Characteristics of the composition of crude oils of terrigeneous deposits of the Volgograd region alongthe Volga are examined. It is demonstrated that crude oils of these deposits are light, paraffinic, low-sulfur, and low-resin. Their original parent matter is represented by the specific organic matter of terrigeneous deposits, which accumulated and metamorphosed under reducing conditions.The composition of crude from the Volgograd region is distinguished by broad diversity, resulting from complex multistage formation, reformation, and breakdown of deposits within a broad generational-accumulation system of the subsalt Paleozoic on the western border of the near-Caspian depression and its platform-like continuation. In this system, the crudes, which are confined to deposits of the terrigneous Devonian in the extreme northwestern section (right-bank) of the Volgograd region along the Volga, are particularly isolated. This is the western boundary of the commercial petroleum content of the border section in the near-Caspian depression, which is attracting the attention of researchers for various reasons. The Tersa field falls within the region in question. Characteristics of the crude from these deposits, which are also characteristic of other crudes from the Volgograd region along the Volga, are examined in this study based on crude extracted from well No. 76 in the Tersa field.A basic characteristic of the Tersa field is its finely-divided block structure, and complicated disjunctive tectonic and lithologic nonuniformity of the seams with respect to area and section, which have affected the properties of the crudes. The western boundary of the Tersa structure is a regional longitudinal fault. Two seams of the Ardatovsk horizon, which are represented by a terrigneous complex of rocks, are oil-bearing in the field.The crudes of this region have a density ranging from 800 to 810 kg/m 3 , and a gas contant of from 70 to100 m 3 /ton, and contain 8-15% of solid paraffins. The crudes are low-sulfur and low-resin. These crudes are a valuable feedstock for the production of high-index oils, waxes, etc. Based on physico-chemical properties
