Abstract: Method and Apparatus for injection steam of know quality into a subterranean reservoir containing hydrocarbon fluids, to enhance or stimulate production of said fluids through a production well. Production stimulating steam from a pressurized source is injected into the reservoir by way of a critical flow venturi and an injection well, in a manner to maintain the steam at a desired pressure and flow rate. The venturi's constricted throat is formed as a function of the stimulating steam's original characteristics.

Abstract: A petroleum stream microwave watercut monitor of the present invention includes a test cell having a petroleum flowing through it. A source, connected to a first antenna located within the test cell, provides microwave energy to the first antenna so as to irradiate the petroleum stream in the test cell with microwave energy. A second antenna located in the test cell and connected to a detector outside of the test cell receives the microwave energy that has passed through the petroleum stream and provides it to the detector. The detector provides an intensity signal corresponding to the received microwave energy. An indicator provides an indication of the watercut of the petroleum stream in accordance with the intensity and the phases difference between the microwave energy provided by the source and the received microwave energy. The test cell means also includes means for reducing an amount of debris in a portion of the petroleum stream flowing between both antenna.

Abstract: The flow rate monitor includes a test line containing a chamber wherein the test line is declinated at a predetermined angle so stratification of liquid and gas will occur in the chamber. A sample stream is removed from the liquid in the chamber and provided to a separator which separates the gas from the sample stream to provide a gas output and a liquid output. The gas output and the liquid output is returned to the test line. The water cut of the liquid output is determined while the pressure of the composite petroleum stream is sensed along with the temperature. The volumetric flow rate of the composite petroleum stream is monitored and the flow rate signal is provided. The density of the composite petroleum stream is also monitored. The flow rate of all three coponents of the composite petroleum stream is determined in accordance with the temperature signal, the pressure signal, the water cut signal, the flow rate signal and the density signal.
