.... This brine was also used as dispersed fluid for nanoparticles. The synthetic paraffinic oil was used in for IFT measurement and coreflood experiment. It has density and viscosity about 0.803 g/cm 3 and 1.96 cP respectively. Nanofluids with weight concentration 0.01 and 0.05 wt.% were made from brine...

In these experiments, water based drilling fluids containing different types of salt (NaCl and KCl) and at different concentrations were tested by a state-of-the-art high pressure high temperature viscometer. In this paper, the effect of different electrolysis (NaCl and KCl) at elevated...

.... Also, it is necessary to examine the behavior in core samples. One of the main parameters determines the success of foam flooding is the selection and concentration of proper foaming agents (surfactants). In two-phase colloidal systems such as bulk foam, a thin, intermediate region or boundary...

... runs for around 48–72 hours and many tests may be needed to optimize fluid composition. In this work, a method/model is developed to predict final swelling volume ( A ) as a function of the Cation exchange capacity (CEC) of the shale and salt concentration in the fluid (prominent factors affecting...
