Superheated steam from a generator () proximate a well () is delivered through an output pipe () that communicates through a dual entry wellhead () with downhole steam piping () extending into the well (). Steam is delivered at approximatelyPSIG over the frictional and other losses encountered from the surface to the steam piping outlet (). Oil is extracted through production tubing () passing through wellhead (). Production tubing () and steam delivery piping () are secured in parallel relationship by clamps (). The production tubing () communicates with a lift pump, and the steam piping () is terminated generally at a midpoint of the production tubing (), several feet above the lift pump. A thermocouple () is placed approximately two feet below the end of the steam piping ().

Method and apparatus for the downhole injection of superheated steam

Modularized, superheated steam generators comprise a steam module (), a thermocouple module (), and an electrode module () assembled within a containment enclosure (). The multi-stage steam module () comprises a plurality of first stage pressure vessels () surrounding and feeding a second stage pressure vessel (). The steam module () is coaxially surrounded by insulation () disposed within a cylindrical shroud (). The electrode module () radiantly heats the steam module with resistive heating elements (). The thermocouple module () includes thermocouples monitoring first stage temperatures within and between pressure vessels (). PLC computer SCADA software () operates the generators. Thermocouple data is analyzed to control heater temperatures, the water feeding system (), and outputted steam temperature. PLC software () provides operating logic () establishing a start up subroutine (), a ramp up subroutine (), a steady state subroutine (), and a shut down subroutine ().

Methods for super heated steam generation

A water-soluble branched polyhydroxyetheramine, wherein the branched polyhydroxyetheramine is prepared by reacting an amine having two reactive hydrogen atoms with a diepoxide to form a polyhydroxyetheramine and then reacting the polyhydroxyetheramine with an N-alkylating agent, an aqueous composition comprising the branched polyhydroxyetheramine and use of the branched polyhydroxyetheramine to modify the permeability to water of a subterranean formation are disclosed.
