Abstract

Disclosed embodiments may relate to perforating gun assemblies configured for use in unconventional wells, for example in rock formations with low permeability. In some embodiments, the perforating gun assembly may include a perforating gun housing and at least one shaped charge positioned in the perforating gun housing. The shaped charge and the perforating gun housing may be jointly configured to improve total target penetration in unconventional wells by 20-100%. Related method embodiments may be used to improve the performance of unconventional wells.
