Abstract
An apparatus for perforating wells has perforating charges and a means for retaining the perforating charges in a first array The first array has a first maximum cross sectional area; and means for expanding the perforating charges into a second three dimensional array The second array has a second maximum cross sectional area larger than the first maximum cross sectional area. Also an apparatus for perforating wells has a plurality of perforating charges and a means for retaining the perforating charges in a first array The first array has a primary axis and a first maximum cross sectional area and the perforating charges having firing directions oriented approximately perpendicular to the primary axis; and means for expanding the perforating charges into a second array, the second array has a second maximum cross sectional area larger than the first.
