Abstract
The objective of the project is to reliably and economically identify and assess flow and well production, or well control events and conditions, for the purpose of preparing the appropriate response actions. The project builds on the work accomplished in RPSEA DW1301, concluding critical research needed to close key measurement gaps. The project puts emphasis on the development of techniques and methods that reduce the risk of uncontrolled fluid emissions from subsea equipment, such as blowout preventers, wellheads and Christmas trees, and risers and flowlines.

The key deliverables of the project include a technology workshop and a comprehensive final report summarizing the results of the five technical tasks outlined, which are:

• assess and refine state of the art subsea sampling practices
• develop sensor insertion mechanism to put flow sensors in contact with process fluid
• develop and test downhole HP/HT flow measurement
• evaluate flow modeling in multiphase transient conditions
• develop techniques for diagnosing fouling of measurement devices
