Consequently a number of methods are available to measure molecular weight of crude oil and crude oil products. Molecular weight may be calculated from viscosity data (ASTM D2502). The test method requires viscosity data from different temperatures, typically at 37.8 °C and 98.9 °C (100 and ...
Reservoir fluid properties such as crude oil viscosity, oil formation volume factor, bubble point pressure, solution gas oil ratio, gas formation volume factor, isothermal compressibility and crude oil density are very important in reservoir engineering computations. An accurate description of reservoir fl...
