As more subsea projects mature and with increasing understanding of operations involving subsea wells, the industry is constantly faced with the constraints and challenge posed by the requirements for metering, sampling, well testing and allocation. These challenges are even more pronounced in cases where flow assurance issues play a role especially for long tie-back systems. Current regulation in the Nigerian sector has yet to catch up with these developments and as such operators struggle to meet the requirements.
A number of possible solution to the seeming problems or issues are under study, and with updated knowledge of the systems, it has become imperative to articulate and formulate strategies and philosophies for resolving or addressing the metering challenge for operations in Deepwater Nigeria.
This article analyzes one of such solution in the application of subsea multiphase flow meters
