Claim Text:
1. A one trip perforating and fracturing method for multiple intervals, comprising: in a first interval, isolating an explosives bearing gun from another portion of a borehole with at least one inflatable, by inflating the inflatable at a location adjacent said first interval; boosting wellbore hydrostatic pressure in said gun before firing explosives in said gun with a booster device mounted near said gun before firing explosives in said gun; firing explosives occupying a first space in said gun to initially create perforations in said first interval; flowing a pulse of said boosted pressure from said booster device to pass through said first space previously occupied by said explosives; pumping fluid through said gun through said first space previously occupied by said explosives and into the perforated first interval to fracture said first interval; deflating said inflatable and repositioning said deflated inflatable by at least one other interval; repeating said above steps at least one time by at least a second of said intervals by firing previously unfired explosives occupying a second space, then performing said pumping through said second space.
