Coriolis-based net oil computers gain acceptance at the wellhead

Full-range, water-cut capability and a nonintrusive nature enable the Coriolis-based net oil computer (NOC) to meter produced fluids directly from the wellhead. The Coriolis-based NOCs are cost effective, especially in high water-cut applications. Field experience shows the units are rugged, reliabl...

Description
Summary:Full-range, water-cut capability and a nonintrusive nature enable the Coriolis-based net oil computer (NOC) to meter produced fluids directly from the wellhead. The Coriolis-based NOCs are cost effective, especially in high water-cut applications. Field experience shows the units are rugged, reliable, and accurate when properly installed and operated. The NOC system continues to evolve with improvements in implementation procedures and techniques to enhance operation and expand application opportunities. Increasing numbers of Coriolis-based NOCs are used simultaneously to measure crude and water production from individual wells or leases. In this NOC system, the Coriolis force flowmeter serves as both water-cut analyzer and flowmeter. Compared to other conventional measurement systems, this technology offers 3 advantages: 1. measures full-range water cut, 2. reduces repair frequency and test cycle time, and 3. lowers overall capital costs.
