Micropore structure and fractal characteristics of shale in Midwest China

Journal of Petroleum Exploration and Production Technology
To further clarify the optimal target layer in the horizontal section of Wufeng–Longmaxi shale, we selected 126 shale samples from the Wufeng–Longmaxi Formations (Long11 1 to Long11 4 and Long12 submember) as the primary study objects from the ...

Using nanoindentation to quantify the mechanical profile of the Wufeng–Longmaxi Formation in southwestern China: link to sedimentary conditions

Solid Earth
Abstract. The fine construction of a continuous mechanical profile for the Wufeng–Longmaxi (WF-LMX) Formation is crucial for designing hydraulic fracturing projects in shale gas development, which however is generally difficult to achieve by conventional macroscopic mechanical testing methods due to the difficulty in obtaining continuous block shale ...
