in this paper, a very efficient method, called single matrix block analyzer (smba), has been developed to determine relative permeability and capillary pressure curves from spontaneous imbibition (si) data. smba mimics realistically the si tests by appropriate boundary conditions modeling. in the proposed method, a cuboid with an identical core plug height is considered. the equal dimensions of...

backgrounds and aims: methylglyoxal (mgo) is an –α, β dicarbonyl aldehyde inevitably produced from triose-phosphate intermediates of glycolysis, and amino acid. increased mgo in blood leads to alterations in coagulation, clot permeability and thus, atherosclerosis in children with diabetes; however, the precise mechanism is not clear. the present study aimed to compare different concentrations ...

The effect of dry material, glycerol and ratio of water to seed in alyssum homalocarpum films on their thickness, transparency, moisture content, tensile strength, elongation and water vapor permeability was investigated using mixture response surface methods. Dry material and glycerol were important factors influencing tensile strength, elongation and water vapor permeability. Ratio of water t...

the simultaneous flow of oil and water in porous media is described by relative permeability curves, mainly derived from laboratory experiments. relative permeability is of paramount importance in predicting reservoir production performance and drive mechanisms and its value depends largely on the volume fraction of fluids present in the test samples. nowadays x-ray scanners are one of the most...

Objective(s): Since microbial contamination can reduce the shelf life of the foodstuff and there is a potential for the growth of some pathogen microorganisms, films containing antimicrobial agents were produced, which are also biodegradable. In this study, the effect of 1, 3 and 5% nano-zinc oxide on antimicrobial properties and permeability of poly lactic acid film was invest...

Water injection is used as a widespread IOR/EOR method and promising formation damages (especially mechanical ones) is a crucial challenge in the near-wellbore of injection wells. The magnesium oxide (MgO) NanoParticles (NPs) considered in the article underwater flooding experiment tests to monitor the promising mechanical formation damage (size exclusion) in lab mechanistic scale include m...
