... 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...

... viscosity up to 300F. The new surfactant system is completely compatible with HCl, brine, and even high iron contamination. Rheological studies defined the operational temperature limit where viscosity was sufficient for the new VES system to be used successfully as diversion agent. It was found...

... failures. Under two-phase flow conditions, loss of pump performance or gas lock condition can be observed. Under viscous fluids, the pump performance degrades as well. This paper provides a model on the effects of viscosity and two phase (liquid & gas) fluids on electric submersible pumps (ESPs), which...

... 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...

... 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...

... concentration viscosity Introduction The combination involving alkali-surfactant-polymer (ASP) has been recognized as a cost-effective chemical flooding process for light and medium oils. The success of this process depends on the identification of a proper alkali, surfactant, and polymer and the way...

... constant shear rate while apparent viscosity had been recording. Apparent viscosity is almost constant up to initial gelation time in which viscosity starts growing up. Initial and final gelation times, initial and final viscosities are parameters that can describe the behavior of a gel system...

... Abstract Several polymer formulations were prepared and they have been characterized for their physical and chemical properties with viscosities ranging from 14 cP to 418 cP for concentrated solutions and from 3.5 cP to 15.8 cP for diluted solutions when measured at 80°C. Several polymer...

Such errors can lead to the conclusion that low-quality ("quality" defined as the percent of foam in the slurry) cement foams have lower viscosities than their base fluids; such conclusions have been reported by other research organizations. The following attributes of the "bob and sleeve" conventional...
