Title: Exploratory Characterization of a Perfluoropolyether Oil as a Possible Viscosity Standard at Deepwater Production Conditions of 533 K and 241 MPa

Abstract

DuPont’s perfluoropolyether oil Krytox® GPL 102 is a promising candidate for the high-temperature, high-pressure Deepwater viscosity standard (DVS). The preferred DVS is a thermally stable liquid that exhibits a viscosity of roughly 20 mPa∙s at 533 K and 241 MPa; a viscosity value representative of light oils found in ultra-deep formations beneath the deep waters of the Gulf of Mexico. A windowed rolling-ball viscometer designed by our team is used to determine the Krytox® GPL 102 viscosity at pressures to 245 MPa and temperatures of 311 K, 372 K, and 533 K. At 533 K and 243 MPa, the Krytox® GPL 102 viscosity is (27.2±1.3)mPa∙s. The rolling-ball viscometer viscosity results for Krytox® GPL 102 are correlated with an empirical 10-parameter surface fitting function that yields an MAPD of 3.9 %. A Couette rheometer is also used to measure the Krytox® GPL 102 viscosity, yielding a value of (26.2±1)mPa∙s at 533 K and 241 MPa. The results of this exploratory study suggest that Krytox®GPL 102 is a promising candidate for the DVS, primarily because this fluoroether oil is thermally stable and exhibits a viscosity closer to the targeted value of 20 mPa ∙ s at 533 K and 241 MPa thanmore » any other fluid reported to date. Finally and nonetheless, further studies must be conducted by other researcher groups using various types of viscometers and rheometers on samples of Krytox GPL® 102 from the same lot to further establish the properties of Krytox GPL® 102.« less
