Formation, a thick and vertically heterogeneous marine shale sequence in southern China, presents substantial obstacles to efficient hydraulic stimulation when conventional horizontal-well staged fracturing is applied, owing to marked ...

Pre-stack seismic density inversion in marine shale reservoirs in the southern Jiaoshiba area, Sichuan Basin, China

Petroleum Science, 2018
For a typical marine shale reservoir in the Jiaoshiba area, Sichuan Basin of China, P-impedance is sensitive for identifying lithology but not suitable for indicating good shale reservoirs.

Shale Gas Research For Europe

, 2012
Several projects initiated and coordinated by the Helmholtz Centre Potsdam ‐ GFZ German Research Centre for Geosciences focus on shale gas and may serve as entry points for the understanding of general features for efficient shale-gas production, not only in Europe.

Modeling and monitoring injectivity evolution during cold CO2 injection with field evidence from aquistore carbon capture and storage operations

Deep Underground Science and Engineering, EarlyView.
This work integrates 5 years of field data from the Aquistore CCS project with a non‐isothermal THM modeling framework to explain how cold CO2 injection alters injectivity over time. The study shows that sustained cooling near the wellbore reduces effective stresses, promotes tensile micro‑cracking, and leads to semi‑reversible permeability enhancement

Safety Evaluation Method for Casing Running in Deep Shale Gas Horizontal Wells

Shiyou jixie
To address issues such as passability and pre-fracturing casing deformation during casing running operation in deep shale gas wells， the beam-column infinitesimal method was used to build a mechanical model for trajectory of casing running in crooked ...

China Stakes on Shale Gas

, 2016
The shale gas production in the USA was not missed in China for which the issues of hydrocarbon export and development of own resources are always in the focus of attention of its leadership. Preliminary investigations conducted in China have revealed considerable reserves of shale gas.

Production of Shale Oil

, 1982
Intensive pre-project feasibility and engineering studies begun in 1979 have produced an outline plan for development of a major project for production of shale oil from private lands in the Piceance Basin in western Colorado.

Reusing depleted oil and gas wells for geothermal energy: Feasibility, challenges, and a decision‐making framework for sustainable conversion

Deep Underground Science and Engineering, EarlyView.
The graphical abstract presents a structured decision‐support framework for assessing the feasibility of converting depleted oil and gas wells into geothermal energy systems. The left panel illustrates a comprehensive, multi‐stage decision‐making framework progressing from prefeasibility screening and technical–economic analysis to policy alignment ...

Shale Gas The Promise and the Peril [PDF]

, 2012
Shale gas has the potential to transform the U.S. energy-based economy in the electricity, transportation, and chemical sectors. U.S. success can be expected to translate to Europe and other parts of the world. Shale gas production is uniquely enabled by hydraulic fracturing, a technique that has come under heavy scrutiny for its potential to cause ...
