Electric roller screw-activated choke delivers quick, accurate response when installed in manifold

Many existing hydraulic and electric chokes used to control surface backpressure during managed pressure drilling (MPD) weren’t specifically designed for use in MPD operations. Tolomatic set out to design a choke that would deliver a quick and accurate response in the face of changing pressure demands encountered during MPD operations. In this video from the 2018 SPE/IADC Managed Pressure Drilling and Underbalanced Operations Conference on 18 April in New Orleans, La., Ryan Klemetson, Business Development Manager for Tolomatic, explains the drivers for developing ServoChoke, an electric roller screw-activated choke, and how it works. He also discusses the company’s collaboration with Pruitt Optimal to build the choke into Pruitt’s manifold, as well as the results observed when the manifold was deployed.
