Paper Number: SPE-201223-PA
Published: 15 October 2020
... . In 2012, a project started with the objective of developing a low-degrading valve for polymer-flow applications related to enhanced-oil-recovery operations (Stokka 2013 ). The development work includes testing at small- and large-scale facilities, and with various polymer types, polymer concentrations...

...Abstract Abstract During the last years, a lot of work have been done focusing on development of low shear valves solutions to be applied on petroleum primary process plants. The main goal of the low shear valve is to generate water-in-oil (WiO) and oil-in-water (OiW) emulsions that can...

... Abstract Turbulence and shear in conventional choke and control valves do mix and emulsify petroleum fluids. A typical consequence is reduced separation efficiency of downstream gravity separators, resulting in retarded oil-water separation. A new cyclone-based low shear valve is developed...

... phases is degraded. Over the last few years, low-shear valves targeting petroleum processes have emerged on the market. This paper presents four separate live-fluid experiences from low-shear valve installations, each surveyed and documented by an independent third party. Three of the installations refer...

... in the test packer. The sealed oil chamber valve design in the test packer is similar to the bypass tool, but with one notable exception. The pressure from the high-pressure chamber had to be vented to the low-pressure chamber after a certain travel distance as to mimic a shear device. This is important...
