Well testing is a complex phenomenon and can be performed on onshore as well as offshore wells. In an offshore platform, each well or group of wells can behave independently, the reservoir characteristics in the form of production/pressure profile being different. Sometimes, the well testing becomes significant due to contractual obligations between partners who share the same reservoir. The well-bore assessment in combination with shut-in data and test results data can be used to prevent damage to the well bore activity [1]. The purpose of Multiphase Flow Meter (MPFM) is to determine the oil, water and gas volumes and mass flow rates from the multiphase stream produced by the wells in a typical offshore platform. A conventional method would be to use a test separator vessel, which by virtue of its design, separates the three phases each of which is individually metered at the outlets.
