ABSTRACT
This chapter introduces a new design and validation of a new integrated combined fracturability index correlation. Ultralow formation permeability has dictated the creation of a large number of fractures from a single horizontal well. It is not uncommon to design a horizontal well with more than 100 hydraulic fractures transversely intersecting the horizontal well. The large number of fractures is driven by the short exploitation distance resulting from the nanodarcy formation. Fracturing horizontal wells results in the creation of a larger volume of improved reservoir quality. The term SRV is used to describe this improved volume. Mayerhofer et al. discussed the concept of SRV in a recent publication. Methods to manipulate fracturing sequence to enhance fracture complexity and consequently enlarge and enhance the stimulated reservoir volume have been developed by several authors (East et al. 2011). Discussion on the background is found in papers by Soliman et al. (2008), Soliman et al. (2010), and Roussel and Sharma (2011).
