Abstract: Safety apparatus is disclosed for providing ballistic train interruption in a perforating system. The safety apparatus comprises a generally tubular shaped housing having first and second ends which are fabricated to permit the housing to be positioned at any location in the perforating system. The apparatus comprises first and second ballistic sections in the housing and a third ballistic section which is rotatably mounted in the housing to move between a disarmed position and an armed position based on downhole pressure. Upon retrieval of the perforating system from the wellbore, the safety apparatus functions to return a third ballistic section to its disarmed position. Additionally, apparatus is provided to permanently disable the third ballistic section to insure that no inadvertent detonation of the guns occurs when retrieving the system from a wellbore.

Abstract: A system that is usable with a well includes tubular body, at least one perforating charge that is disposed on the tubular body and at least one screen section that is disposed on the tubular body. The perforating charge(s) and the screen sectional(s) are adapted to be run downhole in a single trip into the well with the tubular body.

Abstract: A technique to install a tool in a well includes running the tool into the well and fixing the tool to the well with a fixing agent without pumping the fixing agent through a central passageway of the tool. The tool may be a perforating gun that includes a casing body that includes a longitudinal axis. The perforating gun may also include a fin and a perforating charge. The fin radially extends from the casing body, and the perforating charge is attached to the fin and is oriented to generate a perforation jet in a radial direction away from the longitudinal axis of the casing body.

Abstract: A release tool and method of use for releasing tools (such as perforating guns) from tool strings (such as perforating strings) after use in well bore operations. It is emphasized that this abstract is provided to comply with the rules requiring an abstract, which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Abstract: A technique that is usable with a well includes running a production string into the well so that the production string extends through a first isolated zone of the well and at least into a second isolated zone that is located farther into the well than the first isolated zone. The production string includes integrated perforating charges. The technique also includes firing the perforating charges inside the first zone; and after the firing, maintaining fluid isolation between the first isolated zone and a passageway of the production string. The passageway communicates well fluid from the second isolated zone.
