Ff. Hamidullin et al., Studies on the changes of produced oils physical-chemical properties during development of Romashkinskoye field, NEFTY KHOZY, (7), 2000, pp. 31-33
Analyzed are physical-chemical properties of ails at Yujno-Romashkinskay, A
lmetievskaya, Minibayevskaya, Abdrahmanovskaya, Zai-Karataiskaya and Alkeev
skaya areas of Romashkinskoye field. Stated is similar for all areas consta
nt reduction during development process of saturation pressure, gas-oil rat
io, oil formation volume factor, compressibility factor, increase of sulfur
, wax, resins and asphaltens content in oils.
