Abstract: A repositionable attenuator for a terminal unit in a heating, ventilation, and air conditioning system is disclosed. The attenuator is positionable between at least a first and a second position. This enables the attenuator to be attached to and shipped with the terminal unit prior to installation of the terminal unit.

Abstract: The present invention relates to down structure injected water drive pressure WDP into crude oil, or natural gas formations. In oil formations, for maintaining pressure up structure on in place oil above its existing bubble point, during its recovery. And for miscible gas injection, where strategically located gas injection wells inject miscible gas into oil formations, to enter into solution with in place oil at optimum injection pressure, adding solution gas saturation and pressure, to increase its mobility and fluidity. And for producing solution gas saturated oil and any condensate, into the invention's recovery well's controlled lower wellbore pressure, still above existing bubble point pressure, where these liquid hydrocarbons are pressure injected through the invention's extended float system EFS Liquid Injector DOLI, into the lower pressure tubing, while preventing entry of gas, for total in place oil recovery.
