Latest Patents
Xiaozhao Cheng holds a patent for "Completions for triggering fracture networks in shale wells." This patent focuses on techniques in horizontal well completions that facilitate multistage fracturing in shale gas reservoirs. The methods involve creating large-scale fracture networks that connect the reservoir and the wellbore by activating pre-existing natural fractures. Additionally, the geo-mechanical characteristics of the formations are analyzed to optimize the maximum stimulated reservoir volumes. The patent also introduces completion optimization patterns for horizontal wellbores, known as altered alternate fracturing completions. These patterns utilize a multi-step combination of simultaneous and alternate fracturing techniques. Furthermore, the dynamic evolution of natural fracture growth is modeled using various criteria, and specific analyses are provided on how well completion patterns influence the fracture network.
