Nearly all fra cturing literature attributes the productivity of unconventional reservoir s to the presence of a distributed fracture network within the body of the reservoir. \; The hydraulic fracture is assumed to be the main condui t connecting these natural fractures to each other and to the wellbore.
Based on a rigorous analytical solution, this presentation reviews th e conditions required to activate natural fractures that lie within the bo dy of the formation and away from the propagating hydraulic fracture. &nbs p\;It will show that the most likely cause of the activation of these natu ral fractures is by tensile extension, which occurs when the natural fract ure falls within the influence zone of the tip of the growing hydraulic fr acture.  \;This causes an increase in the effective formation permeabi lity around the main fracture, which ultimately results in increased well productivity. \; This presentation will show that single fractures are more likely to cause natural fracture activation than multiple fractures created in plug and perf \;completions. \; Furthermore, natural fr actures closer to the hydraulic fracture are more likely to become activat ed by it. \; Some of the findings in this presentation differ from com monly-held beliefs in the fracturing community.
