pdf The role of seismogeological analysis in the evaluation of the oil and gas potentiality of the Callovian-Oxfordian sequences of the southeastern part of the Kaimys Arch
This research has a great importance as it provides an new model for the distribution of oil-bearing Upper Jurassic reservoirs of the Yu1 level in the southeastern part of the Kaimys Arch. The data obtained as a result of drilling prospecting and exploratory wells within the Moiseev field and adjacent territories indicate a complex spatial distribution of the main productive unit Yu13. In many drilled wells, commercial oil inflows have not been received or oil and water inflows are characterized by low flow rates. The presence of hydrocarbons in the wells of the study area is not always controlled by the structural factor. This suggests the presence of oil deposits in traps of a “non-structural” type, the prediction of which is possible with a targeted choice of seismic attributes in the process of joint interpretation of seismic and deep drilling data. To implement this task, a 2D seismogeological modeling of the productive part of the studied section was performed in order to estimate the time interval and criteria for the manifestation of information of the considered target object (reservoir unit Yu13) in the seismic record. The implemented sequence of analysis of seismogeological information in the territory under consideration, including 2D seismogeological modeling, seismic facies and object-oriented attributive analyzes, made it possible to identify the areas of development of facies environments of the terrestrial part of the delta and foredelta. Within the zones under consideration, a forecast was made for the localization of reservoirs associated with the presence of deltaic channels and alluvial fans. In accordance with the structural features of the reservoir structure and the predicted zones of improved reservoir quality, oil-promising areas have been identified for setting up oil exploration and optimization of production drilling at already discovered accumulations.

Keywords: oil-bearing Upper Jurassic reservoirs, reservoir unit Yu13, seismogeological analysis, forecast of reservoir localization, southeastern part of the Kaimys Arch.
