The invention relates to the use of a compound of Formula 1: R1-Sx(0)y-R2 to decrease the viscosity of an heavy oil, wherein R1 is a C1-C4 alkyl, R2 is C1-C4 alkyl or H, x is 1 or 2, and y is 0, 1 or 2, as well as a method for producing oil and/or gas from a ...
Viscous liquids like honey, syrup, and oil flow slowly, and less viscous liquids like water and gasoline flow quickly. The Navier–Stokes (NS) equation can be used to describe the motion of non-perfect fluid in fluid mechanics, where the shear viscosity coefficient and the bulk viscosity coeff...
In the formula, [[eta].sub.1] is viscosity coefficient of Kelvin bulk, GPa. CREEP BEHAVIOR AND ACOUSTIC EMISSION CHARACTERISTICS OF COAL SAMPLES WITH DIFFERENT MOISTURE CONTENT There are no simple relations by using which the viscosity coefficient could be reconstructed from the measured attenuation...
