History

Kear 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. Refer to the PDF document in the zip file for details of the parameters and script used to calculate the fracture extent.
