Abstract: A portable system for air separation or air dehydration, or both, is carried on a truck or equivalent vehicle. The air separation system includes, at a minimum, a feed compressor and a gas separation membrane. The air dehydration system includes a feed compressor and an air dehydration membrane. The feed compressor receives power from the engine of the vehicle, only when the vehicle is not moving under its own power. Heat from the vehicle engine may also be used to heat the compressed air stream to prevent the formation of water. The system can also be used to perform air dehydration and air separation simultaneously. The system is substantially self-contained, and can be easily driven from one location to another, simply by driving the vehicle to another location. The invention is especially useful in providing air separation or air dehydration services, or both, for relatively brief periods, at multiple locations.

Abstract: An apparatus and method for breaking up a mixture of gas and liquid forming a foam returning from an oil and/or gas well. The foam breaker includes a housing having a bore for receiving the foam and a restriction in the bore for compressing the foam. A plurality of jets in the restriction are directed into the bore for saturating the foam for breaking up the mixture. The recovered liquid may be filtered and reused.

Abstract: Injecting fluid by inserting a coil tubing having a fluid outlet and a valve above the outlet into a well conduit, biasing the valve to a closed position with a sufficient force to at least balance the hydrostatic force of injection fluid in the tubing, inserting a fluid to be injected in the conduit, and pressurizing the fluid in the coil tubing for opening the valve and injecting the fluid through the fluid outlet. The fluid is ejected in a circumferential direction from the tubing and the tubing may be moved relative to the well conduit while injecting. The upward flow of well fluids in the well conduit may be used to disperse the injected fluid around the interior of the well conduit. The interior of the well conduit may be wiped after injecting the fluid for more evenly spreading the injected fluid. An ejector is connected to the bottom of the coil tubing which initially overbalances the hydrostatic force of the fluid in the coil tubing and opens by injection pressure.
