Research and Optimization of Gas Extraction by Crossing-Seam Boreholes from Floor Roadway by Gang Li, Jiafei Teng

“…The results show that the gas extraction effect by ordinary drilling boreholes is lower than that of the punching combined drilling boreholes, and the extraction is uneven and makes it difficult to meet the standard. Hydraulic punching was carried out, and coal was washed out of the borehole, which expanded the contact area between the borehole wall and coal seam. …”

Numerical Simulation on Hydrofracture Propagation in Fractured-Vuggy Unconventional Reservoirs by Tingxue Jiang, Haitao Wang, Xiaobing Bian, Daobing Wang, Jun Zhou, Bo Yu

“…Acid fracturing of carbonate reservoir is completed through the complex mechanical mechanism of interaction between vug and hydraulic fracture (HF). We use the equivalent method of reducing the rock strength by acid etching and serious fluid leakoff during interaction of HF and vug to establish a finite element (FE) model of HF propagation during acid fracturing in the fractured-vuggy carbonate reservoir. …”
