“…One of the features claimed for of multiphase metering technology is that the measurements performed by these meters are more consistent than measurements made by the conventional test separators (9). Table 4 shows the results from a recent 24 hour test for a number of wells compared with historical data for the same wells.…”

In many mature fields production well testing is limited by the availability of test separator. Prior industry attempts to utilize the new technology of multiphase metering to fill this gap has been hampered by the cost of multiphase meters. This paper describes the development and field tests of a low cost portable multiphase meter. The meter utilizes the Coriolis flow meter technology combined with a microwave based water cut meter that can measure WC in the 0-100% range. The combination of these techniques provides a light weight metering package that can be mounted on trailer for portable well testing. This multiphase meter can measure oil, water and gas without separation of the production stream at low GOR. These applications can be found in mature fields with low GOR and in heavy oil fields.The multiphase meter was subjected to field qualification tests prior to deployment in a West Texas field. The paper describes the results from the qualification tests and the performance history during the 18 months of deployment in the field. Well test data from the multiphase meter is compared to conventional test separator and grab samples. Comparison between the test separator and the multiphase meter shows average liquid flow deviation of about ±7%. The water cut was measured within 1-2 points of the water cut from the test separator.

“…Production allocation based on periodic well tests has long been accepted practise in the industry for this application, although the preferred method is to keep production from separate pools separated until measured downstream of group three phase separators. The introduction of wellhead multi-phase flow meters has greatly improved the quality of well-level flow allocation, though it is still limited in its application 14 .…”

fax 01-972-952-9435. Abstract Marginal reserves are hydrocarbon accumulations too small or too difficult to recover economically by themselves under prevailing fiscal terms. Stacked reservoirs containing marginal reserves are often passed over in favour of more prolific zones containing economic volumes. The opportunity to develop the marginal reserves in conjunction with other marginal reserves, or with larger reserves by commingling (and by doing so make them economic) is sometimes overlooked by operators due to government regulations prohibiting commingling. This paper explores the concept of developing marginal and/or other reserves by commingling using intelligent well technology. It reviews the current status of intelligent well technology and government regulations on commingling in a number of regions. The potential for exploiting marginal reserves in the North Sea, Nigeria and the Gulf of Mexico is also considered.

“…Information on the flow rates is available to the operator immediately after starting the production. Although the traditional method of separating the phases before measuring is still used for fiscal metering [3], MPFM systems are now increasingly employed in various hydrocarbon production systems, where the accuracy requirements are less stringent.…”
