WebDec 14, 2024 · Casing deformation during hydraulic fracturing is a serious problem in Weirong shale gas field. This study investigated the casing deformation mechanism and the influence of fracability on it based on the shale swelling observed in Weirong shale gas field. First, the characteristics of casing deformation wells in different shale gas fields … WebMar 1, 2024 · The fracability level increases with increased content of brittle minerals. The content of quartz was first used to represent shale brittleness, 8 and then dolomite was regarded as another brittle mineral. 9 It was then observed that some silicate minerals such as feldspar and mica are more brittle than clays. However, it has been proved that ...
