A method and apparatus for acidizing and perforating simultaneously.

Integrated coaxial perforating acidizing operation

Disclosed are thermite charges for use in well perforation and downhole fracing. The thermite charges have a core, and optionally a case, where at least one of the core and the case includes thermite material.

Perforating devices utilizing thermite charges in well perforation and downhole fracing

A loading tube for use in a perforating gun is disclosed which eliminates the necessity for utilization of plastic jackets to restrain shaped charges. The loading tube comprises a first tubular member and an engagement structure in the first tubular member in which the primer ends of the shaped charges may be installed. These engagement structures may be a center plate or inner tubular members. In each of the disclosed embodiments, a detonating cord connects the primer ends of the shaped charges which are installed in the loading tube.

Loading tube for shaped charges

An apparatus for use in a wellbore comprises a heat insulating container having an inner space and having a structure defining a hollow containing a vacuum. The apparatus further comprises a reflective layer arranged on a surface of the heat insulating container to reflect heat for reducing radiated heat originated in the wellbore from reaching the inner space. Also, a signal-activated detonator is provided in the inner space of the heat insulating container.

A weight spacer apparatus has a carrier which is tubular in shape and a spacer tube which is also tubular in shape for insertion into the carrier. The weight spacer apparatus also has a plurality of weight bars which may be inserted into the spacer tube after the spacer tube is inserted into the carrier and which are also removable from the spacer tube. In one embodiment, a weight tray is inserted into the spacer tube for receiving the weight bars, and the weight tray may be fabricated from half-round tubing with a welded plate to cover the diametric opening. In another embodiment, a center plate is attached inside the spacer tube along the length of the spacer tube to divide the spacer tube into first and second compartments.
