Exact and reliable production well testing allows to quantify the volumes of fluids produced and additionally to diagnose the anomalies on time to carry out early adjustments in the wells, in order to have a production with the highest efficiency. The Portable Test Separator SEPARATRUCK appears like an economic alternative of measurement in wells production in the Venezuela's Orinoco Heavy Oil Belt. The project consisted on the elaboration of a design methodology, based on studies made in the field that allowed determination of the main faults in the measurement of the production with the traditional test equipments, establishing specific considerations for the design of a new, portable and automated in all its functions measurement equipment. The mass, is the primary unit of measurement and because it is not affected by the changes of viscosity, density, electrical conductivity, pressure and temperature; this parameter turns out to be simplest and at the moment most reliable to measure. For that reason, the prototype will be equipped with two mass flow and density meters, in addition to a radar device able to control different fluid levels configurations; this, in combination with technological improvements of the Coriolis measurers, will provide a wide rank of ability allowing to adapt the configuration of the system, resulting in an equipment able to test wells that produce from different reservoirs (different API gravities) and at variable production rates (different GOR), diversifying the measurement, making flexible and popularizing the equipment. The design calculations were validated by means of numerical simulation, obtaining a portable test separator able to handle upto 2,500 bbl diluted heavy petroleum, with water cuts between 0 and 100%, and a maximum gas rate of approximately 5 MMscfd.
