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.

Abstract: Where a subsea well is completed for production or water injection service, a subsea christmas tree must sealably connect with both the wellhead and the pipeline(s) or subsea manifold template pipework in order that fluids may flow out of (or into) the well. An intermediate series of pipework loops mounted within a space frame, herein referred to as a Flowline Connection Module (FCM) is removably interposed between the subsea wellhead and the subsea christmas tree to facilitate the piping connections. Each of the modules is further provided with removable U-looped pipework spools at its extremities and said spools may contain adjustable chokes to control the flow of fluids into or out of the wells. The replacement of one choke spool with another may adapt the service function of the well from, for example, production to water injection.
