Achieving accurate measurement over a large flow range at high pressures in a corrosive offshore environment can be a major challenge to optimizing well production. This was the challenge for a major oil and gas producer in Thailand that planned to maximize the production from one of their mature fields using gas lift. The oil and gas producer began by using turbine flow meters. The turbine flow meter internal moving parts got affected due to long hours of continuous operation and corrosive offshore environment. The customer had to maintain spares of rotors & blades of turbine meters. The Rosemount 8800 Vortex Flow Meter turned out to be a maintenance-free solution with significant advantages. As a result, the oil and gas producer standardized the Rosemount 8800 Vortex Flow Meters across all their gas lift operations. Production increased 2 bpd in the first year resulting in significant cost savings.
