Claim 15:
16. A method of detonating an explosive emulsion in a borehole, the method comprising:
lowering a holding device housing an initiator and a shaped charge into a borehole containing an explosive emulsion;
activating the initiator;
initiating the shaped charge in response to activating the initiator; and
detonating the explosive emulsion in response to initiating the shaped charge, wherein the holding device includes:
an initiator holder configured to receive the initiator, the initiator being connected to an electrical cable that extends from the holding device, the initiator holder having a first end, a second end opposite the first end, a longitudinal internal cavity formed within the initiator holder and extending from the first end to the second end, a first longitudinal section, a second longitudinal section, an external surface, and an internal wall that defines the internal cavity;
a top clip positioned on the external surface adjacent the second end of the initiator holder and configured for urging the first longitudinal section and the second longitudinal section radially inward, wherein the internal wall has a portion adjacent the top clip that frictionally retains the electrical cable; and
a shaped charge holder connected to the initiator holder, the shaped charge holder having a plurality of retention fingers extending from the initiator holder and configured for retaining the shaped charge within the holding device.
