pdf  Fluid type determination for oil and gas fields in the southern Denisov Depression (Timan-Pechora Province)
A number of large-, medium- and small-sized oil and gas-condensate fields has been discovered in the Denisov Depression of the Timan-Pechora Basin. Moreover, there is a long list of drillable prospects in the area. Quite often, some wells in this area produce oil while other wells, nearby and with identical hypsometric conditions, produce gas. An integrated model explaining this phenomenon and allowing the prediction of fluid type for future fields has not been developed to date. To solve this specified problem, genetic prerequisites for oil and gas field formation in the area have been studied carefully. Well testing and fluid sampling conditions have been thoroughly examined. Data on the composition of liquid and gaseous components of reservoir hydrocarbon systems have been analyzed. Interpreted modeling of fluid type in discovered fields has been performed. As a result, for the first time in the Timan-Pechora Province volatile oils have been identified. They have been characterized in comparison with oils. An alternative model for fluid type in some previously discovered fields has been proposed. Optimum conditions for well testing and fluid sampling in the southern Denisov Depression have been suggested.

Keywords: deep buried deposits, volatile oil, gas condensate, gas-oil ratio, hydrocarbon composition, Denisov Depression, Timan-Pechora Province.

pdf Tectonical and geochemical preconditions for petroleum potential of Chernyshov ridge
The Novovorgamusyursky shaft was distinguished on the basis of the velocity model. New insights into the Chernyshev ridge as a part of Varandey-Chernyshev aulacogene are provided. The authors analyzed the probability of filling the identified traps by hydrocarbons from the major generation centers in Kosyu-Rogue depression, in Varandey-Chernyshev aulacogene with resource estimated at hundreds of millions of tons. There are preconditions for the preparation of the shaft traps for deep drilling.

Keywords: geological surveys, seismic surveys, hydrocarbon resources Varandey-Chernyshev aulacogene, Novovorgamusyursky shaft, Timan-Pechora province.
