Abstract
Methods and apparatus are provided for conducting multiple successive same-location firings of a number of shaped charges carried by a perforating gun that is lowered into the wellbore and precisely positioned to align its charges with the penetration created by the first fired-charges in order to produce deeper and larger diameter penetrations that result in enhanced hydraulic fracturing of the reservoir and increased gas production from the completed well.
