The article discusses the controversial issues of well log correlation of the Riphean, Vendian, Cambrian and Mesozoic sequences, which is prospects for oil and gas within the Aldan-Maya petroleum region. The author's version of the stratigraphic correlation is based on the interpretation of logging data, seismic surveys, core description, archival and published materials. The results obtained can be used for stratigraphic picks correction and structural maps plotting.

Complex interpretation of seismic and parametric drilling data is performed. The data for interpretation are obtained within the conjunction zone of the Kureyka syncline and the Anabar anteclise. As a result of complex interpretation the structural maps on the bottom of Vendian and the top of the Kuonamka formation are constructed. Map of the Vendian terrigenous complex was constructed. High prospects of oil and gas potential of the lower-middle Cambrian sediments are shown. Based on the analysis of logging data, core description and detailed correlation of time sections, the litho-acoustic models were compiled for two profiles crossing the barrier-reef system, and two-dimensional synthetic time sections were calculated. Obtained results confirm the correctness of the ideas about the internal structure of the Vendian-Cambrian complexes.

Based on geological and geophysical data, such as deep drilling, well logging, seismic surveys CDP-2D, DSS, SK-VSP a sedimentary cover structural model of the Vilyui hemisineclise to the lower Cambrian roof is constructed. According to seismic data interpretation, the ubiquitous development of the oil and gas source Kuonamka formation is predicted within the internal boundaries of the Vilyui hemisyneclise, where it formed an extensive center of hydrocarbon generation. Clinoform-built Middle Cambrian rocks (Maysky stage) overlie Kuonamka formation. The reservoirs development in the Maysky stage rocks is substantiated, a forecast map of porosity coefficients is generated.

We present how to detect reservoirs by the 3‐D normalized full gradient (NFG) of gravity anomalies constrained by seismic and drilling data. The normalized full gradient represents the full gradient of the gravity anomaly at a point divided by the average of the full gradient at the datum. The closed minima on an NFG map indicate the occurrence and horizontal locations of the centers of mass of density anomalies related to oil reservoirs. This information can be used to select well locations in an oil field. On a cross‐section, the closed minima can be used to estimate the depth to centers of mass of possible hydrocarbon reservoirs. Some characteristics of the NFG are calculated for a hypothetical case of an anticline saturated with oil and gas. The relationship of these characteristics to the geometry and physical parameters of the anticline is studied. Modeling studies show that the NFG largely depends on the number of terms in the Fourier series used to calculate it, and it closely related to the length of the gravity profile or the size of the study area. Applying the NFG method to the Shengli oil field, i.e., using closed minima of NFG alongside drilling data, showed an effectiveness of up to 70%. These results were used to select well locations with the result that some high‐production gas‐bearing strata were discovered by drilling.

The article describes the recent distribution of temperatures of rocks in the roof of Tyumen and Malyshev suites for the whole territory of the West Siberian sedimentary basin. A map of temperature changes in the regional oil and gas bearing horizon U2 was built. The prognosis of the temperatures distribution in the roof of Malyshev suite on the understudied by deep drilling in Arctic areas is made. The analysis of placement of the deposits in the Bath with different phase state of the hydrocarbons is presented.
