Abstract

According to some embodiments, a device, a system, and a method of producing equal entry holes in a wellbore is presented. In some embodiments, at least two shaped charges (10, 12), which each may be configured to produce a different width of perforating jet, may be oriented at different wellbore phasing angles. By selecting the orientation and width of the different perforating jets of the shaped charges across different clearance distances when the perforating gun is decentralized in the wellbore (38), equal entry holes may be formed in the wellbore. For example, a shaped charge with a wider perforating jet may be selected to be oriented across a longer clearance distance, while a shaped charge with a narrower perforating jet may be oriented across a shorter clearance distance. In some embodiments, the at least two shaped charges may use different shaped charge liners with different densities.
