Calculation of vertical fracture extent due to hydraulic fracturing

Calculations to support the vertical fracture extents due to hydraulic fracturing used in the Hydraulic Fracturing node description.\n\n\n## **Attribution** \nGeological and Bioregional Assessment Program\n\n\n## **History** \nKear and Kasperczyk (2020) adapted the approach introduced in Pandurangan et al. (2018) to conservatively estimate the vertical fracture extent across the Cooper GBA region. Propagation of fractures between wells from the same pad completed in the same formation are common and pose a low risk as the wells would be designed and constructed to withstand the imposed fluid pressure from the intersecting hydraulic fracture.

## **摘要**
本数据集由地质与生物区域评估计划（Geological and Bioregional Assessment Program）基于数据集内部及元数据中引用的源数据汇编而成。本数据集同时完成了支撑其水力压裂节点（Hydraulic Fracturing node）描述中水力压裂（hydraulic fracturing）诱发垂直裂缝延伸范围分析的相关计算工作。

## **编制历程**
Kear与Kasperczyk（2020）借鉴Pandurangan等人（2018）提出的研究方法，对库珀GBA区域的垂直裂缝延伸范围开展了保守估算。同一钻井平台上同一地层完钻的井间裂缝传播现象较为普遍，但由于此类井的设计与建造均充分考虑了抵御相交水力压裂所施加流体压力的需求，因此该类风险相对较低。有关裂缝延伸范围计算所用参数及脚本的详细信息，请参阅压缩包内的PDF文档。
