ABSTRACT:
In a broad aspect, the invention is a method and apparatus for the downhole metering and control of fluids injected into a subterranean formation, and includes: a housing sealably connectable to a well tubing; a turbine meter disposed in the housing which provides an indication of flow rate therethrough to a control panel at the surface; and a variable orifice valve means in the housing which alternately permits, prohibits, or throttles fluid flow therethrough. The system has a communication link to the surface, an onboard motor which powers a hydraulic system in the housing that controls the throttling action of the variable orifice valve means, and a system to monitor and report downhole pressure and temperature. The system has the option of reversing the action of the turbine to monitor production from the subterranean formation.
