Abstract: A buffering device for use in conjunction with a downhole tool string, wherein the tool string includes a ballistics device. The buffering device includes a mandrel attached within a tool string and proximate to the ballistics device. An anchor is disposed on the mandrel and a disk plate is coaxially placed on the mandrel that is slideable thereon. The disk plate is proximate to the ballistic device. A resilient member, such as a spring, is coaxially placed on the mandrel between the disk plate and the anchor. The pressure wave produced by activation of the ballistic device pushes the disk plate toward the anchor and compresses the spring there between. Since the disk plate extends outward into sealing contact with casing lining the wellbore, compression of the spring dissipates energy waves produced by activation of the ballistic device.

Abstract: A lock for a perforating gun system comprising, a housing, a cylinder formed in the housing, a piston assembly disposed within the cylinder, and anchoring arms coupled with the piston assembly. Detonation of the shaped charges of an associated perforating gun produces a pressure surge which is communicated to a surface of the piston assembly. Appropriate movement of the piston assembly outwardly rotates the anchoring arms into anchoring engagement with an associated tubular. Thus the pressure from the detonation event will anchor a perforating system within its associated tubular.

Abstract: A modular wellbore treatment system having a reservoir for holding wellbore/reservoir treatment material, a pump for pressurizing and delivering the wellbore/reservoir treatment fluid, and a sealing section for creating a localized pressurized zone proximate to a region of a formation to be treated. The wellbore treatment fluid includes permeability modifiers, gel, acids, stimulation fluids, epoxy type substances, void fillers, gravel pack fixing compounds, brine, reactive fluids to water, oil, and gas, and alcohol.

Abstract: A perforating system and method for wellbore perforating. The system comprises a perforating string having a perforating gun with shaped charges, a communication module for receiving detonation signals, and a controller associated with each perforating gun. The module receives surface signals for gun detonation and wirelessly transmits the signals to selected guns via the associated controllers.

Abstract: A communication module for use in wellbore logging operations. The module is attachable around a wireline, slickline, tubing or coiled tubing having a logging tool on its end. The module includes a drive means for transporting it down the line, a controller for controlling its operation, and communications for communicating with the logging tool. Communication between the module and the logging tool includes the transfer of data and operational instructions.
