Abstract: A perforating system having a perforating gun with a gun body formed from a ductile material. The gun body deforms under pressure while maintaining sufficient structural integrity to remain intact and without rupturing or leaking. A flowable material can be inserted within the gun body that provides additional support to the gun body.

Abstract: A method for estimating a property of an earth formation, the method includes: conveying a carrier through a borehole penetrating the earth formation; irradiating the formation with neutrons from a neutron source disposed at the carrier; detecting a first signal from the formation due to the irradiating using a first radiation detector, the first signal being related to a saturation of a fluid in the formation; detecting a second signal from an element in the formation due to the irradiating using a second radiation detector, the second signal being related to an element emitting the second signal in the formation; and estimating the property from the first signal and the second signal.

Abstract: A perforating system having a perforating gun with a high pressure gun body. The gun body can be thickened so that no empty space is present between it and a corresponding gun tube. Alternatively, the gun body could be a solid cylinder with slots radially formed therein to receive a shaped charge. In another embodiment, a flowable material, such as foam, fluid, sand, ceramic beads, eutectic metal, and combinations thereof, is provided in the space between the gun body and gun tube.

Abstract: An initiator for initiating detonation in a detonation cord of a perforating system, where the initiator comprises a modular electronic igniter that quick connects into a portion of high explosive. The high explosive is disposed in a housing having an end of detonation cord crimped therein. The electronic igniter may be shipped to the field and/or stored separate from the high explosive then the two may be assembled just prior to deploying the perforating gun assembly in a wellbore. Various methods of quick connecting the electronic igniter to the high explosive may be used.

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.

Abstract: A method and system for cementing and perforating a wellbore in a single step by coupling a perforating gun with a wiper plug. The method includes injecting cement in a wellbore having casing therein and an annulus between the casing and wellbore. A wiper plug is dropped on the cement having a perforating gun attached to the wiper plug. The plug is forced downward pulling the perforating gun along. The downward motion of the plug in turn pushes the cement out the bottom end of the casing and into the annulus. The cement in the annulus is allowed to set and the perforating gun is activated.

Abstract: A method of perforating a wellbore by forming a perforation that is aligned with a reservoir characteristic, such as direction of maximum stress, lines of constant formation properties, and the formation dip. The wellbore can be perforated using a perforating system employing a shaped charge, a mechanical device, or a high pressure fluid. The perforating system can be aligned by asymmetric weights, a motor, or manipulation from the wellbore surface.

Abstract: A method of completing a wellbore that includes providing wellbore casing having shaped charges and permanent pressure gauges on an outer surface of the casing. In an example of use, the casing is inserted into the wellbore and cement is injected into an annulus formed between the casing and wellbore. The shaped charges are strategically deployed on the casing so they aim towards a wall of the wellbore and are spaced apart along the casing. Thus detonating the shaped charges creates perforations into a formation around the wellbore and places the pressure gauges into pressure communication with the formation. Pressure readings are delivered to the surface from the pressure gauges in the form of signals.

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 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 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 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.
