Comparative Characteristics of the Properties of Oil of the Orenburg Region Fields

N G Myazina, V V Kuzminа

Abstract


Physico-chemical properties of oil are important for making design and technology decisions in the process of production and transportation of hydrocarbons and derived products. A number of oil fields related to the different geological setting of the Orenburg oil and gas province were chosen for comparative analysis of oil physico-chemical properties. Geochemical processes of transformation of organic matter govern a regularity of occurrences distribution of crude oil of different composition during sedimentation before the formation of deposit, and hydrocarbons in the deposits after accumulation as well. General characteristic of selected oil fields is presented. It was found that there is no significant difference in the oil properties throughout the area of the Orenburg sub-salt fields; light or medium density oil predominates; Tarashchanskoye, Garshinskoye, and Morgunovskoye oil has a high freezing point; and oil ranges from low-sulfur to high-sulfur.
