A protection barrier system for energy-absorption of impacts includes an elongated barrier defining a chamber therein. The barrier includes side walls having a plurality of connected non-vertical wall segments and a plurality of buttresses positioned vertically at spaced apart locations along each side wall. One or more guide channels are positioned on each side wall in horizontal alignment with similar guide channels on like-configured barriers. A coupling is disposed on each opposed end of the barrier for coupling of either barrier end juxtaposed in end-to-end nested arrangement with like barriers. A supplemental energy-absorbing system is connectable between opposed ends of end-to-end coupled barriers, providing energy-absorbing tubes removably inserted through each guide channel of each barrier. Cables are extendable through the tubes in the guide channels of the nested barriers, providing additional energy-absorption and deterrence from breaching of the barriers. A method of manufacture for the protection barrier is also disclosed.

The nozzle may include orifices for discharging fluid to drive the nozzle forward and includes a disk or other device having orifices to produce a swirling motion to fluid in the body of the nozzle. Swirling fluid is discharged from a front orifice and an extension is placed forward of the front orifice to confine the swirling fluid in a radial direction. ning a natural gas well bore, the apparatus comprising: a vehicle providing in combination: a master valve for capping the well bore, the master valve supporting a blowout preventor and an injector head mounted thereon; the master valve interconnected with a pressure vessel through a vessel control valve; the pressure vessel interconnected with a compressor and with an outgoing gas pipeline through control valves; the compressor providing compressed natural gas from the pressure vessel to the well bore through the injector, head and the master valve through a tubing taken from a tubing reel and then inserted into the well bore. 2. The apparatus of claim 1 further comprising a bypass line from the master valve to the pipeline. 3. The apparatus of claim 2 further comprising a check valve and a pipeline valve in a line between the pressure vessel and the pipline. 4. A method for cleaning a natural gas well bore, the method comprising the steps of: moving a vehicle mounted equipment having a compressor, pressure vessel and reel of tubing to a well site; capping a well bore with a master valve having a blowout preventor and injector head mounted thereon; interconnecting the master valve with a pressure vessel through a vessel control valve, interconnecting the pressure vessel with the compressor and with a outgoing gas pipeline through control valves respectively; providing compressed natural gas from the pressure vessel to the well bore through the compressor, injector head and the master valve with a tubing reel inserted into the well bore. 5. The method of claim 4 further comprising the step of providing a bypass line from the master valve to the pipeline. 6. The method of claim 5 further comprising the step of providing a check valve and a further control valve in a line between the pressure vessel and the pipline. 7. A method for cleaning a natural gas well bore, the method comprising the steps of: moving a vehicle to a well site, the vehicle providing a compressor joined with a pressure vessel and a tubing reel with coiled tubing; capping a well bore with a master valve having a blowout preventor and an injector head mounted thereon; interconnecting the master valve with a pressure vessel through a vessel control valve; interconnecting the pressure vessel with a compressor and with an outgoing pipeline through further control valves; providing a bypass line from the master valve to the pipeline and providing a check valve and a control valve in a line between the pressure vessel and the pipline; introducing the coiled tubing into the injector head and with the master valve open inserting the coiled tubing into the well bore; closing the blowout preventor to cause a seal around the coiled tubing; extracting natural gas from the well bore into the pressure vessel; compressing the extracted natural gas taken from the pressure vessel; injecting the compressed natural gas into the well bore; extracting well bore clogging materials from the well bore and into the pressure vessel; withdrawing the coiled tubing into the blowout preventor; closing the master valve; and compressing any remaining natural gas and delivering said gas to the pipeline. s Reporter, pp. 71 & 73, Oct. 2001.
