Abstract: This invention is comprised of a method and apparatus for increasing fluid flow from weak geothermal wells that marginally or cannot, on its own, flow into a production gathering system by passive use of squandered energy inherent in a strong well geothermal well. The apparatus is comprised of a venturi-like nozzle called an eductor and associated piping connected to both the weak and the strong wells and the production gathering system. The method utilizes the eductor apparatus to harness some of the energy from strong well to induce fluid flow from the weak well by reducing the flowing back-pressure for the weaker well.

Abstract: The present invention entails a device for separating liquid and entrained solids from a vapor stream traveling under pressure within a conduit by inducement of the annular boundary layer within the pipe wall, to a stratified region flowing along the bottom of the pipe, for removal by way of a condensate drain pot.

Abstract: Multi-phase flow measurement in a conduit is accomplished by generating a spin in the flowing fluids and/or entrained solids, by which the centrifugal force separates the flowing components by density. The isolated flow in the central part of the conduit is measured. The denser isolated fractions flowing against the conduit wall can be measured. An overall composite parameter can be measured. These measurements can then be mathematically solved for their individual flowing components. The flowing components re-mix downstream of the apparatus.

Abstract: A device for metering a liquid and a vapor flowing through a conduit generates a spin to the two-phase flow, by which the centrifugal force separates the liquid phase from the vapor phase. Next, the liquid-vapor rate and the isolated annular vapor rate are measured. These measurements can then be mathematically solved for the individual flowing components. The vapor and liquid re-mix downstream of the apparatus.

Abstract: A device for separating liquid droplets and solids out of a geothermally produced vapor stream traveling under pressure through a pipeline comprising a first means for inducing a force in the vapor stream to induce the droplets and solids to migrate to the pipelines inner wall and a second downstream means for collecting those droplets and solids.
