Belfroid, S.P.C. (author), Schiferli, W. (author), Veltin, J. (author), Veeken, K. (author)This paper discusses the multiphase flow mechanism responsible for gas-well liquid loading. It demonstrates that the conventional idea of droplet flow reversal (Turner et al. (1)) does not capture reality and that actual observations are better described by film flow reversal phenomenon. The benefits of different types of tubing wall...conference paper 2011

(author)A distributed chemical sensor is developed by coating multiple Bragg gratings in a single glass fiber with chemical responsive coatings. The composition of the coating is tuned to the target chemicals to be measured and the optical response of the coated grating is optimized by changing the coating thickness. Specific recoaters were used to...conference paper 2011
