... Abstract Most of the existing correlations for estimating gas viscosity were developed in mid 60's and 70's of the last century. Limited number of data was used to develop them and their accuracies are questionable. Predicting accurate gas viscosity is extremely important in the oil and gas...

... also present the effect of temperature and shear rates on viscosity of gelling acids. However, there are no theoretical studies presented in the literature that describe the transport and reaction of gelling acids or their pH-dependent viscosity. Because gelling phenomena is the key for flow diversion...

... rate. Two-phase flow was used in pipe flow to investigate the possibility of drilling more than 10 laterals. The study shows how pressure at the junction can be used to determine the optimum lateral length as a starting point when designing multilateral wells. The parameters analyzed include viscosity...
