4 1. Introduction

Construction initiative of the multiphase flow loop at Tiller near Trondheim, Norway was
pioneered by Esso Norge looking to evaluate the stability of multiphase oil and gas production
from offshore reservoirs, and supported by this and other companies. The cost to construct this
flow loop was over 26 million in 1980 US dollars. The choice of location was economically justi-
fied because the Norwegian sector of the North Sea showed promising acreage and because the
Norwegian law allowed some research cost to be deducted from taxable revenue. Numerous sets
of data were collected from this test facility which, to this day, are used to validate multiphase
software (Caspersen et al., 2011).
The Tiller multiphase flow loop shown in Fig. 1.1 is perhaps the one most important facil-
ity used for development of data sets for validation of several multiphase flow models.
