Abstract: A cooling system includes a fan chassis housing a fan. A fluid outlet is defined by the fan chassis and located adjacent the fan such that a fluid flow path is defined from the fan, through the fluid outlet, and out of the fan chassis. A filter coupling wall is located in the fan chassis and adjacent to the fluid flow path. A debris filter is located along the filter coupling wall and adjacent to at least a portion of the fluid flow path.

Abstract: A safety cage including two end plates connected by straps extending therebetween is adapted to be placed over an assembled quick connect-disconnect coupling, and the end plates engage behind abutment surfaces on the coupling to prevent accidental separation of the coupling elements. The cage also carries a pair of spaced vertical bars that engage a shoulder on the operating sleeve of the coupling, and lock it against any axial movement. The coupling includes an abutment ring that prevents any forward shifting of the sleeve because of component wear, further eliminating the possibility of accidental separation.

Abstract: The loading station of the invention includes an intake fitting, a pair of pressure operated motorized flow control valves, and a pair of loading boom assemblies that are all mounted on a movable equipment skid. The intake fitting is connectable with a source of high pressure natural gas, and the boom assemblies are universally adjustable and include coupler portions that are connectable with matching coupler portions carried on pressure vessels. Natural gas is loaded into the pressure vessels through the boom assemblies, and the loading station further includes a pressure control system that operates the motorized valves and which prevents natural gas from flowing into the boom assemblies when a pressure vessel is not connected thereto.

Abstract: Natural gas wells in a tight formation area are drilled and completed with piping, the piping being capped with a Christmas tree. The piping is then utilized as a reservoir to collect natural gas from the tight formation over a prolonged time period. Mobile pressure vessel units are employed periodically to recover the collected natural gas, on a schedule designed for maximum economic efficiency. In the preferred embodiment, the reservoir is formed between the inner production tubing and the outer casing tubing, and conduits are connected to direct the natural gas from the production tubing into the reservoir. Liquid/gas separators and dehydrator units are employed on wells as necessary, so that the natural gas stored in the reservoir is ready for transport.

Abstract: A user terminal is provided with two off-loading stations, and at least two separate pressure vessel means are employed to supply natural gas to the user terminal. At least one of the separate pressure vessels is movable to a supply terminal. The off-loading stations are preferably provided with an automatic switchover arrangement to change from one pressure vessel means to another, and the resulting method and system for distributing natural gas assures a continuous supply of natural gas at varying demand rates to the user terminal.

Abstract: Natural gas taken from a gas well is loaded continuously and at a preselected, generally uniform rate into a movable separate pressure vessel means until such is filled with a discrete batch of natural gas at a pressure in excess of 800 psia, whereupon it is replaced with another separate pressure vessel means, with no interruption of gas flow. The filled, movable vessel means is then transported to an off-loading terminal. Well shock is thus controlled, and maximum natural gas recovery obtained. A generally uniform flow rate is obtained by a regulating valve, when well head pressure exceeds about 800 psia, and by a compressor when the well head pressure is below such value.
