- Abstract:
- Monitoring of the multiphase flow at the wellhead eliminates the need for dedicated testlines from remote wellhead completions, and the need for a dedicated test separator at the processing facility. A multiphase flowmeter at the wellhead will also allow improved well control, and hence better reservoir control. For remote or deep subsea wellhead completions the savings and operational benefits offered by this new technology are quite extensive.
In summer of 1997, Petrobras installed a Fluenta multiphase meter in a subsea production manifold, at 450 meter water depth at the Albacora field offshore Brazil. 20 months later, at the end of January 1999, the meter was powered up, signal communication was established, and calibrations were checked and verified. First oil through the meter was in early May 1999. The paper reports the operational experiences from first year of operation, and providse evaulation of measurement performance, compared to the conventional test separator.
Since the development of the subsea multiphase meter for Petrobras, the technology has been further developed to a new, compact design for ROV installation at water depth down to 2500 meters. Design and intervention concept for this new version is presented. - Download:
