Аннотация

Bazhenov Formation is a well known unconventional reservoir within the West Siberian Petroleum Basin. This deposits contain a huge amount of kerogen - up to 30 wt. %. One of the main characteristics of source rocks for oil generation is kerogen thermal maturity. Maturity level shows the residual generation potential and the possible amount of hydrocarbons in natural reservoirs and amount of hydrocarbons that can be generated by source rock using thermal enhanced oil recovery methods. This work proposed complex investigations including pyrolysis for core samples before and after bitumen extraction. According to the scheme of maturation and distribution of pyrolysable hydrocarbon groups in the unconventional source rocks we can use complex of Rock-Eval parameters such as generative organic carbon (GOC) to remaining organic carbon ratio (GOC/TOC*100%), hydrogen index in samples after extraction (HIex= S2ex/TOC*100%), productivity index (PI=S1/(S1+S2) and Tmax to estimate maturity level of organic matter. Using geochemical and pyrolysis parameters we can evaluate maturity of the Bazhenov Formation organic matter which is important for reserves estimation and distinguishing areas of natural and technically stimulated reservoirs.
