This has generated tremendous interest for researchers and end users. It is now considered as a special discipline with millions of dollars invested in R&D to fine tune the technology and increase benefits to the customers. Typical applications of Multiphase meters that assist the Oil and gas producers include:
|
|
 |
Reservoir Management |
|
|
Appraisal well testing |
|
|
Production monitoring |
|
|
Allocation metering |
|
|
Turnkey well testing service |

Multiphase Meters: The Haimo Multiphase Flow Meters adopted by Bell Oil & Gas is a combination of a gas/liquid two-phase (in-line) flow meter and a full-range three-phase water cut meter. The gas/liquid flow rate measurement and water cut determination are carried out independent of each other. The gas/liquid two phase flow meter consists of a Venturi and two identical single (59.5 KeV) gamma sensors. The full range three-phase water cut meter comprises a dual energy (22 and 59.5 KeV) gamma sensor and a flow conditioner located upstream. Both the gas and liquid flow rates are measured upstream of the flow conditioner in the two-phase flow meter, which is in-line without needs of any flow conditioning or separation. The Dual gamma meter measures the water cut. Net oil flow rate is finally calculated based on the gross liquid and watercut.

Watercut Meters: Watercut meter is an integral component of the the Haimo multiphase meter utilized by Bell Oil & Gas. The meters works on low energy gamma photo absorption principle. Based on measurement requirements and the presence of various phases, the customer has a choice of Single gamma meters or Dual gamma meters. Single gamma meters measure two phases, for ex. Oil and water in the absence of gas OR liquid and Gas. Dual gamma meters measure the watercut in the presence of gas OR can be used to compensate for salinity in produced water in the absence of gas. Typical accuracy of measurement of water cut is +/- 1% abs. for the full range of watercut in the absence of gas.
