In DNV's deep dive study for OG21 on “Low-emission technologies to decarbonise the Norwegian petroleum value chain”,  low shear chokes and pumps with variable speed driveare listed (p. 82) amongst successful and mature technologies to achieve energy efficiency.

The report is available at OG21's web page (og21.no)
 

• "Variable speed drive (VDS) is standard and mature technology applied for most new projects and reduced energy consumption significantly due to no need for choking and recirculation for flow control."
• "Low turbulent chokes are common technology applied with success, primary for oil fields to enhance separation efficiency and reduce energy consumption."
