摘要： A backpressure valve. The backpressure valve may be configured to maintain a substantially controlled pressure in coiled tubing uphole thereof while simultaneously being compatible with a pressure pulse tool downhole thereof. The backpressure valve includes pressure generating capacity below its internal valve assembly so as to avoid the tendency of the assembly to throttle open and closed. Furthermore, the pressure generation is achieved in a manner avoiding cavitation. As a result, once the backpressure valve is opened, the pressure pulse tool is able to reliably communicate with surface equipment at the oilfield.

摘要： A method and apparatus for internal data conveyance within a well from the surface to a downhole tool or apparatus and for returning downhole tool data to the surface, without necessitating the provision of control cables and other conventional conductors within the well. One embodiment involves sending telemetry elements such as tagged drop balls or a fluid having specific chemical characteristics from surface to a downhole tool as a form of telemetry. The telemetry element or elements are provided with identification and instruction data, which may be in the form of data tags, such as RF tags or a detectable chemical constituent. The downhole tool or apparatus is provided with a detector and microcomputer and is capable of recognizing the telemetry element and communicating with it or carrying out instructions that are provided in the telemetry data thereof.

摘要： A backpressure valve. The backpressure valve may be configured to maintain a substantially controlled pressure in bottom hole assembly while simultaneously being compatible with a pressure pulse tool downhole thereof. The backpressure valve includes pressure generating capacity below its internal valve assembly so as to avoid the tendency of the assembly to throttle open and closed. Furthermore, the pressure generation is achieved in a manner avoiding cavitation. As a result, once the backpressure valve is opened, the pressure pulse tool is able to reliably communicate with surface equipment at the oilfield.

摘要： A perforating gun assembly that includes at least one component that is constructed from a composite material and that is impermeable to wellbore fluids. The components may include the outer carrier and/or loading tube of a perforating gun, the connecting tubing of a gun release mechanism, and the gun connector used to attach adjacent perforating guns. The composite material is designed to be very brittle under dynamic impact. The component is made impermeable to wellbore fluids by including an impermeable liner therein. The impermeable liner can be bonded to the inner or outer surface of the component or can be embedded within the component. Since it is brittle under dynamic impact, the composite component shatters into small pieces upon detonation of the perforating gun.

摘要： An assembly for delivery of treatment fluid at a target location downhole. The assembly is configured to avoid any substantial loss of treatment fluid in advance of reaching the target location in spite of low well pressure or a potentially excessive depth of the location. The assembly also allows for loading with treatment fluid from a downhole end thereof so as to avoid driving treatment fluid through the entirety of a tubular accommodating the assembly. The assembly may employ a spot valve to enhance filling with treatment fluid along with a backpressure valve coupled to the spot valve on-site so as to avoid premature loss of treatment fluid during a delivery application.
