Abstract
A non-detonable shaped charge capable of becoming detonable upon activation. The shaped charge may be utilized for use with a perforating gun in oilfield applications. In this regard, during transport and other handling in advance of reaching the application site, the charge may be non-detonable. However, upon an intentionally directed activation, such as through heating, the shaped charge may be detonable.
Claims11
A method of perforating a well at an oilfield, the method comprising:
- loading a shaped charge into a perforating gun in a non-detonable state;
- advancing the perforating gun to a target location in the well;
- activating the shaped charge to a detonable state;
- and
- perforating the well at the target location with the detonable shaped charge;
- wherein the activating comprises:
- heating the shaped charge;
- and
- applying a targeted movement to the shaped charge by pivotally extending the shaped charge away from a housing of the perforating gun with a carrier thereof.
6 more elements
A shaped charge system for perforating a well at an oilfield, the system comprising:
- a perforating gun;
- a conveyance coupled to the gun for advancement thereof into the well;
- a shaped charge secured within the gun, the charge housing oxidizer and fuel components in a non-detonable state relative one another in advance of activation thereof into at least a partially liquid mixture thereof, wherein the perforating gun comprises a carrier for the securing of the shaped charge, the carrier pivotable to introduce a targeted movement to the charge for the activation.
