    Abstract: A pneumatic timing valve includes a spool and seal system having a first seal cartridge and a spool. The first seal cartridge has an annular body with radial ports. The spool is positioned within the first seal cartridge and movable between a first and second position. The spool has a central bore and radial ports that intersect the central bore. The radial ports of the spool complement the radial ports of the seal cartridge. The seal cartridge radial ports, the spool radial ports, and the central bore of the spool define fluid flow passages.

    Abstract: A process for recovering hydrocarbons from an in situ formation. The process includes the steps of injecting solvent though an injection well into an underground extraction chamber having a hydrocarbon extraction interface, warming the hydrocarbons at the extraction interface to cause the hydrocarbons to flow downwardly by gravity drainage. Barrier gases naturally emerge in the chamber as a result of the extraction process and are removed from the extraction interface to improve heat transfer from said solvent to said interface. The last step is to recover liquids such as hydrocarbons and water through a production well. The invention provides a separate flow path to remove hydrocarbon gases from the chamber at a preferred location. The preferred location is near the top of the chamber where the accumulated barrier gases help to limit the heat loss and can also provide a barrier to help maintain chamber integrity and confinement.

    Abstract: The invention relates to a method for improving the supply of water from a layer in the earth to a source which is located in the ground or a well, especially a water procurement well, said source or well consisting of a drill hole extending as far as the above-mentioned earth layer or groundwater. The well or part of the well is initially sealed by cutting off means which include an inflow pipe, whereby the lower part of the well is sealed in an airtight manner in an upward direction and can be pressurized by supplying a gas, liquid or a solid. According to the invention, the well is initially filled with gaseous carbon dioxide below the outflow opening of the inflow pipe. The carbon dioxide is subsequently guided through the inflow pipe, whereby the water located close to the end of the pipe and the earth layer is frozen at a specific distance from the outflow opening of the pipe. After a specific time period during which the well re-thaws, the fine particles of the deposits which are dissolved as a result of the inventive method are removed from the well, along with the pump water, with the aid of the pumping out means.
